Greenwood is one of two subway yards on Line 2, the other being the much smaller Keele Subway Yard.
Spanning 31 acres (13 ha), the Greenwood Yard is located at 400 Greenwood Avenue, on the west side of Greenwood south of Danforth Avenue. The site is bordered on the west, south and east sides by residential areas, and on the south side by a railway line.
The yard contains 5 buildings, two of which are the General Overhaul and Repair Shop (a.k.a. Greenwood Shop) with a floor space of 185,000 square feet (17,200 m2), and the carhouse for inspection, minor repairs and washing. The Greenwood Shop has specialized shops for heavy overhauls of subway cars and components as well as stores. The Greenwood Shop is operationally separate from the carhouse servicing the Bloor–Danforth subway fleet.
The Greenwood Yard is connected to the Bloor–Danforth line by a multi-level wye between Donlands and Greenwood stations; the wye allows both east and westbound mainline trains access to the yard. The arrangement allows for trains to be added into or taken out of service with minimum disruption to ongoing operations.
Greenwood Yard is home to approximately half the Commission's fleet of trains and work cars. The yard regularly houses the majority of the fleet of T1 subway cars and all Line 2 trains overnight.
Greenwood Yard provides storage, inspection and running maintenance for the Line 2 revenue fleet, and contains major overhaul and repair shops for the entire subway fleet. Greenwood Yard is also a centre for the servicing and operation of workcars used by the Track and Structure Department to repair and maintain the entire subway system.
The Greenwood Yard also performs the heavy maintenance on the ICTS cars from Line 3 Scarborough, that the McCowan Yard cannot handle. Because the gauge and technology differences between lines 2 and 3, ICTS cars must be transported by truck to Greenwood for major maintenance work.
Greenwood Yard, like other active TTC yards, operates 24 hours per day, 7 days per week. Yard activity is minimal during the peak service periods when many trains are in revenue service. The 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.
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.
When it opened, the yard had a railway siding and some dual-gauge 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.

On the BD line, extra storage space for the T1 fleet will be provided by reopening Keele [Vincent] Yard, adding a storage track at Kipling, converting a dual-gauge delivery track at Greenwood to a storage track, and consolidating the Track & Structures fleet of work cars at Davisville.
