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
[edit]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 (68 mph).[1]
