The line is solely operated with the TTC's newer Toronto Rocket (TR) subway trains, which are based on Bombardier's Movia family of trains. Unlike other trains in the Toronto subway rolling stock, the TR trains have a "six-car fixed" articulated configuration with full-open gangways, allowing passengers to walk freely from one end to the other.
