In September 2010, three of the withdrawn Class E31 locomotives (E32 to E34) were transferred to the Ōigawa Railway to replace the ageing E10 and ED500 locomotives used there. Initially they were used only for depot shunting duties, but from 2017 they underwent overhaul in preparation for use as helper locomotives on steam-hauled trains, with the first locomotive treated, E34, scheduled to enter revenue service on 15 October 2017.
