O-Train Line 1 will partially close early Friday and Saturday night, as the annual spring and summer maintenance program begins on Ottawa’s nearly six-year-old light-rail transit line.

The LRT line that runs between Tunney’s Pasture and Blair stations will shut down several times through the spring and summer for annual maintenance and work required for the O-Train East Extension integration ahead of the launch of service between Blair and Trim Road later this year.

In a memo to council, Transit Services general manager Renée Amilcar announced the plan for upcoming service adjustments on the Confederation Line in June and July.

“All rail systems require regular maintenance to support the long-term sustainability and reliability of the system,” Amilcar said. “This year, in addition to working with Rideau Transit Maintenance (RTM), OC Transpo has coordinated with the Stage 2 project and Infrastructure and Water Services Department (IWSD) in order to address multiple priorities in parallel to minimize the number of disruptions to rail service for customers.”

Maintenance activities in June include:

• Line 1 train control server upgrades
• Localized rail replacement at “specific locations”
• Ongoing upgrades of supporting wires on the overhead catenary system “to make them more resilient and durable.”
• Adjustments to track electrical grounding near Tunney’s Pasture Station
• General station maintenance and seasonal cleaning
• Testing and integration of the Stage 2 O-Train East Extension with Line 1

Here is the planned service adjustments for O-Train Line 1

• June 6: No LRT service between Tunney’s Pasture and uOttawa Station after 9 p.m. R1 bus service will run between Tunney’s Pasture and Hurdman stations.
• June 7: No LRT service between uOttawa Station and Blair Station after 10 p.m. R1 bus service will run between Rideau and Blair stations. R1 bus service will run between Rideau and Blair stations.
• June 8: No LRT service between uOttawa and Blair stations after 7 p.m. R1 bus service will run between Rideau and Blair stations.
• June 12: No LRT service between uOttawa and Blair stations after 10 p.m.R1 bus service will run between Rideau and Blair stations.
• June 14-15: No LRT service all weekend. R1 bus service running along the O-Train Line
• June 22 and June 29: No LRT service between 8 a.m. and 12 p.m. R1 bus service running along the O-Train Line

Amilcar says additional Stage 2 integration work will occur on the weekends of July 5 and July 26 that will affect Line 1 service.

“Every effort has been made to conduct Stage 2 integration work at the same time as other maintenance activities; however, additional service adjustments are required to complete testing activities,” Amilcar said.

“It is also anticipated that there will be additional impacts to Line 1 throughout the summer as the O-Train East Extension testing and commissioning progresses and, in the fall, to conduct rail grinding.”
