NEWS Bombardier’s automated rail control starts operation on Delhi Metro Line 7 Bombardier Transportation, along with Delhi Metro Rail Corporation Ltd (DMRC), celebrated the end of 2018 with the opening of the final major section of the new, automated Delhi Metro Line 7. Equipped with Bombardier’s advanced rail control, the latest 9.8-km stretch of line to open runs from Lajpat Nagar to Mayur Vihar and is providing new rail links between the south and east of the city. S.S Joshi, Director Rolling Stock and Signalling, Delhi Metro commented, “The opening of this last section of our new, fully-automated Line 7 is a major milestone in the expansion of integrated public transportation in Delhi. The line is already easing pressure on the existing network and is improving travel for millions of commuters.” Rasmi Ranjan Ray, Head of Rail Control Solutions India, Bombardier Transportation added, “It has been a momentous experience to see the start of services on Delhi’s first fully-automated metro line. This latest section to open marks a major milestone for DMRC in its introduction of driverless, high-capacity services”. All four phases of Line 7, or the Pink Line, which have opened since March this year, are equipped with the BOMBARDIER CITYFLO 650 communications-based train control solution to support safe and reliable automatic train operations. CITYFLO 650 uses modern radio networks and moving block operation to provide centralised train supervision. The complete 58.5-km circular route from Majlis Park to Shiv Vihar Station will run alongside the city’s Ring Road and is the only line to intersect with all of the other six lines in the Delhi Metro system. A final 600-metre section will connect the two sections in service. The line is can support train speeds of up 85 km/hr, with a frequency as low as just over one and half minutes and its line opening will further support Delhi Metro’s vision to move four million passengers daily on the network.
SMA wins order for Indonesia CAF Power & Automation, a subsidiary of the Spanish CAF Group, has ordered 62 SMARTconverter 3 static inverters from German manufacturer SMA Railway Technology GmbH. The SMARTconverter 3, which is a static inverter of performance class 140 kVA + 20 kW, will be used in the Jabodebek project in Indonesia. These reliable static inverters are based on medium-frequency, potential separation technology, which gives them the specific advantages of being both lightweight and small in size. CAF Power & Automation has repeatedly chosen the SMARTconverter 3 for these reasons. The supplied static inverters will be fitted on the 31 Light Rail Vehicles that rolling stock manufacturer PT INKA will commission for revenue service on the Jabodebek - Jakarta, Bogor, Depok, Bekasi line. PT Industri Kereta Api – INKA, is one of the leading railway companies in Southeastern Asia and this project is one of the strategic moves by the Indonesian Government towards the improvement and modernization of passenger transit in the country.
Siemens to electrify Singapore extensions Siemens Mobility has been awarded its 3rd contract in Singapore in less than a year. The latest contract is for the electrification of the extensions to the Circle Line Stage 6 and the North East Line. The order is worth €70 million and will include the supply of the rail electrification system, for both DC and AC current, along with the overhead power lines on the North East Line. The overhead lines to be supplied will be the Sicat SR aluminum overhead busbar system (Siemens Catenary System Standard Rigid). Sicat SR differs to conventional overhead line systems, in that it requires a lower installation height and has a low voltage drop. In addition, it has a high current carrying capacity, shortcircuit resistance and reduced contact wire wear.

Commenting on this contract Michael Peter, CEO of Siemens Mobility said, "The extension of the Circle Line and the North East Line extends the mobility offer for millions of commuters in Singapore. With the electrification of the two lines, we are making an important contribution to decisively improving the availability of public transport in Singapore”. This latest contract follows 2 awarded to Siemens Mobility in 2018. In March, they were commissioned to supply the signalling equipment for the extension of the Downtown Line 3 and in September they received an order for the delivery of a Rail Enterprise Asset Management System.

