GO Transit is operating on a modified service on Tuesday after a train derailed Monday morning, taking multiple transit lines out of service and causing commuter chaos.
Metrolinx CEO Michael Lindsay made the announcement on LinkedIn, which was later implemented by GO Transit.
“We have confirmed that we will be running a modified service [Tuesday] which solves for the maximum number of train trips on our busiest lines at peak periods,” Lindsay added, stating that riders should look at the GO Transit website for further details.
The derailed train was removed from the tracks early on Tuesday morning, CityNews confirmed.
“Please visit ‘See Schedules’ to view modified trip times and to plan ahead. While we work to provide you with consistent service, we recommend allowing yourself extra time to get to where you are going,” reads an alert posted to the GO Transit website.

The train, which was departing Union Station, encountered an issue that caused the rear of the train to come off the track and make contact with a track switch around 8:16 a.m on Monday, according to Metrolinx. No injuries were reported in the incident.
GO riders stranded and frustrated after derailment
Metrolinx said passengers were on board the Kitchener-bound train, but they were safely transferred to another train shortly after the incident. The rest of the day was filled with delays, cancellations and frustrated commuters.
The derailment also led to a temporary suspension of UP Express service between Union Station and Toronto Pearson International Airport earlier in the day.
