The Toronto Zoo Domain Ride was an automated guideway transit service used to carry visitors between sections, or "domains", of the Toronto Zoo. Though technologically closer to a simple rubber-tired metro, it was almost universally referred to as a "monorail".
The train began running in 1976, and closed in 1994, after a train lost power and rolled backwards down the track into a second train, injuring about 30 people. Parts of the line were subsequently taken over by the Zoomobile, an open-air tractor-drawn vehicle with five stations which had been operating since 1980.