NEWS CRRC & Downer win double-decker train order in Australia CRRC Changchun recently received a second order from Sydney for its double-decker trains. The order includes a total of 17 double-decker trains and post-delivery maintenance in Sydney. CRRC Changchun will design and manufacture the trains and its Australian partner, Downer, will provide maintenance support. The new trains will be designed to incorporate automatic temperature control systems and monitoring systems, as well as facilities for those with disabilities. The partnership between CRRC and Downer was established via the Waratah Train Project. The NSW Government ordered a total of 626 carriages in December 2006, which at the time made it the largest single rolling stock order in Australia. Working as a sub-contractor on the project, this was the first time that CRRC had been involved in the rolling stock industry in Australia. In 2015 CRRC and Downer decided to set up a closer cooperation and started a strategic partnership within Australia and New Zealand. This lead to two successes for the companies at the end of 2016, with orders won on the Sydney Growth Train and High Capacity Metro Train projects.
Alstom electrification for Bangalore Metro
Alstom has been awarded a contract by BMRCL to provide power supply and traction electrification for the 33-kilometre extension to Bangalore Metro under Phase II. Worth around €71 million, it is Alstom’s largest third-rail electrification contract in India. Phase II encompasses the extension of Bangalore Metro’s existing North-South and East-West corridors, translating to a substantial increase in the reach of the metro and reduction of road congestion. The scope of the contract includes engineering, supply, installation, testing and commissioning of 750V DC third-rail traction electrification, the construction of 30 33kV/415V auxiliary substations, 26 33kV/750V DC traction substations and a 33kV cable distribution network along the viaduct. Alstom will work on integrating this new infrastructure with the existing system on the Phase I lines, including the augmentation of the SCADA system. The execution of this project will be completed in five phases, with the commissioning of the first 6.5-kilometre stretch expected by the end of 2019. “The significance of our relationship with BMRCL, which goes back to 2009, is underlined by the fact that Bangalore hosts one of Alstom’s most significant sites. Alstom’s footprint in systems and infrastructure is growing rapidly, and this project will give us an opportunity to extend our cutting-edge capabilities and solutions to our customer,” said Alain Spohr, Alstom Managing Director, India & South Asia. Ajay Seth, Managing Director of BMRCL, added: “The new line, once commissioned, will bring in much needed flexibility in the network, while significantly reducing vehicular traffic in the city. It will enable Bengalureans to traverse the length and breadth of the city hassle-free and also add positively to the environmental needs.” 6
Progress Rail Locomotive contract for Bangladesh Railways Progress Rail, a wholly owned subsidiary of Caterpillar Inc., has signed a contract with Bangladesh Railways to supply 40 EMD GT42ACL broad gauge locomotives, equipped with the latest locomotive technology. These will be the first broad gauge locomotives the company has supplied to Bangladesh. Rated at 3,250 braking horsepower with microprocessor control and AC/AC traction, these locomotives will provide; significant fuel efficiency advantages, lower emissions, the latest safety features, as well as notable haulage capacity and reliability. “Progress Rail, through our historic EMD brand, delivered our first meter gauge locomotive to Bangladesh Railways in 1953,” stated Progress Rail Chief Executive Officer Billy Ainsworth. “Since then, we have supplied more than 150 meter gauge locomotives both directly and through partners to the region. We are honoured to be chosen again by the railway to assist in the future growth and development of Bangladesh, this time with an important focus on the broad gauge rail network.” “The 40 broad gauge locomotives will be critical to the growth and improved efficiency of Bangladesh Railways,” Additional Director General, Rolling Stock of Bangladesh Railway Md Shamsuzzaman stated. “Progress Rail has supplied locomotives to Bangladesh Railways for over 60 years and we look forward to working with them on the delivery of these new stateof-the-art locomotives.”

NEWS Malaysia pays Singapore for delayed HSR project It was announced recently that Malaysia has paid S$15 Million to the Singapore government as payment for the deferment of the KL to Singapore HSR Project. Both countries agreed last September to suspend the project for 2 years and the discussions included the payment of this abortive cost to reimburse Singapore. This high profile project was one of the first casualties of the sweeping changes announced after the election of the Barisan Nasioanl (BN) party in May 2018. While the future of this and other major infrastructure projects looked particularly bleak in the early stages of the new administration, the language used to describe their likelihood of completion has become more positive over time. The new HSR line, which will reduce the travel time between the two capitals to just 90 minutes, has been postponed until May 2020, with a completion date rescheduled for the start of 2031.
Combination of Siemens and Alstom prohibited by European Commission One of the railway industry’s most talked about stories during the past year has seen a dramatic development. The European Commission has announced its decision to prohibit the proposed combination of the Siemens and Alstom mobility businesses and as a result of this prohibition, the merger will not proceed. Siemens and Alstom have expressed their regret that the remedies they offered, including recent improvements, have been considered insufficient by the EU Commission. The remedies were extensive in scope and addressed all the concerns raised by the Commission with respect to signalling, as well as very high-speed trains. In addition, a number of credible and well-established European players expressed strong interest in the remedy package, thereby fully confirming its viability. Siemens and Alstom are convinced that the transaction would have created substantial value for the global mobility sector, the European railway industry, customers, travellers and commuters, without harming European competition. It would have also allowed the creation of a European player having the ability to cope with the growing competition from non-EU companies. Commenting on this news, Daniel Desjardins, Senior Vice President, General Counsel & Corporate Secretary, Bombardier Inc, said “We are pleased that the European Commission, backed by the national competition authorities, has prohibited the proposed merger of Siemens and Alstom. This decision is based on the law and facts at hand, after a very thorough 16-month investigation by the Commission. The Commission has been clear that the proposed merger failed to meet the requirements of European Union competition law. It would have severely undermined the health and competitiveness of the whole European rail market, leaving European consumers, both as rail users and taxpayers, to pay the price. The European rail sector leads the world through strong domestic competition, continuous innovation and investment.” Siemens has announced that it will take the time to assess all options for the future of Siemens Mobility and choose the best for its customers, its employees and its shareholders. 8

