India and Japan finalise Rolling Stock design for Mumbai-Ahmedabad Bullet Train Project

New Delhi, India (Metro Rail Today):  India and Japan have successfully resolved key design adjustments for the Mumbai-Ahmedabad bullet train project, marking a significant milestone in developing the country’s first high-speed rail corridor. Senior officials confirmed that the design changes, which address India’s unique environmental and logistical challenges, are expected to receive formal approval in the coming weeks.

Customizing the Bullet Train for Indian Conditions

The changes come after extensive discussions on making the bullet trains better suited to India’s diverse climate and population needs. Key adjustments include:

• Enhanced Load-Bearing Capacity: The trains will be designed to handle heavier loads, particularly to accommodate the needs of the larger Indian physique compared to other Asian populations.
• Larger Luggage Compartments: The new design will incorporate increased luggage space to cater to frequent travelers and long-distance commuters.
• Adaptability to Extreme Temperatures: Given India’s extreme weather conditions, where temperatures can soar above 50°C in some regions, the bullet trains will be engineered to perform efficiently even in these harsh environments.
• Dust-Resistant Design: The trains will be built to withstand dustier conditions, which are common across large parts of India, particularly in rural and semi-urban areas.

Furthermore, officials indicated that seating arrangements may also undergo minor revisions, possibly reducing the number of seats in certain configurations to optimize space and comfort.

The Mumbai-Ahmedabad High-Speed Rail Corridor: Project Overview

The Mumbai-Ahmedabad High-Speed Rail Corridor (MAHSR) is a ₹1.08 lakh crore ($13 billion) mega project that was approved by the Indian Cabinet in December 2015. The ambitious plan aims to cut travel time between Mumbai and Ahmedabad to just two hours and seven minutes. Once operational, the bullet train will travel at speeds of up to 300 km/h, making it one of the fastest trains in India.

The project will connect key stations in Maharashtra and Gujarat, including BKC, Thane, Virar, Boisar, Vapi, Bilimora, Surat, Bharuch, Vadodara, and Anand, with the terminals in BKC (Mumbai) and Sabarmati (Ahmedabad) serving as major hubs. The government aims to boost regional connectivity, reduce travel time, and significantly enhance passenger convenience.

The National High-Speed Rail Corporation Ltd (NHSRCL), a joint venture between the Union government, Gujarat, and Maharashtra, is leading the execution of the project. The Union government holds a 50% stake, with Gujarat and Maharashtra each owning 25%.

Financial Backing from Japan

A substantial portion of the project’s funding comes from Japan, with 81% of the ₹1.08 lakh crore project cost financed through a soft loan from the Japan International Cooperation Agency (JICA). The loan has an extremely favorable interest rate of 0.1%, with a repayment period of 35 years after a 15-year moratorium. The partnership between India and Japan exemplifies strong bilateral cooperation, with Japan’s advanced rail technology playing a pivotal role in making India’s high-speed rail dream a reality.

Addressing Cost Challenges and Design Delays

While the project has progressed significantly, a second official familiar with the developments acknowledged that recent political changes in Japan led to some delays in finalizing the design revisions. However, with the changes now approved, the project is expected to move ahead swiftly, albeit with careful attention to keeping costs under control.

“Yes, we did request design changes to ensure the Bullet Train suits Indian conditions,” the official confirmed. “The changes have been cleared, and formal approvals are expected shortly. We are committed to minimizing cost overruns due to redesign and other factors.”

Japanese Companies to Lead Development

The Kawasaki-Hitachi Consortium, comprising two major Japanese manufacturers, will handle the development, manufacture, and supply of the high-speed trains for this corridor. However, as per the initial terms of the JICA loan agreement, at least one batch of bullet trains must be sourced from Japan.

India’s Vision for Indigenous Bullet Trains

While the collaboration with Japan takes center stage, India is also working towards developing its indigenous high-speed trains. Indian Railways has tasked the Integral Coach Factory (ICF) with producing bullet trains based on the Vande Bharat platform. The new trains will have a top speed of 250-280 km/h, making them ideal for medium to long-distance travel.

As part of the initiative to develop "Make in India" high-speed trains, the BEML (Bharat Earth Movers Limited) has been entrusted with manufacturing the trains for a contract worth ₹866.87 crore. This contract covers design, development, non-recurring charges, and the creation of testing and tooling facilities.

A Game-Changer for Indian Railways

The successful finalization of the design changes for the Mumbai-Ahmedabad bullet train is a crucial step towards revolutionizing India’s transportation infrastructure. This high-speed rail project is set to bring about faster travel, greater convenience, and enhanced connectivity between two of India’s most vibrant cities, Mumbai and Ahmedabad. With the support of Japan’s cutting-edge rail technology and India’s growing capabilities in rail manufacturing, the project is poised to transform India’s rail network and set the stage for more such corridors across the country.

As the bullet train moves closer to reality, it is expected to serve as a model for high-speed rail development in India, improving the nation’s transportation landscape for generations to come.
