Interior
Passenger accommodation consists of longitudinal bench seating at the ends, and 2+2 abreast transverse reversible seating in the centre of the cars. The first two batches of cars (KuMoHa 125-1–12) were delivered with 1+2 abreast seating, but this was increased to 2+2 seating during 2003 and 2004.
History
The first eight cars (KuMoHa 125-1–8) were built by Kawasaki Heavy Industries in December 2002 for entry into service from 15 March 2003 on the then-newly electrified 84.3 km on Obama Line between Tsuruga x and Higashi-Maizuru x. These sets were initially allocated to Fukuchiyama Depot, but were subsequently transferred to Tsuruga Depot.
Four more cars (KuMoHa 125-9–12) were built in September 2004 for entry into service from 19 December 2004 on the newly electrified 48.5 km on Kakogawa Line between Kakogawa x and Tanikawa x.
A further six cars (KuMoHa 125-13–18) were built in September 2006 to coincide with the conversion of Tsuruga area services from 20 kV AC to 1,500 V DC electrification from 21 October 2006.
