A few more O-Train changes in August for extension, wheel work

Partial closures and schedule changes continue this month for Ottawa's rail transit system.

3 more partial Line 1 closures, 1 more week of less Line 2 service

Partial closures and schedule changes continue this month for Ottawa's rail transit system.

OC Transpo said Tuesday that Line 1 service will be scaled back Saturday Aug. 16, Sunday Aug. 17 and Sunday Aug. 31 for more work on the extension east from Blair to Trim stations and on the St-Laurent station tunnel.

On Aug. 16 and 17, trains won't run east of Tremblay station. R1 buses will connect Hurdman station and Blair, with the usual shuttle between St-Laurent and Cyrville stations.

R1 buses will run instead of the east-west rail line the morning of Aug. 31. Trains should come back at noon.

This eastern connection work includes cameras, security systems and software and allows more driver training through the 12.5 kilometres of new track and five stations, according to OC Transpo. There should be more changes in September.

The transit service's website says the east extension should open this year. The target for its western extension to Moodie Drive and Algonquin College is 2027.

Fewer Line 2 trains some nights

The north-south Line 2 will run every 24 minutes instead of every 12 minutes after 8 p.m. from Aug. 11 to 15.

This will let OC Transpo install equipment to monitor the axle bearings on the trains, a Transport Canada requirement for Line 2.

Problems with bearings — part of what hold the wheels to the train — have previously plagued Line 1.

Line 4 to and from the airport won't be affected.
