The Bombardier INNOVIA APM 256 (sometimes referred as the Taipei Metro CITYFLO650 by its control system, and internally code-named C370 or BT370 by the operational arm of Taipei Metro, Taipei Rapid Transit Corporation) is the second generation of automated guideway transit rolling stock to be used on Wenhu line (Brown Line) of the Taipei Metro. They are distinguished from their predecessors, Matra VAL256, by their circular front headlights and a grey livery, with a green stripe above. Also, instead of yellow forward-facing seats, the train offers blue seats that face inward.

A total of 101 2-car train sets were purchased and produced, for a total of 202 cars.^[2] The sets are numbered from 101 to 201, with both cars in a set receiving the same numbers. They were originally numbered from 52 to 152, continuing the sequence from the first-generation Matra-made sets, but in order to distinguish between the newer and older trains, they were renumbered from 101 onwards.

In May 2015, the Chicago O'Hare Airport Transit System (ATS) awarded Bombardier with a contract to supply 36 Innovia APM 256 vehicles, replacing all VAL 256 vehicles currently in service.^[3] The ATS was initially shut down for complete overhaul on 8 January 2019 and was expected to open in Autumn 2019, however this was since delayed^[4] to 3 November 2021.^[1]
