Four locos (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.
They are normally used in pairs top-and-tailing permanent way maintenance trains and to haul newly-delivered rolling stock.
Locomotive number E33 was withdrawn on 31 January 2009, becoming the first of the class to be withdrawn.[1] The remaining three locomotives were withdrawn on 28 March 2010.[2]
In September 2010, three of the withdrawn Class E31 locomotives (E32 - E34) were transferred to the Ōigawa Railway to replace the ageing E10 and ED500 locomotives used there.[3]
Locomotive E31 remains preserved at Seibu's Yokoze Depot.
