Operations
editThe locomotives are built at the Toshiba factory in Fuchū, Tokyo. Initially, they were all based at Sendai depot for use on long-distance container trains from the Tokyo area to Hokkaido via the Tohoku Main Line, replacing DC Class EF65s south of Kuroiso, pairs of AC Class ED75s north of Kuroiso, and pairs of AC Class ED79s through the Seikan Tunnel.[1]
In 2004, locomotives EH500-25 and EH500-27 were loaned in turn to Moji depot in Kitakyushu for trials. From 2007, a number of EH500s were transferred to Moji depot for use on 1,300 tonne freight trains between Honshu and Kyushu through the Kanmon Tunnel, replacing ageing AC Class ED76s and dual-voltage EF81-300s and EF81-400s.
As of 1 April 2013[update], the fleet totalled 82 locomotives (EH500-901 and EH500-1 to EH500-81).[3] 12 locomotives, EH500-45 to EH500-50 and EH500-67 to EH500-72, are based at Moji Depot, and the other 70 members of the class are based at Sendai.[4]

EH500-901
editThe prototype, EH500-901, was delivered to Sendai depot in September 1997 for extensive testing on the Tohoku Main Line and Kaikyo Line until March 1999.[2] The livery is red and grey with black cab surrounds.[2] It joined the rest of the Class EH500 fleet for use on revenue services from the start of the March 2000 timetable revision.[2] "Kintaro Eco-Power" logos were added to the sides from December 2002.[2]
