O-Train Line 1 Service Disruption - December 13, 2025

Sent on behalf of Troy Charter, Interim General Manager, Transit Services

Mayor and Members of Council, 

The purpose of this email is to advise that, at approximately 4:50 pm on Saturday, December 13, a defect was discovered with support elements for the Overhead Catenary System (OCS) on O-Train Line 1 near uOttawa Station.  Line 1 continued to run and service to all stations during this time. Rideau Transit Maintenance (RTM) commenced repairs to the defective piece as soon as Line 1 service ended but were unable to complete their work before start of service this morning. As a result, Line 1 service launched at 8 am with the following adjustments in place:

• R1 implemented between Tunney’s Pasture and Hurdman Station

• Service on Line 1 running in a loop between Hurdman and Blair Stations  

Staff and RTM are working to restore full Line 1 service as soon as possible. Information is being shared with transit customers through social media, text alerts, web updates, and station announcements. We thank our customers for their patience during this incident.

Thank you,      

Troy Charter

Mayor and Members of Council, 

Further to my last message, full Line 1 service was restored between Tunney’s Pasture and Blair Stations at approximately 2 pm today. Partial R1 service was maintained until the transition was complete to ensure support to customers.  Further investigation and troubleshooting will occur in an effort to prevent a re-occurrence.

We thank our customers for their patience during this incident.

Thank you,      

Troy Charter
