Trends facing rail Sustainable growth
Industry consolidation
Improved customer experience
Trends and drivers
Achieving these competing demands necessitates a step-change in technology, beyond the capability of conventional signalling and control systems. For these reasons, the train control market is increasingly becoming dominated by the introduction of modern Digital Train Control (DTC) systems that include Automatic Train Protection (ATP), Automatic Train Operation (ATO) and Automatic Train Supervision (ATS), such those based around European Train Control System (ETCS) and Communication-Based Train Control (CBTC) technologies. Much like the previous stepchange from mechanical to conventional (electrical) colour-light signalling, the change to data communication-based in-cab signalling and train control results in a significant and fundamental change to the way that railways are operated.
Digitalisation
Automation
Safety and security
Railways across the world are striving to deliver more capacity and reduced journey times, with improved safety and performance (reliability and resilience), and increased sustainability (environmental and financial).
Future workforce
Whole life cost optimisation
Opportunities
Mobility as a service
Opportunities in monitoring and management responds to many global trends and drivers facing rail
The introduction of digital train control is pivotal to delivering a rail service fit for the demands of today and tomorrow.

Spotlight on digital train control
Over 1000 km of fully automated metros have been put in service over the last 35 years.1 CBTC has been implemented at all Grades of Automation. World’s first mainline-passenger with ATO over ETCS was on Thameslink in March 2018. 2 Over 100,000 km of ETCS equipped infrastructure worldwide. PTC is required on 60,000 miles of the US rail network. 1 International Association of Public Transport 204 Unife | GHD | Digital train control

Digital train control systems
We work across all digital train control systems. DTC is dominated by modern signalling control systems such as: – – – –
ETCS: developed to promote mainline interoperability across Europe CBTC: the established concept for high frequency signalling for metros realised through proprietary solutions PTC: to meet the US Rail Safety Improvement Act of 2008 ATMS: to meet Australian Freight and regional needs
We work collaboratively with all current ETCS, CBTC and PTC technology providers ensuring solutions are independent and agnostic. By drawing on experience from major train control programs across the world, GHD helps shape digital railway programs from concept, through to design, delivery, implementation and, operations and maintenance. Spanning mainline passenger, freight, mixed traffic, heavy haul or mass transit, our distinctive DTC services help rail organisations justify the investment in automation.
We identify and address application and integration issues that impact successful automation regardless of the rail technology and context.
Ensuring confidence in digital railway programs Digitalisation allows us to reimagine how primary safety, control and management functions are managed and operated. This can deliver: – – –
Improved train control: cost effectively increase capacity and safety, using automation to smooth flow and improve performance Improved asset management: data collection and analytics that can be leveraged to operate and maintain the assets based on predict and prevent Improved customer information: real-time data to enable targeted and personalised travel information
GHD’s cross-industry experience aids understanding of the integration of technologies with legacy rail signalling and communications infrastructure. By providing application and implementation support we identify and address risks and issues that may be barriers to success.

Cross River Rail ETCS Technical Advisor
Mission Help south-east Queensland achieve its vision for a modern transport system by providing technical expertise for a European Train Control System – critical for safe signalling and train control. Client: Cross River Rail Delivery Authority Location: Brisbane, Queensland Date: 2020 - ongoing
Cross River Rail will transform travel across the whole of South East Queensland, delivering a new 10.2 km rail line and 5.9 km of twin tunnels running under the Brisbane River and CBD, with four new underground and two above ground stations. It will also rebuild six suburban stations, construct three new Gold Coast stations, upgrade two train stabling facilities, and install a new world-class signalling system. GHD has been engaged to provide technical and strategic support to the Delivery Authority’s ETCS project team to ensure the design developed by Hitachi Rail complies with the Scope & Performance Requirements (SPR) as well as all relevant technical specifications and standards. ETCS is a well-proven signalling system, in use in cities around the world. The Delivery Authority has selected ETCS Level 2 to be deployed as part of the project. Implementation is expected to provide the following benefits: – – – – –
Increased capacity and enhanced safety on the rail network Capable of more accurate information for passengers Improved reliability with more centralised technology and fewer assets required in the rail corridor Technology to support safe track side maintenance Real-time speed profiles and signalling data displayed to driver
Delivering a project of this scale requires careful review and alignment of all documented requirements associated with the project. In early 2020 the Delivery Authority sought to align the system requirements across the ETCS contract, the Rail, Integration and Systems (RIS) alliance and the Tunnel, Stations and Development public-private partnership. We undertook a review of the requirements across the three contractual documents. Drawing on our international experience and expertise we were able to recommend a more appropriate approach to the Delivery Authority. Our ‘real-world’ experience from European and Australian DTC systems has been key to resolving issues quickly and effectively, and to progress the project in a positive way.

Due to the size of the project and to leverage the best outcomes from limited specialist resources, we have focused on the key areas and used a risk management approach to provide targeted advice, which best meets the combined aims of achieving a safe operational ETCS system within a constrained program and budget. Importantly, we are working in close collaboration with the Delivery Authority to provide technical advice on project elements including: – – – – – – – – – – – –
ETCS and conventional signalling Telecommunications Interoperability Traffic management systems Business readiness Rolling stock and train fitment Test room/systems integration Human factors RAM Cyber security Systems engineering Systems assurance
The impact Given ETCS Level 2 is not currently in revenue service within Australia, our team has been integral to the successful first integration of the system into the operational environment for this project. Our understanding of the technical solution and integration with existing brownfield network will be key to the successful deployment for Queensland Rail. Our focus has been to provide strategic technical support relating to the application of a 'systems integration' approach to ensure that the overall, integrated ETCS solution can be delivered in the most cost-effective manner possible. We have also provided the Delivery Authority with strategic technical support in the form of: – – – –
Resolutions for issues where decisions relate to interdependencies between systems and subsystems 'Best for project' outcomes Implementation of lessons learned from worldwide ETCS (and other equivalent digital train control) projects Navigating the changing regulatory environment around critical infrastructure and how the Delivery Authority can deal with emerging challenges of technology implementation.
