The Mount Royal Tunnel (French: tunnel sous le mont Royal, tunnel du mont Royal) is a railway tunnel in Montreal, Quebec, Canada. The tunnel is the third longest in Canada, after the Mount Macdonald Tunnel and the Connaught Tunnel, and connects the city's Central Station, in Downtown Montreal, with the north side of Montreal Island and Laval and passes through Mount Royal.
The tunnel was originally proposed by the Canadian Northern Railway (CNoR) to provide access to Downtown Montreal without having to cross the already-congested area south of Mount Royal or the route around it to the east. The cost of the tunnel, along with an expansion to the west coast of Canada, caused CNoR to struggle financially before it was nationalized in 1918. Canadian National Railways (CNR), formed from CNoR and several other lines, took over the just-completed tunnel. When CNR also took over the Grand Trunk Railway (GTR) in 1923, access to Ottawa and Toronto along the GTR lines made the tunnel largely redundant, and it was limited mostly to branch lines. The structure gauge of the Mount Royal Tunnel limits the height of bilevel cars to 14 feet 6 inches (4.42 m).[2]
Until 2014, the only trains using the tunnel were commuter trains from Exo's Deux-Montagnes service. From December 2014 to May 2020, it was also used by the Mascouche line, which serves the northeastern part of Montreal Island and the suburbs of Repentigny, Terrebonne, and Mascouche. Exo also considered rerouting its Saint-Jérôme line to Central Station via the tunnel from its current termini at Parc or Lucien L'Allier to save 15 minutes.
On May 11, 2020, the Mount Royal Tunnel closed for a period of about four years.[3] It is expected to reopen in 2024, exclusively for Réseau express métropolitain services; two new stations will be added mid-tunnel as part of the works.
