E751 series


The E751 series is an AC electric multiple unit train type operated on Tsugaru limited express services in the north of Japan by East Japan Railway Company since March 2000. The design was based on the earlier E653 series EMUs, with improvements to cope with colder weather conditions in the north of Japan.

History

The first set was delivered to Aomori Depot from Tokyu Car Corporation's Yokohama factory on 9 December 1999, followed by the remaining two sets in January 2000. The fleet entered service on Super Hatsukari services operating between and from the start of the revised timetable on 11 March 2000.
From 1 December 2002, the E751 series trains were reassigned to new Tsugaru services operating between and, which replaced the former Super Hatsukari services following the opening of the Tōhoku Shinkansen extension from Morioka to Hachinohe.
In late 2006, all three sets underwent modifications at JR East's Kōriyama Works to reinforce the front end snowploughs and add protection plates to underfloor equipment.
From the start of 4 December 2010 timetable revision, the E751 series sets were replaced on Tsugaru services by 4-car 485-3000 series EMUs, and were temporarily removed from regular service. From 23 April 2011, the fleet of three E751 series sets were reinstated on Tsugaru services, this time formed as 4-car sets, replacing the 485-3000 series sets. The three pairs of MoHa E751 and MoHa E750 cars removed were stored at Aomori Depot, and occasionally reinserted into sets to provide increased capacity during busy seasons until the three pairs of cars were withdrawn in 2015.
