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.

加热式车底面板及转向架周围重新设计的形状,用于应对积雪附着和含雪气流。这些属于2020年技术报告介绍的试验性措施。
原创侧面示意图。为便于比较,两端均朝左。长度比例为16:22,曲线与高度经过简化。
1号车保留了与E5相近的车内空间。10号车的车头明显更长,驾驶室更高,车头上部轮廓更平缓。JR东日本比较这两种形状,以减小进入隧道时产生的压力波。
