CTrain is a light rail transit system in Calgary, Alberta. It is operated by Calgary Transit, a public transit service owned by the City of Calgary and operated through its Transportation Department. Service began on the initial downtown transit corridor and south line in 1981. It expanded to northeast Calgary in 1985, to the University of Calgary in the city’s northwest in 1987 and to the city’s west side in 2012. Most of its route and stations are at surface level. Calgary Transit operates the CTrain in conjunction with an extensive network of bus routes. Through equivalency purchases of wind-generated electricity, it has been entirely wind-powered since 2001. Its two separate lines comprise 45 stations, 118.1 km of track, and an average daily ridership of 312,300 (2018).

Numerous tragedies have unfolded on Canadian roads and highways, the deadliest being a bus crash that killed 44 people in Quebec in 1997. Despite the death toll in such headline-grabbing disasters, Canada’s motor vehicle fatality and injury rates are steadily declining, thanks to engineering improvements in vehicles, and the increasing promotion and awareness of safe driving practices.
