Final “readiness activities” are underway for the O-Train East extension, which will cause some delays on the line.
Customers and residents can expect to see an increasing number of out-of-service trains operating between Blair and Trim stations each week. Running these trains is part of exercising the system, identifying challenges and addressing issues ahead of time, in order to build system reliability for customers.
In a release, OC Transpo said they are working to keep service running on O-Train Line 1 and to achieve this, a condition monitoring system is being installed. This system will allow for more trains to run during daily service.
The installation of the condition monitoring system began in June and is 80 per cent ready for trial run. OC Transpo said they is on target to have enough vehicles by the end of August.
They are also working in conjunction with Rideau Transit Group (RTG) and East-West Connectors, the East Extension constructor, to determine a schedule to begin pre-Trial and Trial Running.
This work is key to building confidence that the system is operating as intended and is ready to move to Pre-Trial Running and Trial Running. As this work progresses, more updates will be available toward a schedule for trial running.
Customers can also expect to find Blair platform closed at certain times. Customers will be notified in advance when these closures are necessary.
Shortly before the start of Trial Running, trains will begin operating between Tunney’s Pasture and Trim stations.
Customers can expect the following changes:
- Although trains will continue to Trim Station, customers must disembark at Blair Station
- Passenger information display screens at stations and on trains will show Trim Station as their final destination
- OC Transpo staff will be at Blair Station to support customers through this change
OC Transpo said that before the start of Trial Running, a technical briefing will be held to provide more detailed information on Trial Running and the requirements to move towards the opening of the East Extension for customers.
