On Tuesday morning, October 27, 2026, commuter rail services on the Vaudreuil‑Hudson and Candiac lines were delayed by as much as one hour. The slowdown happened even though the lines normally share tracks with Canadian National and Canadian Pacific Kansas City, which were not responsible this time.
Montreal’s commuter rail frequently encounters delays, often tied to the use of freight railway tracks owned by Canadian National and CPKC. This incident adds to that pattern, but the usual freight‑track sharing factor was not the cause.
