Exo commuter rail
Exo commuter rail (reporting mark EXO) is a system of five radial commuter rail services serving the Greater Montreal area. The network is operated by Alstom using trackage owned by Exo, the Canadian National Railway (CN), and Canadian Pacific Kansas City (CPKC).
Exo's commuter trains are its highest-profile division. It uses diesel-electric push-pull trains. The Mont-Saint-Hilaire and Mascouche lines run on CN trackage, while the Vaudreuil–Hudson, Saint-Jérôme, and Candiac lines run on CPKC trackage and operate out of Lucien L'Allier terminus. The Saint-Jérôme line also runs on Exo's own trackage between Sainte-Thérèse and Saint-Jérôme, as does the Mascouche line between Repentigny and Mascouche and the Vaudreuil–Hudson line between Vaudreuil and Hudson.
Operation of all commuter rail was provided by contract to CN and CP (on their respective rail networks) until June 30, 2017. Operations were taken over by Alstom (then Bombardier Transportation) beginning July 1, 2017, on an 8-year contract.
The train lines are part of Greater Montreal's integrated public transit network including bus, regional rail (REM) and Metro, coordinated by the Autorité régionale de transport métropolitain (ARTM). Many train stations serve local bus terminals, and a few provide connections to Metro, REM and Via Rail and Amtrak national rail services.
