Toronto-gauge railways

Railway track gauge (1495 mm)

Toronto-gauge railways are tram and rapid transit lines built to Toronto gauge, a broad gauge of 4 ft 10+7⁄8 in. This is 2+3⁄8 in (60 mm) wider than standard gauge of 4 ft 8+1⁄2 in which is by far the most common track gauge in Canada. The gauge is unique to the Greater Toronto Area and is currently used on the Toronto streetcar system and the Toronto subway, both operated by the Toronto Transit Commission. Several now-defunct interurban rail systems also once used this gauge. The Halton County Radial Railway, a transport museum is located on one of the former interurban lines and uses the Toronto gauge.
