Calgary, Alberta Trolley Coach Overhead Map, as of April, 1974

Source: H.R. Porter, editor, Trolley Coach News, Vol. 7, Number 3, Summer 1975,  Map drawn by Wayne Hom on April 1974 and revised on 5/23/74.

Calgary had an interesting trolleybus operation that was established after World War II and was abandoned in 1975.  Calgary today has a modern light rail system.  The trolleybus system started on June 1, 1947.  Some coaches and other equipment may have gone to Edmonton and Vancouver after closure. I hope the maps are useful to the historians out there.
