>>1050914>E657That still can't travel the west side of the country either since it is only 20kV AC / 50Hz, which is incompatible with Western Japan's 60Hz grids. And speaking of Hz, it is also interesting to know that after JNR's privatization there are only three dual voltage EMUs that are 50/60Hz compatible (E653, E655, and the E001 for TRAIN SUITE Shiki-shima, all JR East) whereas all other Post-JNR dual voltage EMUs are only compatible with either 50Hz (JR East) or 60Hz (West JR)
50/60Hz electrification is a mistake (even more so than Narrow Gauge)
