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 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.
