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.
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. 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. The trains have a maximum speed of 110 km/h (70 mph).
E129 series trains operate on the following lines, completely replacing older 115 series sets by around 2017.
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.
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.
The two-car sets, A1 to A30, consist of two motored cars, each with one powered bogie, and are formed as shown below.
The four-car sets, B1 to B25, consist of four motored cars, each with one powered bogie, and are formed as shown below.