Wiener Linien discovers new potential for rails in Urban Transportation Systems
By Thomas Hammer, Track Engineering, Wiener Linien Lukas Prettner, Product Management, voestalpine Schienen
W
ith a total track length of 237 km of metro tracks and 427 km of tramway tracks, Wiener Linien in Vienna is one of Europe’s largest Urban Transportation Systems, carrying a total of nearly one Billion passengers per year. Especially in Vienna’s Metro, where the shortest train interval is as low as 2 minutes and maintenance hours are only from 00:30 to 04:00, superstructure components need to fulfill the highest requirements regarding availability and lowest needs for maintenance. Wiener Linien has always had a strong focus on optimizing their Operational Expenditures (OPEX), as well as their Capital Expenditures (CAPEX) by using components offering the longest service lives, combined with the lowest maintenance necessities. Consequently, the performance of products is closely monitored, over time, in the Wiener Linien track database “Gläserner Fahrweg”, which can be translated as “track of glass”. The intention behind the IT-tool „Gläserner Fahrweg“ was to extend the existing infrastructure database towards a viable financial planning tool for track and turnout renewal, which is also the basis for the financial contracts with the city of Vienna. Thus, strategic prognosis models for component degradation, based on long-standing measurement campaigns have been integrated, in order to predict future demands, always aiming to use components with the lowest Life Cycle Costs (LCC). With the aim of further optimizing total LCC, track availability and the maintenance efforts of Wiener Linien’s metro tracks, the voestalpine 400 UHC® HSH® rail steel was recently field-tested on a 700 m long track section in Vienna’s Underground Line U6. The Super Premium rail steel 400 UHC® HSH® is standardized in EN13674-1:2017 as R400HT and positive experiences during Metro Operation have already been collected from all over the world - and have also been demonstrated in [1]. The rail steel combines the benefits of voestalpine’s HSH® special heat treatment technology for steel refining, with an innovative material concept further strengthening the microstructure. It was originally developed in the late 1990s to resist the highest loads of heavy haul transportation and further developed to provide a sustainable solution for urban transportation networks. The testing area in Vienna contained a curve with R = 120 m and a curve with R = 350 m. In the latter, 400 UHC® HSH® was 16
implemented alternatingly with the 350HT HSH® on the high rail and the R260 on the low rail, whereby each section was 45 m in length. The area was closely monitored and a comprehensive inspection program was followed.
Results
The 350 m radius curve, where rails were placed alternatingly, delivered a direct comparison between the aforementioned rail steels. Fig. 1 shows that the side wear of the 400UHC®HSH® (green) rails is reduced by more than 50% on average, compared to 350HT HSH® (yellow) after 2 years in service (approx.. 40 MBGT).
Fig. 1: 45° side wear of the high rail
In order to determine relevant parameters for rail grinding, Head Check depth on the high rail has been measured by Eddy Current technology, allowing a quantitative assessment. Fig. 2 shows that by using 400UHC® HSH® the Head Check Depth was reduced by approx. 50%. Longitudinal profile measurements of the top of the rail surface, each conducted one meter apart from a weld, demonstrate that while corrugation with a depth of 0.24 mm has already developed on R260, 400UHC® HSH® shows only a very slight appearance of corrugation in the range of 0.03 mm (see Fig. 3.)

and thus a conservative approach have been considered for the consideration. Ultimately, the metal removal rates, in combination with natural rail wear on both the High Rail and the Low Rail define the service life of the rails.

