R1 replacement bus service

When the O-Train is not running during regular Line 1 hours, R1 bus service may operate. R1 buses serve all Line 1 stations and only make limited stops along the way. If Line 1 is partially closed, R1 service may run only along the closed portion.

What happens during Line 1 delays or unplanned disruptions?

If rail service is disrupted, technicians will quickly respond. Our aim is to restore train service as quickly as possible. This is less disruptive to customers. If the issue is resolved within 15 minutes, train service will resume with only minor delays. Sometimes, trains can continue to run along a single track. If full train service is not quickly restored, R1 replacement bus service may be deployed. 

The decision to run R1 service depends on various factors including:

  • Time of day
  • Frequency of the train service
  • Nature of the issue causing the disruption
  • Whether some trains can continue to run along a single track. In this case, R1 service is not usually required.

If R1 service is deployed, we will help you figure out where to go.

  • Check our home page. Look for the yellow box at the top of the page.
  • Look for the info screens at the stations
  • Listen for audio announcements
  • Staff in red vests may be on-site to help you as well

We will notify you in advance of any planned rail maintenance. R1 schedules will be entered in the Travel Planner.
