Deux-Montagnes Line (AMT) - History

History

See Mount Royal Tunnel for additional information.

The Deux-Montagnes line was built by the Canadian Northern Railway. While other railways including Canadian Pacific and Grand Trunk Railway already had prime downtown locations for their terminal stations, Canadian Northern did not, having only a station out of the way on Moreau Street in Hochelaga.

In 1910, it was decided that the best way for Canadian Northern to get downtown was to drill their way downtown — through Mont Royal. The construction started at both ends and met half way through with only an inch difference. In 1918 the electrified (2400 V DC catenary), double-track 3.2 mi (5.15 km) tunnel was dubbed Montreal’s first subway. Because the tunnel is inadequately ventilated it was decided from the very beginning that the locomotives would be electric. The ventilation shaft is located SW of the intersection of Édouard-Montpetit Boulevard and Vincent-d'Indy Avenue very close to the Édouard-Montpetit Metro Station.

The structure gauge of the Mount Royal Tunnel limits the height of bilevel cars to 14 ft 6 in or 4.42 m.

In order to finance the project, Canadian Northern built a ‘model city’ north of the tunnel, modeled after Washington, D.C. The Town of Mount-Royal has grown to be an upper-income neighborhood today. Construction began in 1912 and finished in 1918. The first train was pulled by electric locomotive #601 (retired as #6711), which left Tunnel Terminal at 8:30 a.m. on October 21, 1918. The Canadian Northern Railway went bankrupt and was absorbed into what is now Canadian National. Tunnel Terminal was replaced by Central Station in 1943.

In the 1960s, the first plans were announced to renovate the line, whose equipment was 40 years old at the time. First, it was to become metro line 3, but plans were shelved because of the importance to build line 4 for service to Expo 67. With the equipment ageing, and ridership declining, CN wanted to close the line in the 1970s, but their proposals were rejected. The Quebec Ministry of Transport considered using the line for a high-speed connection to Mirabel Airport (Transport rapide régional aéroportuaire Montréal Mirabel, 1974) or as the first line of a BART-style regional metro system (Réseau express de Montréal, 1977; Métro régional, 1979). None of these projects progressed beyond the planning stage.

In 1982, the fares for the trains were integrated with the fares for the Metro and buses. The fare was two bus tickets. This was later reduced to one from Central Station to Val-Royal (now Bois-Franc).

In 1992, the government of Quebec announced a modernisation plan for the line which would include 58 state-of-the-art 25 kV AC MR-90 electric multiple-unit trains built by Bombardier Transportation, new tracks, and centralised traffic control. Service was shut down completely in the summers of 1993, 1994 and 1995 to allow for major work to be done. The last of the old rolling stock left Central Station at 6:30 p.m. on June 2, 1995 – 76 years, 8 months, 11 days, and ten hours after it first went into service. The same locomotive, #6711 (with #6710 (pictured)), hauled the last train through the tunnel.
