Train service has resumed on UP Express between Union Station and Pearson International Airport, but riders could encounter delays due to track repairs.
“UP Express is operating every 15 minutes today. However, due to unplanned track work, you may experience longer-than-usual wait times between trains. UP Express trains will depart Pearson Airport a few minutes earlier than the posted schedule,” a notice on the website states.
On Thursday, Metrolinx said GO Transit shuttle buses were running between Union and Pearson.
“Overnight testing identified track issues that required repair between Weston Station and Pearson Terminal,” a spokesperson for the provincial transit agency told CityNews.
Riders were notified of the service impact around 6:30 a.m. on Thursday. It is not yet known how long the repairs will take.
“Repair work is confined to the Pearson Subdivision with no impact to Kitchener corridor GO service.”
UP train service continued to operate between Union Station, Bloor, Mt. Dennis and Weston stations, Metrolinx said.
During the service disruption, commuters taking shuttle buses were picked up and dropped off at a temporary stop on Station Street, at York Street, in downtown Toronto. Metrolinx also said UP riders could also take the TTC from Bloor, Mt. Dennis and Weston stations to get to the airport, including route 900 Airport Express from Kipling Station.
