The Taipei Metro VAL 256 is a medium capacity rapid transit EMU operated on the Taipei Metro. The VAL 256 was the first trainset to enter service on the Taipei Metro in 1996 (followed by the C301 trains the following year). VAL 256 cars are capable of driverless operation, as of all other trainsets. It is part of the VAL family of automated rubber-tired trainsets, also incorporating MAGGALY technology used on Lyon Metro Line D, but is larger than most other VAL trainsets (the Chicago O'Hare's Airport Transit System also uses the VAL 256). The 102 cars were built by the Matra conglomerate (with GEC Alsthom) from circa 1990 to 1993, and entered service three years later. Within a year of revenue operations, Matra terminated the service contract, removing all maintenance crew. They filed and won a complaint against the Taipei City Government over contract delay compensations. All the while, the VAL256 trains continued service for twelve years, serviced by TRTC engineers and Academia Sinica researchers.〔(Taipei Metro – Approaches and strategies in managing an extensive and diverse rail framework ), Richard C.L. Chen, TRTS, retrieved 26 April 2008〕 They featured fixed-block ATC/ATO systems for driverless and manual operation,〔http://www.trtc.com.tw/e/future.asp?catid=%E9%97%9C%E6%96%BC%E6%88%91%E5%80%91&small=%E8%B7%AF%E7%B6%B2%E8%88%87%E7%B3%BB%E7%B5%B1#Systems.

This involved building 202 new cars, a new track signaling system (CITYFLO 650), and overhauling the Matra cars to function under the new system.〔(【引用サイトリンク】title=CITYFLO 650 - Neihu LINE, Taiwan )〕 The Bombardier Innovia APM 256 trains were built from 2006 to July 4, 2009.〔 Integration of the Bombardier-built cars with the Matra-built cars was a daunting task, the consequences of which were multiple system malfunctions and failures along the Wenshan and Neihu Lines. Each four-car train is formed by two coupled two-car trainsets. Any two sets can be coupled, and their numbers do not need to be consecutive (unlike the heavy-capacity trains). The VAL 256 train sets have served the Muzha Line since 1996. The trains were taken offline for 17 months for control system upgrades, and resumed service in December 2010.
