Here's what you need to know about the third week of the O-Train shutdown and R1 bus service

CTVNewsOttawa.ca looks at what you need to know about the O-Train shutdown and the R1 replacement bus service heading into week three with disrupted service.

Ottawa's light-rail transit system will remain out of service for a third straight week, as Rideau Transit Group continues to work on the tracks and replacing the wheel hub assemblies and axles on all trains.

OC Transpo had hoped to resume partial service on the O-Train line on Monday with eight single-car trains running every seven to eight minutes, but RTG told the city on Friday that more work on the tracks is needed before service resumes.

Transit Services general manager Renee Amilcar says OC Transpo and RTG will spend the weekend developing a new risk assessment for the work to ensure the track infrastructure conforms to the new Safety Note.

Details on the "risk assessment" plan to fix the tracks will be released on Monday, but Amilcar has already said it will take at least 10 days to complete the track infrastructure work and resume service. That means it could be the second week of August, at the earliest, before LRT service resumes.

R1 replacement bus service continues to run between Blair and Tunney's Pasture stations while the O-Train is out of service.

"The revised R1 route is operating well, and we continue to monitor it closely," Amilcar said in a memo Saturday morning.
