Although the expansion of the portion of the OU main line between Fukushima and Yamagata was ( conventional rail network) widened the track width of Cape gauge to standard gauge, but the gauge was unchanged, so that the existing, broader Shinkansen trains could not be used.

Due to the time necessary for the mini - Shinkansen narrower loading gauge trains of the series were 400 equipped with a fold-out stage at the doors, which was extended when the vehicle stops at all stations of Tohoku Shinkansen.

Due to the rapidly increasing demand, a seventh car was in 1995 in the original six-car long trains added ( car 15).
