as a prototype site, the new Toronto Zoo that would be opening in 1974. The zoo covered , which made walking the site a difficult proposition. Boeing also entered a bid based on their new version of the Alden staRRcar. At the same time, the provincial government was in the midst of planning a major AGT system known as GO-Urban, and Bendix was one of many companies to bid for that project. The Zoo system would be an excellent demonstration for the GO-Urban decision. For the zoo deployment, a greatly simplified operating system was needed. Since the schedules were relatively slow, on the order of 10 minutes between trains, the automated system was not needed. The cars were modified to place a small operator cabin at the front of some of them, entered through a separate door. Trains normally operated in four-car units, with the cabins facing front and rear. The rear-facing cabin was used while backing up the trains. The operator also doubled as the tour guide. Three miles of track wound around the site, with a spur running to a maintenance depot at the northern end of the zoo. Most of the track was laid at ground level, although there were elevated portions above terrain features. In spite of operating on four wheels similar to a bus, the system was often referred to as a monorail. Twenty-four vehicles were purchased for the system, sometimes operating in four-car trains during periods of increased demand. Known as the Toronto Zoo Domain Ride, the system opened in 1976. In March 1991 nine people were injured when two trains collided. In spite of a warning that major maintenance was needed to fix problems in the brakes and motors, in 1994 another accident occurred that injured thirty. The zoo was fined $43,000, and instead of fixing the system the board of directors decided to close the system, and operations ended that year.
