O-Train Line 1 Service Disrupted by Overhead Wire Issue

Commuters in Ottawa faced significant delays on Thursday, November 20, 2025, as service on the Confederation Line, known as O-Train Line 1, was reduced to a single track. The disruption was caused by a discovered defect in the system's overhead power wires.

Cause and Immediate Response

According to OC Transpo, the problem was identified at approximately 8 a.m. on a section of the overhead catenary system located between Rideau and uOttawa stations. In a memo to city council, Troy Charter, the interim general manager of transit services, explained that a specific component of the wire system was faulty. He stated that this element required replacement before trains could safely travel through the affected area to prevent further damage.

Maintenance crews were scheduled to perform the necessary repairs overnight, once LRT operations had concluded for the day. Charter anticipated that full service on Line 1 would resume by Friday morning.

Impact on Commuters and Service Adjustments

While Line 1 continued to operate along its entire route from Tunney’s Pasture to Blair stations, the single-track operation necessitated significant service adjustments. Passengers were advised to expect longer travel times throughout the day.

Specifically, one track between Rideau and uOttawa stations was taken out of service. As a result, Line 1 service was only available on the westbound platform at both Rideau and Parliament stations. This configuration was implemented to manage the flow of trains through the constrained section while repairs were being organized.

The incident is the latest in a series of challenges for Ottawa's light rail system, highlighting the ongoing attention required for the city's public transit infrastructure.
