Planned Construction
Planned Construction
More trips, more connections, more of what you need.
To keep these plans on track, we sometimes work overnight and on weekends, building and updating rail infrastructure, renovating stations, building new train platforms, and more.
We aim to provide you with plenty of notice when we need to adjust service for construction activity. Please plan your trip in advance.

What type of work is happening:
Metrolinx is transforming GO Transit to bring more frequent two-way, all-day service to the Kitchener line seven days a week. This planned track work requires us to temporarily suspend service on UP Express so that construction can be performed safely.
