Braking beyond wheel adhesion
Roof panels add aerodynamic drag, while an experimental linear device brings coils close to the rail to produce electromagnetic retardation. Both were investigated for faster emergency stopping.

Roof panels add aerodynamic drag, while an experimental linear device brings coils close to the rail to produce electromagnetic retardation. Both were investigated for faster emergency stopping.
Heated underfloor panels and reshaped areas around the bogies address snow adhesion and snow-laden airflow. These are experimental provisions described in the 2020 review.

Car 1 keeps an E5-like amount of interior space. Car 10 has a much longer nose, a raised cab and a flatter upper nose profile. JR East compares the shapes to reduce the pressure wave produced when entering a tunnel.
