City, LRT builders apologize for latest breakdown

Officials are apologizing after a power line atop one of Ottawa's new LRT trains snapped as it entered St-Laurent station Thursday, halting service between Hurdman and Blair stations and throwing the afternoon commute into turmoil for thousands of riders.

The broken line was repairedovernight, so Confederation Line service was restored by Friday morning.

The inspections and testing necessary to get full service back on the Confederation Line were finished at about 4:15 a.m., saidRideau Transit Group (RTG) chief executive officer Peter Lauch at a news conference later Friday morning.

Lauch said it appears the power cable snagged on something as the eastbound train entered the station around 10:50 a.m., but said the exact cause of the incident is still under investigation. On Thursday, he said RTGhadn't experienced a similar problem during testing last fall.

OC Transpo'soperations director Troy Charter explained it's at St-Laurent where the wire, which hangs free atopen-air stations, becomesfixed to the ceiling.

A timeline

Lauch explained there's a tension sensor on the system's power lines that detect when something goes wrong and immediately "de-energizes" the system, which is what happened Thursday.

"It's like a fuse in your house," he said, adding that passengers' safety was never at risk.

Crews made sure the power stayed off as they cut and removed the wire from the train, Lauch said, before moving the train to a storage facilitywhere it's undergoing repairs.

About 35 metres of overhead guiderail for the power line was damaged and some supporting parts were bent or broken in the incident, he said.

Lauch saidworkers repaired the guiderail, restored power and conducted tests, all in time to resume normal service Friday morning.

Pat Scrimgeour, OC Transpo's director of customer systems and planning, said there were four different contingency plans in case the system wasn't ready for5 a.m., but they weren't needed.

Serious disruption

East-end commutershad to rely on backup bus service through the afternoon rush hour.

The nearly 15-hour disruptionwas by far the longest since the Confederation Line's launch in September.

Scrimgeoursaid this was the first time they had to call in all 60 to 70 replacement R1buses OC Transpo has available.

"This really sucks, actually waiting in this cold weather with this amount of people waiting for a bus just to get home," OC Transpocustomer Joe Green, bundled in a toque and hoodie, said Thursday.

"Me as a construction worker, I don't have [an option to work]at home,"said Rory Brissett. "The train is my only access [to work] other than driving."
