yard is particularly busy in the evening and early morning hours to service and maintain the subway fleet after which the trains are put into position to go into service in the morning. History Prior to construction, most of the yard site used to be a clay quarry that later became Harper's Dump, Toronto's main landfill in the 1930s. The site also contained some residences which were demolished. In May 1965, the Greenwood Yard was put into partial service for some repair work. Heavy maintenance of subway bogies was transferred from the Hillcrest Complex to Greenwood. On February 26, 1966, the yard went into full service with the opening of Line 2 Bloor–Danforth. When it opened, the yard had a railway siding and some four rail, dual gauge ( and ) track for the delivery of subway cars from the manufacturer. However, circa 2013, the TTC removed the standard gauge track to make more room for subway car storage. As of 2016, the standard gauge siding had been severed from both the yard and the railway mainline. Future Plans for the current yard to be used for the Relief Line involved T1 cars being moved to the new Kipling Yard.
