what is it?
The S series was the light metro rolling stock used on Line 3 Scarborough, part of the subway system of Toronto, Ontario, Canada. They were built from 1983 to 1986 for the Toronto Transit Commission (TTC) by the Urban Transportation Development Corporation (UTDC) in Millhaven, Ontario. The trains use UTDC's proprietary linear motor-based Intermediate Capacity Transit System (ICTS, now branded as Bombardier Innovia Metro) and are its Mark I model, which is also used by the Vancouver SkyTrain and the Detroit People Mover.