Appraisal of results
Corrugation and RCF defects (Head Checks) represent two key drivers for rail grinding or milling. While corrugation is not only one of the most important sources of railway noise, it is the structure-borne vibrations that arise due to corrugation, which ultimately lead to accelerated degradation of other superstructure components. Head Checks, a periodical crack pattern in the gauge corner area, represent a safety critical degradation mechanism that might lead to a multifractal rail break and thus need to be removed as a maintenance action. As former investigations have shown that RCF propagation in early stages tends to be nearly linear [2], the RCF measurement results suggest that at a hypothetical metal removal rate for rail grinding/milling of 0.5 mm is reached for 350HT HSH® after approximately 1.5 years, while the use of 400UHC® HSH® would lead to a grinding/milling interval of nearly three years. Therefore, not only the material removal rate can be reduced by using the 400 UIHC® HSH® steel grade, but also the maintenance intervals can be stretched. Railway operators benefit from the possibility to optimize the maintenance program with a high degree of flexibility, due to the robustness of the rail steel material. As for corrugation, a reduction by a factor of eight was reached after 2 years of service. The reduction of maintenance necessities becomes even more obvious in this case. However, for subsequent study, only Head Checking was taken into account
The Life Cycle Assessment was done by assuming stable annual traffic for the forthcoming years leading to an expected service live of more than 30 years for the 400 UHC® HSH® rails, with the aforementioned benefits in rail maintenance. By taking into account all costs related to rail implementation, rail grinding, or milling and the rail investment itself, the whole Life Cycle Costs were examined on the lowest equivalent annual costs, showing that the savings are in a range of 40 % as seen in Fig. 4. The significant reduction of Life Cycle Costs, by using 400UHC® HSH® rail steel, based on the conservative assumption of not taking into account the big advantage in corrugation, leads to a very stable ranking of results. The ranking of the strategies remains stable against major parameter changes e.g. traffic reduction of 50 %, or major increases in interest rates. Ultimately, the results suggest the use the rail steel 400 UHC® HSH® for the application of High and Low Rails in comparable curves. Due to the savings in maintenance costs for rail grinding, the investment in 400UHC® HSH® amortizes within the first 3 years.
Discovering the full organisatoric and economic potential
Having demonstrated how LCC in a curve were reduced by diminishing wear, along with RCF and corrugation by using 400UHC® HSH®, plus the fact that rail service live is stretched towards more than 30 years, major advantages become obvious: • T he application of 400UHC® HSH® in curves leads to a situation where Total Costs of Ownership of curves are converging to the costs of tangent tracks, where usually standard carbon rails are being used. • The maintenance regimes in these regions are also approximating the maintenance regimes of less stressed areas, which makes maintenance planning easier, by leading to longer sections with similar maintenance needs. These positive effects, observed in Vienna, demonstrate how stateof-the-art technology can be used to reduce costs and facilitate maintenance. [1] L .

