JR East Develops Next-Generation Tohoku Shinkansen “E10 Series”

JR East is developing the next-generation Tohoku Shinkansen “E10 Series.”

The new train will succeed the E5 series Shinkansen and is scheduled to be completed after the fall of 2027, with trial runs planned before the start of commercial operations in fiscal 2030. The train will have 10 cars with a maximum operating speed of 320 km/h.

The exterior design is primarily green, evoking the mountains of the Tohoku region, and inspired by the natural landscapes along the route. The upper bright green is called “Tsugaru green,” and the lower dark green is “Evening elm.” Curved lines connecting the cars imitate the petals of cherry blossoms, symbolizing Japan while continuing the legacy of previous Shinkansen designs. The design is by London-based tangerine.

The train aims to provide a more comfortable travel experience with expanded luggage space and AC power available at all seats. Car 5 will have a door for luggage transportation, enhancing the flexibility of the “Hakobiyun” service by facilitating easier loading and unloading at intermediate stations.

A service evolved from “TRAIN DESK” will be introduced, with a “2-2” seat arrangement creating more space than the current “TRAIN DESK.” Dividers between seats and side wings will ensure privacy. Tables will be larger, and USB power will also be provided.

Using technology verified on the next-generation Shinkansen testing platform “ALFA-X,” the train aims for greater safety with L-shaped vehicle guides to prevent derailment, reduced braking distances, and lateral dampers to absorb seismic motion, preventing damage and derailment during earthquakes.

The train system will be compatible with “smart maintenance,” and it will be the first Shinkansen operator to use a blower-less induction motor (self-ventilated induction motor) eliminating the need for a cooling motor. High-efficiency SiC (silicon carbide) elements will be adopted for the vehicle drive inverter to improve system efficiency.
