The Davisville Subway Yard is a rail yard on the Toronto Transit Commission's Yonge subway line. The train maintenance and storage building is referred to as the Davisville Carhouse. Location The yard is located adjoining the Davisville station, between and stations. The yard is next to the TTC headquarters in the William McBrien Building at 1900 Yonge Street. History Davisville Yard acted as the main maintenance and storage yard for Toronto's Yonge subway, which opened between Union Station and Eglinton Avenue in 1954. The first two subway cars (5000 and 5001) were delivered to the TTC's Hillcrest Complex, but subsequent subway cars were delivered to Davisville yard via the Toronto Belt Line Railway. Before the opening of the subway, there was a temporary interchange track between the Yonge streetcar line and the Davisville Yard on the north side of the Belt Line bridge for the interchange of rail equipment with the streetcar system. In 1953, subway cars 5000 and 5001, after being displayed at the Canadian National Exhibition, were mounted on shop bogies and towed at night over streetcar tracks by a Peter Witt motor to the Davisville Yard via the temporary interchange. (The two subway cars had arrived at the CNE from Hillcrest via the Bathurst streetcar line. At the CNE, the two cars were displayed on their own bogies.) The Davisville Carhouse could not handle heavy repair work for subway bogies. Thus, until the shops at Greenwood Yard were opened in 1965, bogies needed to be shipped by truck to the Hillcrest Complex on a specially built trailer. According to rail historians John F. Bromley and Jack May, this was the reason that the subway was built to the streetcar gauge of 1495mm, which is the gauge used for shop tracks at Hillcrest. There used to be an upper yard having 2 parallel stub tracks plus a shorter stub siding all running parallel to the former Belt Line Railway line (today the Kay Gardner Beltline Park). Another track, located on an incline, connected the upper and lower yards; today, a short stub siding on the west side of the yard is all that is left of that connecting track. Various pieces of work equipment were stored in the upper yard. Davisville was Toronto's sole subway yard until 1966, when Greenwood Yard opened. Subway car deliveries were also shifted to Greenwood at this time. While usage of it began
