The Red Line, also known as Route 201, is a light rail transit (LRT) line in Calgary, Alberta, Canada. Partnered with the Blue Line, and future Green Line it makes up Calgary's CTrain network. Following its initial approval in 1976, the Red Line opened in 1981, running from Anderson station in the southeast into downtown. The Red Line has gone through a series of expansions, which bring it to its current design. The Red Line services the northwest quadrant and south end of the city beginning at Tuscany station, runs through the downtown core on 7th Avenue, then proceeds southbound where it terminates at Somerset–Bridlewood station. The section of track running along 7th Avenue is shared with the Blue Line. Future expansion of the Red Line includes rerouting the downtown section below 8th Avenue, which would allow the operation of five-car trains, further increasing capacity.
