Platforms on parts of O-Train Line 1 were packed with passengers after a stopped train disrupted the afternoon commute on the light rail line that is already operating at reduced capacity due to another issue.

OC Transpo reported a stopped train at 5:41 p.m. in alerts and on social media, telling riders that service would be operating on the eastbound platforms only at Pimisi and Bayview stations. Customers were asked to change trains at Lyon Station, in the downtown tunnel.

“West platform will service eastbound trips, and east platform will service westbound trips,” OC Transpo said.

Passengers shared photos of packed platforms at Lyon during the 6 p.m. hour.

“At approximately 5:25 p.m., a Line 1 train became immobilized near Pimisi station due to a mechanical issue,” OC Transpo spokesperson Katrina Camposarcone-Stubbs said in an email to CTV News Ottawa. “Despite troubleshooting efforts, teams were unable to resolve the issue and customers were safely transferred to the station. Service continued along Line 1, with service provided only on the eastbound platforms at Bayview and Pimisi stations.”

Regular service resumed at 7 p.m., according to OC Transpo.

O-Train Line 1 is running at reduced capacity this week because of a spalling issue affecting the vehicles that was first discovered last week. Forty-one of 59 vehicles were pulled out of service for inspections and part replacements.

Currently, OC Transpo is running 15 trains on the line, when it usually uses 26 during peak periods. Some trains are also coming as single-car vehicles, adding to crowding.

There is no timeline for when the spalling issue will be resolved. Staff say they are working to make sure they have as many trains available as possible while balancing system safety.
