The Taiwan Railway EMU100 series was a set of rail cars fabricated by British Rail Engineering Limited and the General Electric Company in 1976 that has operated in Taiwan. The alternating current electric multiple unit (EMU) fleet entered full squadron service in 1979, and was withdrawn from service in 2009. This class of railcars were the first to operate on the electric Tzu-Chiang Express. Due to the unit's British origin, rail buffs have variously nicknamed them "British Girl", "British Lady", or "British Grandma".

The EMU1200 series is a series of electric multiple unit passenger trains operated by Taiwan Railways Administration (TRA). The train was originally known as the EMU200 series until all of its cars were refurbished between 2002 and 2004. It is one of the trains that are used for the Tze-Chiang Limited Express.
