Here's what we know about the O-Train shutdown and R1 bus service this weekend

The O-Train remains out of service this weekend as LRT vehicle inspections and the root cause investigation continues after an axle bearing problem was discovered on one train earlier this week.

The O-Train remains out of service this weekend as LRT vehicle inspections and the root cause investigation continues after an axle bearing problem was discovered on one train earlier this week.

R1 replacement bus service is running between Blair and Tunney's Pasture stations while the O-Train is out of service. Westbound R1 service is operating from Blair to Tunney's Pasture, stopping at each station except for Lees.

As passengers wait for a bus instead of a train, the investigation continues into the axle bearing issue with no word on when LRT service will resume.

Transit Services General Manager Renee Amilcar has said LRT service will not resume until all LRT vehicle axles are inspected, adding more information will be available for transit riders and the public on Monday.

"RTG is discussing return to service scenarios with the City," Amilcar said in a memo to council on Friday afternoon.

"Key data analysis is being conducted to provide additional information for the return to service plan, with a view to providing a more comprehensive update on Monday, which will also outline next steps."

As of Friday afternoon, axle hub assemblies on 24 of 45 LRT vehicles had been checked, and no further issues were found.
