- UPDATE: On Oct. 18, 2024, OC Transpo revised its closures. The changes are now reflected in the story.
Ottawa transit riders travelling from Blair to Tremblay station may need to use replacement buses on weekends and some late nights as OC Transpo works a series of scheduled repairs and upgrades to the rail line.
An OC Transpo memo announced that maintenance will impact service between Saturday, Oct. 19 and Sunday, Nov. 3.
The R1 replacement bus service will operate during closures.
Here are the affected times:
- Oct. 19 and 20: Line 1 will be partially closed for the weekend. The train will run from Tunney’s Pasture to Tremblay station and R1 buses will service Hurdman to Blair stations.
- Oct. 22 and 23 and Oct. 29 and 30: After 11 p.m., Line 1 will be partially closed, only running from Tunney’s Pasture station to uOttawa station. The R1 will service Rideau station to Blair station.
- Oct. 26 and 27 and Nov. 2 and 3: Full closure of Line 1. R1 will run from Tunney’s Pasture station to Blair station.
During the closures, Rideau Transit Maintenance will be conducting ballast stabilization work between Hurdman and Tremblay stations and rail-grinding across the entire line.
Rail-grinding removes corrugation and leads to smoother transitions when entering and exiting turns, according to an October OC Transpo update.
Additional outstanding work will be done during the closures, such as the Ontario Structure Inspection Manual inspection of the St-Laurent tunnel.
