GO Transit operates an urban rail network, commonly referred to as the GO train, throughout the Greater Toronto and Hamilton Area (GTHA) and the Greater Golden Horseshoe region of Ontario. Described as both a commuter rail and regional rail system, it comprises seven lines and 71 stations, converging at Union Station in Toronto. In 2025, the system had a ridership of 60,760,200 passengers per year.

GO Transit started on May 23, 1967, running single-deck trains powered by diesel locomotives in push-pull configuration on a single rail line along Lake Ontario's shoreline. When GO trains began operation, they ran on tracks mostly owned by the two major freight railways of Canada: Canadian National and Canadian Pacific. Over time, GO Transit (and subsequently Metrolinx) have acquired tracks, ensuring GO Transit has control over track maintenance and expansion. Metrolinx currently owns 80% of the GO's rail corridors.

All GO Transit fares are calculated by the fare zones that the origin and destination of the trip are in, as well as by passenger category (adult, student, senior or child). GO train fares are not differentiated based whether or not buses are used for part of the trip. The GO Transit rail fleet consists of 90 MPI MP40 locomotives and 979 Bombardier BiLevel Coaches.
