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]
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]
As of 8 March 2022,[update] the E129 series fleet consists of 34 two-car sets (68 vehicles) numbered A1 to A34 and 27 four-car sets (108 vehicles) numbered B1 to B27. All sets are based at Niigata Depot.[1]
The two-car sets, A1 to A32, consist of two motored cars, each with one powered bogie, and are formed as shown below.[1]
