Toronto subway
In October 1976, an arson (a fire set on purpose) destroyed subway cars and damage to Christie station. This caused the closure of the Bloor-Danforth Line for three days, and closed Christie station for some time for repairs. More track was added in 1980 at both ends of the Bloor-Danforth Line. These extensions each added one station, bus bays, and, on the eastern end, room to connect to the Scarborough RT.
