The E129 series (E129系) is a DC electric multiple unit (EMU) train type operated by East Japan Railway Company (JR East) on local services in the Niigata area since 6 December 2014.

Design

Built at the J-TREC factory in Niitsu, Niigata, the stainless steel body and "universal design" interior is derived from the E233 series commuter EMU.[1] Externally, trains are finished in a livery with "golden yellow" (黄金イエロー) and "toki pink" (朱鷺ピンク) stripes.[1] The trains have a maximum speed of 110 km/h (70 mph).[1]

Operations

E129 series trains operate on the following lines,[2] completely replacing older 115 series sets by around 2017.[3][4]

The E129 series trains can operated in multiple, to form 2+2, 2+4, and 2+2+2 formations, but will not operate in multiple with E127 series trains except in emergencies.[1]

Fleet

The E129 series fleet will ultimately consist of 30 two-car sets (60 vehicles) numbered A1 to A30 and 25 four-car sets (100 vehicles) numbered B1 to B25, all based at Niigata Depot.[1]

Passenger accommodation consists of a mix of transverse seating bays and longitudinal bench seating.[1] LED lighting is used throughout.[1] Longitudinal seats have a width of 460 mm (1 ft 6 in) per person, 10 mm wider than for the earlier E127 series trains, and the seating pitch for transverse seating bays is 540 mm (1 ft 9 in), approximately 110 mm wider that E233 series trains.[1] Floor height is 1,130 mm (3 ft 8 in), the same as for E127 series trains, and lower than the 1,225 mm (4 ft 0.2 in) floor height of 115 series trains.[1]
