Line 1 Yonge–University has part(s) North York Centre
Line 1 Yonge–University is a rapid transit line on the Toronto subway. It serves Toronto and the neighbouring city of Vaughan in Ontario, Canada. It is operated by the Toronto Transit Commission, has 38 stations and is 38.4 km (23.9 mi) in length, making it the longest line on the subway system. It opened as the "Yonge subway" in 1954 as Canada's first underground passenger rail line, and was extended multiple times between 1963 and 2017. Averaging over 850,000 riders per weekday, Line 1 is the busiest rapid transit line in Canada, and one of the busiest lines in North America.Operations and extensions from 1954 to 2017
Trains operated at average speeds of 32 kilometres per hour (20 mph). The plan to operate two-car trains during off-peak hours was abandoned in favour of four-car trains, and six-car trains were standard during most periods, with some eight-car trains used during peak periods.On February 28, 1963, an extension was added to curve north from Union Station, below University Avenue and Queen's Park to near Bloor Street, where it turned west to terminate at St. George and Bloor Street.On February 26, 1966, the Bloor–Danforth line opened, from Keele to Woodbine. For six months, as a trial, the Yonge–University line operated as 2 branches, Eglinton-Keele, and Eglinton-Woodbine. The interline was determined not worthy, and the Yonge-University line was cut back to St. George on September 4, 1966.On June 23, 1969, the University subway service from St. George to Union stations was discontinued entirely after 9:45 p.m. from Mondays to Saturdays and all day on Sundays and holidays. The 5B Avenue Road buses runs in place between Eglinton and Front Street whenever the University subway did not operate, with side-jaunts to St. George station to capture passengers from the Bloor subway. This arrangement remained in place until January 28, 1978, when the Spadina subway opened north to Wilson Station.On March 31, 1973, the line was extended north from Eglinton to York Mills, and on March 29, 1974, to Finch. These two extensions were part of the North Yonge Extension project, bringing the subway to North York.Stations were also planned for Glencairn (between Eglinton and Lawrence, though another Glencairn station would be built later on the Spadina section), Glen Echo (between Lawrence and York Mills) and Empress (between Sheppard and Finch, later opened as North York Centre station).On January 27, 1978, the Spadina segment of the line was opened, going from St. George station, the north terminus of the University line, to Wilson station. From St. George station, the 9.9 km (6.2 mi) segment ran north and northwest to Eglinton Avenue and William R. Allen Road, then north along the median of the Allen Road to Wilson Avenue. This extension had been proposed as part of the Spadina Expressway, but when the expressway portion south of Eglinton Avenue was cancelled after massive protests, the subway was still built following the route through Cedarvale Ravine. Hence, it was called the Spadina line, though it follows Spadina Road for less than 2 km (1.2 mi).
