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.

R1 Express O-Train replacement service now includes an Express option. R1 Express buses may be deployed to replace busy parts of Line 1 if the train is not running. R1 Express skips some stations to quickly re-connect you with Line 1 trains. Skipped stations are served by Regular R1 replacement service.

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.
