Line 3 Scarborough, originally known as Scarborough RT (SRT), was a light rapid transit line that was part of the Toronto subway system in Toronto, Ontario, Canada. The line ran entirely within the eastern district of Scarborough, encompassing six stations and 6.4 kilometres (4.0 mi) of mostly elevated track. It connected with Line 2 Bloor–Danforth at its southwestern terminus, Kennedy, and terminated in the northeast at McCowan. Until its closure in July 2023, the system had a ridership of 3,908,000.

Medium-capacity rail system
A medium-capacity system (MCS), also known as light rapid transit or light metro, is a rail transport system with a capacity greater than light rail, but less than typical heavy-rail rapid transit. MCS's trains are usually 1–4 cars. Most medium-capacity rail systems are automated or use light rail type vehicles.
