Toronto subway rolling stock
The Toronto subway system's rolling stock consists of 880 subway cars for Line 1 Yonge–University, Line 2 Bloor–Danforth, and Line 4 Sheppard. The rolling stock is owned and maintained by the Toronto Transit Commission.
Subway trains
All active Toronto Transit Commission subway cars are equipped with flip-up seats located in each car, which can accommodate mobility devices such as wheelchairs, strollers, scooters, and bicycles. The new Toronto Rocket trains have two designated areas in each car with automatic flip-up seats, and high-level platforms allow access to all cars.Toronto Rocket
the Toronto Rocket is the newest version of TTC subway trains and operate on Lines 1 and 4. Its design differs from its predecessors, which were formed by coupling sets of married pairs of identical cars. The trains consist of six cars for Line 1 and four cars for Line 4, both of which are connected with open gangways, similar to Bombardier's Movia family of metro trains. They only have two full-width operator cabs per trainset, greater accessibility options and the skin of the train is welded rather than the previously used riveting method. The TRs' exterior front and rear destination and train run number signs are outfitted with digital orange LED boards, while all previous TTC train models use back-lit roller signs.The first of the new TR trains was scheduled to be delivered in late 2009, but in early 2010, TTC officials stated that the new trains would not enter service until late 2010. The first train arrived on TTC property in October 2010, and entered revenue service on July 21, 2011.
Next-generation cars
By 2022, the TTC had decided that the next generation of subway cars would have a design different from the T1 and TR fleets. Like the TR fleet, riders would be able to walk the full length of the interior of the new trains. Like the T1 trains and unlike the TR fleet, the new trains would consist of three coupled pairs. Only the two end cars of the new trains would have cabs; cab-less cars would have hostler controls to allow the independent movement of cab-less pairs within workshop areas.In April 2024, a TTC staff report recommended ordering 80 new trains, 55 to replace the T1 fleet on Line 2 and 25 for Line 1. The estimated cost of the new trains was at $3.23billion with the earliest delivery being in 2030, four years after the lifespan of the T1 fleet.
In July 2024, TTC CEO Rick Leary reported that the TTC would launch procurement for 70 new trains, pending funding from the federal government.
By March 2025, the federal government had signed an agreement for $2.3 billion in funding for the new trains. In August 2025, it was announced that the competitive procurement process which had been underway had been cancelled and that all new trains would be built at the Alstom Thunder Bay plant in a single-sourced contract. The decision was made to keep most of the work to build the new trains in Canada in the face of U.S. tariffs and economic uncertainty. All three levels of government agreed to equally share the cost of the Alstom contract, which would be subject to an independent cost estimate. The initial order was for 70 trains: 55 to replace the T-1 fleet plus 15 to support the Scarborough extension on Line 2 and the Yonge North extension on Line 1, with the option to procure more trains from Alstom in the future.

Work vehicles
Work vehicles are used for infrastructure maintenance within the subway. Most work vehicles are painted yellow, with the exception of retired passenger cars, which retain their natural aluminum exterior with added yellow accents.Track gauge
