History[edit]

Former driving cars with blanked off doors, 2008

30 vehicles were delivered in 1990, formed as five 2-car (NE 101–105) and five 4-car (NE 1–5) sets. These entered service from 1 September 1990 on new Super White Arrow limited express services between Sapporo and Asahikawa.[6] Sets were also used on some Lilac services.[4]

From 18 February 2002, the original 4- and 2-car sets were reformed with the addition of newly built MoHa 784-500 and MoHa 785-500 cars to create a fleet of seven 5-car sets and one spare 2-car set, which was kept in storage.[1] The control equipment from the cabs of cars within sets was removed between 2007 and 2008.[3]

From 1 October 2007, they were reassigned to new Super Kamui limited express services between Sapporo and Asahikawa, and Airport rapid services between Sapporo and New Chitose Airport in conjunction with 789-1000 series EMUs.[6]

The spare 2-car set, NE 105, stored out of use since 2002 was modified in 2010 and repainted with green cab ends for use in conjunction with 789 series sets on Super Hakuchō services from the start of the revised timetable on 4 December 2010. This set has a maximum speed of 140 km/h.[5]
