OC Transpo LRT Trillium Line tests perfect again

Article content

For the third time since the start of testing last Monday, the Trillium Line  LRT scored a perfect 100 per cent reliability rating on Saturday, boosting the rolling average to 99.5 per cent.

TransitNEXT, the consortium that built the Trillium Line, must meet a 98.5 per cent reliability rating over the full 14-day trial run.

Trial running is still on track to finish up on Oct. 21.

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.

According to the scoring system, “on-time” performance means trains must depart within 30 seconds of schedule from each terminus station: Bayview and Limebank for Line 2; and South Keys and the airport for Line 4.

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.

The Trillium Line uses two types of trains: the Stadler FLIRT and Alstom LINT. Unlike the electric-powered Confederation Line, Trillium Line trains run on diesel. Trains run every 12 minutes and can hold up to 600 passengers, with 300 in each of their two cars.

Here’s what’s happened so far during testing:

Friday, Oct. 11

The Trillium Line scored a 99.4 per cent reliability rating on its fifth day of testing Friday, keeping the rolling average to 99.4 per cent.

Thursday, Oct. 10

For the second day running, the Trillium Line LRT scored a 100 per cent reliability rating on its fourth day of testing. Thursday’s 14-day rolling average was 99.4 per cent.

Wednesday, Oct. 9

The Trillium Line LRT scored a perfect 100-per-cent reliability rating on its third day of testing. Wednesday brought the 14-day rolling average to 99.3 per cent.

Tuesday, Oct. 8

“We remain on a very positive trend,” Richard Holder, director of rail construction for the City of Ottawa, said during a media briefing Wednesday. “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.

Monday, Oct. 7 — Trillium Line testing starts

The Trillium Line LRT achieved a 98.3-per-cent on-time performance during its first full day to trial running on Monday.

That was just shy of the 98.5 per cent score that builder TransitNEXT must achieve as a rolling average over the full 14-day trial running period, but City of Ottawa Transit General Manager Renée Amilcar said she’d take it.

“I’m very, very happy — 98.3 per cent is very good, especially for the first day,” Amilcar said Tuesday in the first daily briefing to reporters during the testing phase.

A minor brake problem delayed the deployment of one of the Trillium Line’s nine trains in the morning, while two other trains experienced problems with the CCTV cameras showing the operator the platforms and doors, said Richard Holder, director of rail construction for the city.
