E10 Series Shinkansen

The E10 series () is a Japanese Shinkansen high-speed train type on order by East Japan Railway Company (JR East) for use on services. It will also be used on the Mumbai-Ahmedabad high speed rail corridor in India.

Overview

Details of the new trains on order were announced by JR East on 4 March 2025. Scheduled for an introduction into service on the in fiscal 2030, the trains are planned to replace the E2 and E5 series fleets.

The safety technology incorporated in the trains will be derived from the experimental ALFA-X train. To protect against earthquake damage, L-shaped guides are installed on the cars to prevent derailment, dampers are installed to dampen the left-right swaying of the cars caused by earthquakes, and the stopping distance is reduced by 15% due to the improved performance of the brakes. The cars will be designed in anticipation of the introduction of automatic operation in the future and will be built to handle large amounts of digital data for efficient maintenance and inspection of the cars. To improve the efficiency of the propulsion system, silicon carbide elements will be used in the propulsion inverters, and induction motors that do not require cooling will be used for the first time on a commercial Shinkansen train.

The "Gran Class", the highest class of passenger cabin introduced in the E5 series, will be eliminated, and the E10 series will introduce a more advanced version of the "Train Desk", convenient for business travelers to use their laptops. Wi-Fi routers will be added in the cars to improve the communication environment, and the seating arrangement in the cars will be 2+2 seats per row, making the seats wider. In addition, each seat will have a larger folding desk, power outlet and USB port, and partitions will be installed between the seats. A special luggage door will be installed on Car No. 5 to enhance the convenience of the "Hakobyun" luggage transport service.

The 360 km/h commercial operation demonstrated by ALFA-X has been postponed since the extension of the Hokkaido Shinkansen to Sapporo was postponed to the late 2030s due to delays in tunneling work, and the commercial operation speed of the E10 series is 320 km/h, the same as the E5 series. JR East announced that it would consider building new Shinkansen trains based on the E10 series for trains to be put into service when the Hokkaido Shinkansen line is extended to Sapporo.

Export to India

The Japanese and Indian governments are to adopt the train simultaneously, with the train type also seeing use on the under-construction Mumbai-Ahmedabad high speed rail corridor. The inter-governmental agreement initially specified India would purchase E5 series trains, however due to rising costs and postponements in their delivery, India moved to considering domestically produced trains. To break the deadlock in negotiations, the Japanese government offered to gift an E5 and E3 train set, to aid the line's commissioning in 2026 and to offer the E10 series for service entry in 2030. The inspection trains are to collect data to aid possible future production of E10 trains in India. These initial trains would see parallel use with planned train sets, developed by India’s Integral Coach Factory, in collaboration with BEML, designed to operate in service at , for use when the line partially opens for revenue service in 2027.

Design

The E10 series' design was overseen by British design firm, Tangerine, the first overseas designer contracted by JR East for its rolling stock.

Externally, the E10 series trains will be finished in a livery of "Tsugaru" (津軽) green and "Evening elm" (イブニングエルム) green that evokes the mountains of Tōhoku region.
