Seibu Class E31

what is it?

The Class E31 (E31形) is a class of DC Bo-Bo wheel arrangement electric locomotives formerly operated by the private railway operator Seibu Railway in Japan until March 2010 and subsequently by the Ōigawa Railway. Four locomotives (numbered E31 to E34) were built at Seibu's Tokorozawa factory between 1986 and 1987 to replace ageing first-generation electric locomotives on freight services and track maintenance train duties. The DT-20A bogies were reused from former JNR 80 series EMUs, and the traction motors were modified from former EMU motors.
