==History== [[File:JR hokkaido ED76 522.jpg|thumb|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]].<ref name="railfan615">{{cite magazine| script-title=ja: 電化目前の学園都市線と専用気動車のこと|trans-title=Gakuentoshi Line and its dedicated DMUs ahead of electrification|magazine=[[Japan Railfan Magazine]] | volume = 52| issue = 615|pages=24–27| publisher = Koyusha Co., Ltd.| location = Japan |language= ja| date = July 2012}}</ref> 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 Station (Hokkaido)|Kushiro Depot]], [[Goryokaku Station|Goryokaku Depot]], and [[Naebo Station|Naebo Works]].<ref name="railfan615"/>
