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

Operations in Niigata area

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 do not operate in multiple with E127 series trains except in emergencies.[1]

Fleet

The E129 series fleet will ultimately consist of 32 two-car sets (64 vehicles) numbered A1 to A30 and 26 four-car sets (104 vehicles) numbered B1 to B26, all based at Niigata Depot.[1]
