Trillium Line reliability tops 99 per cent on Day 2 of testing

Article content

The Trillium Line LRT rolled through its second day of trial running Tuesday, achieving a 99.4-per-cent reliability rating.

That topped the Day 1 rating of 98.3 per cent, which was a hair-breadth away from the 98.5 per cent the trains must meet in a rolling average over the 14-day trial run. Tuesday’s results brought the rolling average over the first two days of testing to 98.9 per cent, meaning the trial run remained on track to wrap up on Oct. 21.

“We remain on a very positive trend,” Richard Holder, director of rail construction for the City of Ottawa, said during a media briefing Wednesday afternoon. “It is still early days, but I’m pleased with the results I’m seeing.”

On Tuesday, one train had a minor issue with a CCTV camera that operators would use to monitor passengers, and another had a minor delay at a terminus station when the operator switched from the controls at one end of the train to the other, Holder said.

Nine diesel trains run on the two tracks of the Trillium Line, with Line 2 between Bayview and Limebank stations and Line 4 the spur from South Keys to the Ottawa airport. A total of 65 operators are needed to keep the trains running on their seven-days-a-week service.

When the 14-day trial run is complete, the system will enter a second, seven-day period of testing when operators will practise various scenarios including two mock emergency situations — one at the airport and one in the Dow’s Lake tunnel — and a day of full-dress rehearsal with volunteer city employees playing the role of commuters on trains and in stations.

That week of testing could end as soon as Oct. 29, meaning the Trillium Line could be carrying passengers for real by mid-November.
