S1 supplemental bus service

When the O-Train does not have enough trains to meet regular service levels, S1 bus service may operate. S1 buses add a direct peak-period service option between Tunney’s Pasture, Blair or Hurdman and downtown.

S1 service runs together with the train. This service reduces the likelihood you will need to wait for multiple trains until there is enough space to board.

If S1 service is required, you may experience longer travel and wait times. Platforms and trains may be more crowded as well. O-Train Ambassadors in red vests will be on site to help and direct you.

S1 service may be deployed for the morning or afternoon peak period. S1 buses run non-stop between Hurdman or Tunney’s Pasture and downtown.

If R1 service is needed while S1 service is running, R1 would replace S1 service. S1 service would therefore be cancelled.
