The E531 series (E531系?) is an electric multiple unit (EMU) train type operated by East Japan Railway Company (JR East) in Japan.[1] It was introduced by JR East on 9 July 2005 to replace the aging 403 and 415 series EMUs running on the Jōban Line from Ueno Station in Tokyo. The stock is a dual-voltage (1,500 V DC & 20 kV AC) development of the DC-only E231 series suburban EMU design, and can run at speeds of up to 130 km/h (80 mph) in service.[2]

Operations

Trains are formed in 10-car (set numbers K-401 onward) and 5-car (set numbers K-451 onward) sets. 15-car formations are generally run between Ueno and Tsuchiura. 10- and 5-car sets operate singly north of Tsuchiura, and 5-car sets are used on the Mito Line.

Formations

The E531 series sets are formed as shown below with car 1 (11) at the Ueno end. All sets are based at Katsuta Depot.[3]

History

The first E531 series trains entered service on 9 July 2005.[6]

Pairs of double-deck "Green" (first class) cars were added to the 10-car sets from 6 January 2007, and all 10-car sets included Green cars by the start of the revised timetable on 18 March 2007.

In September 2014, an additional 10-car set, K423, was delivered from the J-TREC factory in Yokohama, four years after construction of the original fleet had ceased.[7] This was followed in December 2014 by a five-car set, K469, also delivered from J-TREC in Yokohama.[8]

Build details

The build details for the fleet as of 1 October 2014 are as shown below.[9]