The Rise of Digital Twins in Rail
By Meg Davis Senior Product Marketing Manager, Bentley AssetWise
D
igital twins have recently become one of the most talked about topics, because of their promise to leverage innovation to improve design, visually enhance collaboration and increase asset reliability and performance. However, rail is a very traditional and safety-sensitive industry and with the backdrop of owner-operators and project delivery firms needing to work within tighter budgets, shorter deadlines, and increased legislation, change can often be slow and challenging. While the risks associated with changing a tried and tested formula weigh heavily on the minds of those responsible, the upside is that the highly complex nature of rail networks and systems allow for the opportunity to innovate and leverage technology, to change the way rail networks do business. Many owner-operators around the world have recognized the potential for digital twins in their work and have begun to explore the opportunities for applying big data analytics, artificial intelligence (AI), and machine learning (ML) throughout the design, construction, operation and maintenance of rail and transit networks.
What is a Digital Twin?
A digital twin is a digital representation of a physical asset, process, or system, as well as the information that allows us to understand and model its performance. Plainly stated, a digital twin is a highly detailed digital model that is the counterpart (or twin) of a physical asset. That asset might be anything from a ticket machine, or escalator in a station, through track, including the switches and crossings within it, related infrastructure like overbridges, or overhead line structures, right up to and including an entire city. Connected devices and sensors on the physical asset collect data that might relate to the condition or performance of the asset. This data can be mapped onto the ‘digital twin’, to understand how the physical asset is performing in the real world and, through analysis or simulation, how it might perform in the future, or with a different set of parameters.
future products and systems. The relevance and influence of digital twins, which span the entire asset lifecycle, are significant when applied to rail infrastructure. During the planning, design, and construction of a new railway, or major upgrade, project digital twins can enable the optimization of design, in line with operational requirements and reduce the risk of delayed, or nonconformant construction through simulation. Project digital twins can also improve logistics and communication within the supply chain, enabling on-time and within budget completion. Performance digital twins are at their most valuable during operations. Owner-operators gain insight when inputs from Internet of Things (IoT) connected devices, such as drones that deliver continuous surveys to provide real-time tracking of asset changes in real-world conditions, add to the digital representation. This transparency helps owner-operators prioritize and improve maintenance, or upgrades. Consequently, the most significant value a rail or transit system can achieve is through the successful implementation of digital twin technology. By using twins to plan, design, and build the network and utilizing the digital twin during operations, a rail or transit owner-operator will improve performance and reliability. With the application of AI and ML, analytics visibility gained from big data can provide insight and immersive digital operations to enhance the effectiveness of operations and maintenance. In this instance, access to performance digital twins
Why are Digital Twins Important?
Digital twin technology has existed in industries like manufacturing for many years, driving lean processes, improving performance and predicting and highlighting components at risk of failure. Additionally, digital twin technology ensures that the lessons learned contribute to design enhancement and are applied to 19
might enable staff to anticipate and avoid issues, before they arise, or improve reaction times to system failures to reduce downtime. With the application of drones and robots, plus AIbased computer vision, the automation of inspection tasks, via a living digital twin, will enable experts to conduct inspections remotely, vastly increasing productivity, leveraging the value of specialists and reducing the risk of exposing team members to dangerous environments.
Realizing the Potential of Digital Twins
There must be practical solutions for the synchronization of the physical asset’s changing condition to realize the full potential of digital twins. The timing and scope of this synchronization is key, because certain assets update in near real-time, which can be critical to their reliability. For others, a weekly, monthly, or even annual update on condition may be sufficient. Therefore, it is important that the organizations and professionals involved have a clear Maha Metro’s connected data environment (CDE) provides real-time access to trusted information strategy when setting the criteria for synchronization, including which assets should be analyzed, when, and by what delivery and/or better performing assets, every day and all parameters. around the world.

The used in the project’s or asset’s engineering design and organization is committed to a full lifecycle approach and specification. Digital engineering information is like the “digital has deployed a digital project delivery system with OpenRail’s DNA” for infrastructure assets. Just as doctors can analyze connected data environment (CDE) at its core and encompassing human DNA to anticipate health issues and personalize care for every phase of the asset lifecycle from planning to performance. better health outcomes, project delivery firms can harness digital Maha Metro’s CDE is configured to record all data and engineering information to enable collaboration, improve decision uses asset tags to link components created with Bentley’s open making and deliver better project outcomes. modelling applications, with other software, such as its enterprise For owners, leveraging “digital DNA” is all about creating and resource planning system.

Conclusion
It is clear that digital twins are gaining momentum, particularly within organizations that presently have IoT initiatives. The emergent nature of digital twins will require an approach with clear business objectives and an agile approach to experiment and learn from experiences. Just as Maha Metro is setting the agenda and direction for the industry of tomorrow, at Bentley we fully expect to see the use and adoption of digital twins become common place within rail owners and their supply chains in only a few short years.

reduce the weight of the isolation transformer, while increasing its efficiency at the same time. The weight and size of an isolation transformer depends on its operating frequency. The higher the operating frequency, the lower the weight and size of an isolation transformer become. With today’s power electronics technology, operating frequencies of a few 10 kHz are achieved even for power ratings of 150 kVA or more. This reduces the weight of the isolation transformer from a few hundred kilos, to tens of kilos and therefore significantly lowers the static inverter's total weight. Due to the higher operating frequency such static inverters are called medium-frequency static inverters. The first medium-frequency static inverters were introduced in Europe about 15 years ago. The first metro rolling stock in Asia using medium-frequency static inverters were the 3-car trains for Kaohsiung metro made by Siemens, which use 1st generation SMARTconverters designed and manufactured by SMA Railway Technology GmbH of Germany. The units entered revenue service more than 10 years ago.
1st and 2nd generation medium-frequency static inverters Running the isolation transformer at a higher frequency requires a different static inverter configuration. A medium-frequency static inverter typically consists of an input inverter that supplies the isolation transformer with a medium-frequency AC voltage. At the isolation transformer output this medium-frequency AC voltage is rectified and fed into the DC link of the output threephase inverter, which directly supplies the connected loads with the necessary voltage and frequency. 1st and 2nd generation medium-frequency static inverters were about 30 % lighter than conventional static inverters. While the weight reduction could have been bigger, it was necessary to focus on the reliability and maintainability of the equipment. Otherwise, the higher number of electronic components used could have decreased reliability. This would have been

