Context:
India and Japan have officially announced the deployment of the next-generation E10 Shinkansen bullet trains for the Mumbai–Ahmedabad High-Speed Rail (MAHSR) corridor. The project recently marked a major milestone with the successful completion of the first phase of tunneling for the 21-kilometre undersea section between Bandra Kurla Complex (BKC) and Thane.

About the E10 Shinkansen

What is the E10 Shinkansen?
The E10 Shinkansen represents Japan’s latest advancement in high-speed rail technology, developed to replace the aging E2 and E5 series. It is designed by East Japan Railway Company (JR East) in collaboration with UK-based design firm Tangerine.

Design & Inspiration:

• Inspired by the delicate form of cherry blossom petals.
• Features a sleek aesthetic in “Tsugaru Green” and “Evening Elm” hues.
• The design reflects a harmony of nature and technology, paying tribute to the scenic landscapes of Japan’s Tohoku region.

Key Features:

• L-shaped guides to prevent derailments during earthquakes.
• Lateral dampers and high-performance braking systems to minimize shaking and reduce stopping distances.
• Blowerless induction motor for improved energy efficiency and lower maintenance.
• Built with autonomous operation capabilities, and adaptable space for future cargo transport.
• Comfort-focused interior with a two-seat-per-row layout for enhanced passenger experience.

India–Japan Partnership: Mumbai–Ahmedabad Bullet Train Corridor

• India becomes the first country outside Japan to introduce the E10 Shinkansen.
• A key highlight of the corridor is the 21 km undersea tunnel between BKC and Thane, marking a first in India’s railway history.
• Japan is providing financial support, technology, and rolling stock, while India, through the National High-Speed Rail Corporation Limited (NHSRCL), oversees construction and execution.
• The project is progressing rapidly, with viaducts, stations, and other infrastructure currently under development.
• The entire corridor is expected to be operational by 2030.
