to wane, it remained active even as the larger Wilson Yard opened in 1978. The yard became deactivated after 1993, when repairs were required to a retaining wall to the south of the yard. Even after this work was completed, the yard remained inactive as the TTC had become quite satisfied with the temporary storage and maintenance arrangement during the closure. The yard was temporarily reactivated during the 1995 Russell Hill subway accident, and also during the retirement of older rolling stock (H-1/H-2, M-1). The subway yard was formally reactivated in June 2002, a few months prior to the opening of Line 4 Sheppard. In November 2018, the TTC completed the extension the carhouse over tracks 3 and 4 on the east side of the building. Track 3 is the wash track and track 4 is utilized for interior cleaning and floor washing of the vehicles. Before the extension, tracks 3 and 4 were long enough for only four-car trains within the carhouse building, and the overhead doors on the north and south end had to remain open to service six-car TR trains. The open doors also exposed equipment to freezing in winter. With the extension, the TTC can use tracks 3 and 4 for the overnight storage of six-car TR trains. Current operations Davisville Yard is home to a small portion of the TTC's revenue rolling stock of Toronto Rocket subway trains which operate on Line 1 Yonge-University and Line 4 Sheppard and some of the Commission's work cars. The facility is used to store, service and maintain subway cars. The yard can dispatch 12 trains onto Line 1, and this minimizes the need to deadhead trains from the Wilson Yard. In addition to exterior storage tracks, the yard's carhouse has 8 tracks to perform safety inspections, unscheduled repairs, floor washing and exterior washing. Many Subway Infrastructure sections including Track, Structures, and Signals are also based at the Davisville Yard. Future In 2022, the city of Toronto was studying a proposal to deck over the Davisville Yard in order to build a park over the yard. The yard, the adjacent subway station, a substation and signal facility would remain in operation during construction. The city owns the Davisville Yard.
