Halton County Radial Railway

The Halton County Radial Railway is a working museum of electric streetcars, other railway vehicles, buses and trolleybuses. It is operated by the Ontario Electric Railway Historical Association (OERHA). It is focused primarily on the history of the Toronto Transit Commission (TTC) and its predecessor, the Toronto Transportation Commission, Its collection includes PCC, Peter Witt, CLRV and ALRV, and earlier cars from the Toronto streetcar system as well as G-series and M-series Toronto subway cars.

The museum is open to the public, with rides on many of its vehicles. It is located between the villages of Rockwood and Campbellville in Milton, Ontario, Canada, along part of the Toronto Suburban Railway's former right-of-way. The tracks conform to the TTC's track gauge of 4 ft 10+7⁄8 in (1,495 mm), which is 60 mm (2+3⁄8 in) wider than 1,435 mm (4 ft 8+1⁄2 in) standard gauge. Vehicles from other systems must be altered to accommodate the tracks, and cars intended for third-rail power must be reconfigured for use with overhead wire. In 1889, electric railway service on routes radiating from Toronto, Ontario began. An Ontario Historical Plaque was erected at the Halton County Radial Railway Museum by the province to commemorate the Radial Railways' role in Ontario's heritage. Museum Peter Witt streetcars can be seen in the 2005 film Cinderella Man on the streets of Toronto to give it a 1930s New York City appearance.
