context_page_description: The Toronto subway is a rapid transit system serving Toronto and the neighbouring city of Vaughan in Ontario, Canada, operated by the Toronto Transit Commission. It is a multimodal rail network consisting of three heavy-capacity rail lines operating predominantly underground, and one elevated medium-capacity rail line. Two light rail lines, which will operate both at-grade and underground, are under construction.
  In 1954, the TTC opened Canada's first underground rail line, then known as the "Yonge subway", under Yonge Street between Union Station and Eglinton Avenue with 12 stations. As of 2018, the network encompasses 75 stations and 76.9 kilometres of route. Over 216 million unlinked rides were completed on the system that year, and with 1.58 million riders every weekday, it is the busiest rapid transit system in Canada in terms of ridership.
context_section_description: The heavy-rail subway lines were built in multiple segments with multiple crossovers. These are typically used for reversals at terminal stations, and allow arriving and departing trains to cross to and from the station's farside platform. They are also used for short turning trains at some through stations in order to accommodate emergency and planned service suspensions. Planned service suspensions generally occur on weekends for planned maintenance activities that are impractical to perform overnight. There is only one regular short turn service that occurs during the morning rush hour on Line 1 Yonge–University when some northbound trains short turn at   Glencairn.
  On Line 3 Scarborough, light metro trains cannot switch directions except at the ends of the line as there are no intermediate crossovers between the two termini. Thus, there can be no short turns on Line 3.
