Abstract Operating more than 20,000 trains a day, Indian Railways is the third biggest railway network in the world and a key driver of the country’s economic development. However, increasing competition from alternative modes of transport, primarily road, has resulted in substantial loss of revenue for this national transporter. Rise in the number of rail accidents is also a major concern. To improve passenger experience, safety, and overall efficiency of the railways, it is crucial to incorporate superior engineering technologies and modernize assets that have become redundant over the years.

Indian Railways (IR) is the third largest railway network in the world with 7,2161 railway stations; 1,33,1602 railway bridges; 11,1223 locomotives; 68,8364 passenger coaches; 251,2565 freight cars; and 66,6876 route kilometers. Today IR operates more than 20,000 trains each day, comprising 12,6177 passenger trains and 7,4218 freight trains. In 2016-17, it transported 1,107.1 million tons9 of freight traffic and 8,219 million passengers10.

Indian Railways currently employs 1.331 million people11 and posted an annual revenue base of INR 158.8 billion12 as of March 2017. IR’s vision is to be the key driver of India’s economic growth story by becoming financially more viable, environmentally friendly, and increasingly focused on achieving excellence in passenger safety and experience.

In recent years, however, there has been a disproportionate diversion of freight and passenger traffic to other modes of transportation, primarily road. This has caused a substantial loss in revenue to IR and has also

01

imposed a heavy burden on the country, which is measurable in terms of a much larger freight cost to GDP ratio and higher environmental cost per route km of freight and passenger traffic as compared to other countries. There is an undeniable and urgent need to enhance capacity and modernize Indian Railways to meet the country’s social and economic aspirations of the 21st century.

With modernization and restoration of balance in the intermodal transport mix, railways can be a significant engine of inclusive growth and development for the country. IR will then create more jobs, save energy, and conserve the environment while moving people, raw materials, and goods more efficiently across the country. Highly critical industrial inputs such as coal, which contributes nearly 45% to IR’s freight traffic, will get the much-needed special attention as a modernized railway system will focus on efficient and effective evacuation, movement, and delivery of coal or other important goods.

Capacity Enhancement for Future-Ready Railway Systems The rail transportation industry is an instrumental player in providing logistical support and moving products along the supply chain. However, key market trends such as demand for product individualization, shift from heavy bulk commodities to lightweight products, and smaller consignments of high-value goods are impacting overall business. There is an urgent need to improve the overall efficiency of rail transportation to keep pace with the market dynamics and provide sustainable logistics.

Optimization of one key resource—the rail freight wagon—through innovative design and use can help rail freighters achieve substantial economic efficiencies and growth.

Heavy investments, privatization, and emerging trends are reshaping industries, making them more competitive and demanding. To move goods faster and more efficiently, freight operators need to improve process and freight efficiency. A global strategic partner with relevant domain expertise can help drive significant efficiencies by introducing viable freight and operational best practices.

Challenges: Factors Disrupting Fleet Optimization and Efficiency Freight companies are under severe pressure to move goods quickly, efficiently, and at minimal costs. This in turn has increased the pressure on freight operators to innovate and come up with new means and methods to improve fleet efficiency. However, factors such as lack of visibility into failure data and uncertainty are making it difficult to predict the reliability of components, resulting in the needless accumulation of spares/inventories. The aging rolling stock equipment is proving to be a major setback for fleet operations, impacting operational efficiencies significantly. The resulting high inventory costs are restricting the ability of freight operators to invest capital in new and futuristic products and equipment that can optimize fleet productivity and costs.

To address these challenges and achieve business objectives, use of tools and technologies such as reliability predictions and failure projections for accurate inventory planning is critical.

Overcoming the Challenges Most of the containers and wagons used by freight operators today are obsolete and dated, which makes a time-consuming process, reducing efficiencies and profitability.

It is essential to upgrade or replace existing containers and wagons to overcome this challenge.

Product engineering solutions from experienced partners can help freight operators in several ways. For instance, a partner with deep domain expertise can help analyze the existing rolling stock and suggest modifications for enhancing material handling capabilities. Design re-engineering can increase carrying capacity of the current wagons and containers, thus, optimizing usage. Additionally, advancements in metallurgy and composites have opened up new avenues for innovation.

These advanced materials can be used to build wagons, containers, and coaches that are lighter and more efficient. Lighter rolling stock helps in reducing the carbon footprint by increasing fuel efficiency of the locomotive.
