The Expo Express was a rapid transit system consisting of five stations and a route, running from Cité du Havre to La Ronde in Montreal, Quebec, Canada. Built for the 1967 World's Fair (Expo 67) at a cost of around CAD$18 million, the trains carried 1,000 passengers each and ran approximately every five minutes. In 1968 the cars were sold to the City of Montreal for $1.8 million and operated by the Montreal Transit Commission (now the STM). The train remained in limited service for Man and His World for five additional years, however, on a shortened route from 1969-onwards when tracks were cut back to Saint Helen's Island. Service was withdrawn in 1972. Vehicles Not to be confused with the Minirail monorail which ran within the perimeters of the Expo Site, the Expo Express used standard railway technology, with two running rails and a third electrified rail identical to those of the Toronto subway. In fact, the trains used were a modified version of the Hawker Siddeley H series used by the Toronto Transit Commission with one fewer door on each side, and streamlined ends. Consequently, unlike the Montreal Metro with rubber tires, the Expo Express used traditional steel-wheeled trains. The Expo Express also featured fully air-conditioned passenger cars, also unlike Montreal's underground Metro (a deficiency that still exists to present day). The fleet of rolling stock consisted of 48 cars in total, with the name of a sponsoring Canadian city or local municipality inscribed in large lettering on both sides of each car (e.g. "Richmond, B.C.", "Town of Mount Royal", "Point Claire, Quebec", "Cornwall, Ontario"). Background The Expo Express was the first fully-automated rapid transit system in North America, utilizing an Automatic Train Operation (ATO) system based on audio frequency track circuits furnished by the Union Switch & Signal division of Westinghouse Air Brake Company. This fact, however, was not widely publicized during the fair, as it was felt the public would not readily board a train controlled entirely by a computer. Operators from Montreal's transit union were placed in cabs at the front and given mundane tasks such as opening and closing the doors of the train to reduce boredom. This resulted in a minor incident during the fair, at La Ronde station. The conductor had pressed the button to close the doors and proceed, but his train had already sensed an oncoming express from Notre Dame
