Express train service between downtown Toronto and Toronto Pearson Airport in Mississauga has been shut down Monday morning due to a disabled train, officials say.

Transit officials in charge of the Union Pearson Express, which transports passengers between Canada’s biggest and busiest airport and Union Station in Toronto, said “due to a disabled train west of Union Station, there is currently no UP Express train service to or from Pearson Airport.”

Officials added that express bus service is running between Union Station and Pearson, but customers at Weston, Mount Dennis and Bloor stations on the UP Express line are advised to take the TTC as an alternative.

When operating, UP Express trains take passengers between Union Station and Pearson in 25 minutes or so. Express trains run every 15 minutes daily until 1 a.m. between downtown Toronto and Pearson.

Officials at Metrolinx, the provincial agency that oversees the UP Express and GO Transit, said earlier the express train service “has become an integral part of transit in Toronto, having served more than 26 million passengers” since its inception in 2015.

In what at the time was the “first dedicated express air-rail link service in North America,” the UP Express took its first passengers between Pearson and Union Station in downtown Toronto on June 6, 2015, Ontario transit officials said earlier.
