Seibu Railway
[edit]
The first 401 series train was constructed in 1968, then known as 411 series. At the time before conversion. 411 series cars had the MT15E traction motors, in later years Seibu converted all 411 series cars to Seibu 401 series. MT15E traction motors were replaced with MT46-based Hitachi resistor-controlled motors. The last remaining trains were withdrawn in 1997.
Sangi Railway
[edit]
401 series train sets were transferred to Sangi Railway in 1990. Among other Seibu EMUs sent to that railway, it's the only 2-car EMU series on Sangi Railway line.
Ohmi Railway