unacceptable to rolling stock operators, despite the higher energy efficiency. As an example, the Alstom Metropolis C830C trains used in Singapore on the Circle Line use 2nd generation SMARTconverters made by SMA Railway. The forced air-cooled units are supplied with 750 V DC from the traction power supply and output a threephase AC voltage of 3 x 400 V AC, 50 Hz, with a rated power of 127 kVA and additionally include a 27 kW, 110 V DC battery charger. This unit weighs about 900 kg and is one of the most reliable static inverters used in Singapore.
Today’s 3rd generation medium-frequency static inverters After ensuring reliability and using the return of experience gained during more than 10 years of revenue service with mediumfrequency static inverters, further reductions in weight, with simultaneous increases in efficiency, became feasible. In 2015, SMA Railway introduced its 3rd generation of medium-frequency
static inverters. Following successful projects in Europe, India and South America, the Klang Valley MRT Line 2 project in Malaysia is the first main application of this improved 3rd generation SMARTconverter in South East Asia. The new unit will be used on the new rolling stock manufactured by Hyundai Rotem for the project. The forced air-cooled units are supplied with 750 V DC from the traction power supply and output a three-phase AC voltage of 3 x 400 V AC, 50 Hz, with a rated power of 155 kVA and additionally include a 25 kW, 110 V DC battery charger. Even though its power rating is 15% higher compared to the 2nd generation SMARTconverter used in Singapore, this unit weighs only about 600 kg. In addition to the reduction in weight, the volume was also reduced by about 30 %. More importantly, the peak efficiency now reaches 95%, which is a reduction in power losses of about 50% compared to a conventional static inverter. This higher efficiency achieves Alstom’s Metropolis for Singapore significant energy cost savings, as the auxiliary systems semiconductors, such as silicon carbide (SiC) devices, which will onboard a metro train consume as much energy as the traction allow new design approaches. system, or even more. As mentioned previously, this is especially The design of a static inverter is always a compromise between true for South East Asia with the air-conditioning system being the the lowest possible weight, highest efficiency and reliability and biggest single load. also the costs. The introduction of medium-frequency static inverters made it possible to decrease weight significantly, The future Advances in power electronics are the key driver in the while increasing efficiency at the same time. The new power semiconductors can now be used to either reduce size and weight development of static inverters with medium-frequency galvanic isolation. The technology is mature and service-proven, further, or to increase efficiency. however, further advances in power electronics will also benefit Today, the size and weight of medium-frequency static inverters are already defined to a high degree by the necessary current static inverters, particularly the introduction of new power conducting capabilities and vehicle interfaces. While a further reduction certainly seems possible, the potential is limited and the effort required is high. Additionally, the small volume of the units already poses a challenge regarding thermal balance. On the other hand, the potential for an increase in efficiency seems promising. The requirements for the next generation of mediumfrequency static inverters are not yet completely clear. Should the size and weight be reduced still further, or is an increase in efficiency a better objective? Perhaps there is no general answer. In any case, further analysis is needed together with the train manufacturers and operators, to provide an answer and further improve railway energy efficiency.

