O-Train Line 1 platforms have reopened as of June 26, 2026, but trains are operating at reduced speeds following the discovery of damage to overhead wires east of the University of Ottawa. The issue was identified during routine inspections early Thursday morning, leading to a suspension of service on the affected section while crews assessed and repaired the damage.
Service Disruption and Repairs
The damage was found on the power line east of the uOttawa station, prompting an immediate halt to train movements in that area. OC Transpo officials stated that maintenance teams worked quickly to secure the affected section and implement temporary repairs. Service resumed shortly after 8:00 AM EDT, but trains are running slowly as a precautionary measure to ensure safety.
According to OC Transpo, the slow operation will continue until a full inspection and permanent repair can be completed. Commuters experienced delays of up to 20 minutes during the morning rush hour. The cause of the damage is under investigation, with early indications pointing to wear and tear from recent weather conditions.
Impact on Commuters
Riders were advised to allow extra travel time and consider alternative routes. Shuttle buses were deployed to supplement service, though they faced congestion on city streets. OC Transpo apologized for the inconvenience and assured passengers that safety remains the top priority. The slow zone is expected to remain in effect for the remainder of the day, with updates to be provided as repairs progress.
This incident comes as the O-Train system continues to face reliability challenges. In recent months, Line 1 has experienced several service interruptions due to signal issues and track maintenance. OC Transpo has committed to investing in infrastructure upgrades to improve long-term performance.
Background on O-Train Line 1
Line 1, which opened in 2019, is Ottawa's light rail transit line, connecting Blair Station in the east to Tunney's Pasture in the west. It carries tens of thousands of passengers daily. The system has faced scrutiny over repeated breakdowns and maintenance issues, prompting calls for increased oversight and funding from the city.
