History
A train of JR Hokkaido 50 series coaches in 1990

A large number of locomotive-hauled 50 series coaches became surplus to requirements following electrification of lines in the Sapporo area of Hokkaido in the late 1980s. A program was therefore started to rebuild a number of these coaches into diesel multiple unit (DMU) trains to replace ageing DMUs on the non-electrified Sassho Line.[3] In March 1990, one two-car set, formed of KiHa 141-1 and KiHa 142-1, was formed at Kushiro Depot and transferred to Naebo Depot from April of that year. Between 1990 and 1995, a total of 44 DMUs cars were built from former 50 series coaches at Kushiro Depot, Goryokaku Depot, and Naebo Works.[3]

Withdrawals and resale

The first two cars built, KiHa 141-1 and KiHa 142-1, were withdrawn in March 2005.[3]

Four KiHa 141 series cars, KiHa 143-155, KiSaHa 144-103, KiSaHa 144-101, and KiHa 142-201, were sold to JR East and moved to Koriyama Works in November 2012 for conversion into the SL Ginga Joyful Train set for use with the restored JNR Class C58 steam locomotive C58 239 from April 2014.[4][5]

A number of cars were sold to Myanmar National Railways.