The Challenges for a modern Train Detection System By Jan-André Völkel Sales Manager Product Business, Transportation Systems, Thales Deutschland
A
xle Counters have gained massively in momentum and importance during the last several decades. More and more railway operators have been deciding to use axle counters instead of track circuits on their infrastructure, both for main line and urban rail. The Thales digital Multi Section Axle Counter System Az LM is suitable for train detection in every application. It combines the company’s experience of developing axle counter’s since the 1960s, with the latest technology for safe, secure, reliable and cost efficient train detection. The comprehensive multi-section axle counter Az LM solution is capable of managing almost any train detection application, regardless of the railway segment. There are only a few very reliable systems available in the market – and Thales’s axle counter has proven its superior benefits due to its unique working principle.
counter system enables the transmission of digital telegrams via Ethernet over unlimited distances. Additional benefits include the scalable redundancy of the system.
Cyber secure by design!
As a world leader in cryptographic security products and cutting edge strategies, Thales provides complex safeguard solutions for the transport sector. Cyber security, especially data protection, is of utmost importance in railway signalling. Our railway signalling products are secured in accordance with ISO 27001 and NIST 800-53 security requirements.
Unique design provides a reliable train detection solution The Az LM axle counter is composed of two corresponding wheel sensors, one on each side of the rail. One side is a double rail contact coil for transmitting, while the other side has a double rail contact coil for receiving. Thus, an electro-magnetic field is induced around the rail – and not alongside the rail. When the field is changed in the specific pattern of a steel wheel, only passing wheels (axles) are detected – no other objects such as metal cans, or safety boots are detected. This unique design ensures a very reliable train detection solution. Another benefit of this system is the digital transmission from its outdoor detection points, to the indoor axle counter evaluator. The analogue wheel pulses captured at rail contacts are transferred to an adjacent trackside electronic unit, a few meters out of the danger zone. In the electronic unit, these analogue wheel pulses are translated into a digital count and transmitted by digital telegrams to the axle counter evaluator, several kilometres away. This fault tolerant digital transmission is more reliable than any analogue transmission, as it is more resilient against external influences, such as electromagnetic interferences. The Thales axle

Innovative solutions for seamless train operation The constant availability of the axle counter system is key to seamless train operation and the Az LM solution offers the highest availability by design. But we have taken this further: Axle counter technology in general suffers from the disadvantage that a reset needs to be applied after a section has been disturbed. This puts additional safety responsibility on the operators and the train drivers. The analysis of root causes for 25

section failures shows that the vast majority of section failures are caused by some external influence such as power supply, cabling issues or inadmissible EMI crosstalk from return current, or the rolling stock itself. This means that in almost all cases no maintenance activities are necessary. Nevertheless, such a short term disturbance requires a reset procedure to be initiated, with all the negative consequences. The automated reset functionality of our axle counters, called Meta section solution, brings an immense improvement in
Due to these unique features, benefits and easy adaptability to every kind of different interlocking and application, Thales axle counters are in use worldwide. As anticipated, we have been approached with many technical inquiries requesting support. These queries come from a variety of users and staff categories. We therefore set up a comprehensive certified axle counter training program. The aim is to transfer knowledge to different users of the axle counter product, in order to avoid failures at the earliest possible moment during the different stages of the project life cycle. This training concept covers the complete product implementation cycle and is tailored for every staff category in a modular set-up. Modern tools are used to support the training particularly to explain complex operational rules, such as reset procedures. The feedback from the training participants has been excellent. In addition to this, Thales provides a ”Train the Trainer Program” in order to certify local trainers in collaboration with Thales University. Each certification is valid for two years and can be extended after the expiry date by two years, through attending a refresher course. This ensures that participants who have not worked with the axle counter system for a longer time can refresh their knowledge, without going through the whole course again. Certified participants gain access to Thales myProducts service for additional online support.
Product Training is essential! A scalable and flexible allocation of tasks is key for optimal investment into a train detection system. Engineering, installation, commissioning or maintenance of the axle counter system may be carried out by customers, contractors and railway staff.

In case the reason for this disturbance is no longer active and the counting information from the detection point is available again, the defective sections are automatically recovered by the Central Evaluator, provided the sections are free. The configuration of Meta sections is fully managed and automated by

An inadequate “know-how” level can lead to incorrect maintenance actions, blocking, or failing of the safety system. To support qualified fault finding and rectification by the manufacturer, adequate fault reporting and analysis (recording of events, record of corrective actions and defective parts handling), which is also a key part of a maintenance training, is necessary. Many of our customers worldwide have benefited from this training. The feedback from the training participants has been excellent. Thales incorporates both theory and hands-on practice to ensure that the content is understood and applied correctly.

LIGHTWEIGHT CHAMPION SF02T-FS LINSINGER rail technology - the most modern and cost-efficient way of rail re-profiling. A perfect rail surface finish by rail milling increases ride comfort and directly translates into significant noise reductions. The resultant, defect free rail profile exactly matches the desired target profile without thermal material transformation as often seen with abrasive treatment methods. Additionally, switches and crossings can be treated without removing track components like check rails or wheel counters. www.linsinger.com
