OTTAWA – An Ottawa LRT car caused damage inside Tremblay Station and along the tracks that stretched back to St. Laurent Station, before finally stopping west of Riverside Drive last month.

The Danish Transport Safety Agency published new photos showing scratches from the LRT car along the north side platform and staggered rail tiles inside Tremblay Station, plus “impact marks” with sporadic gaps on rail tracks, rail clamps and clip holders along the tracks to the previous station caused by contact from an “indeterminate component” in the vehicle.

TSB is still looking for the cause of the derailment of 19. September, which has closed the Confederate line for the past two and a half weeks.

In a report released Thursday, TSB said the LRT car “derailed near the center” of the northern platform at Tremblay Station around 12:15 p.m., but no problems were observed as the train entered the station or left.

The train approached the eastern end of Tremblay Station at approximately 35 km / h and was brought to a controlled stop within the station.

“After some passengers left the train, the doors closed and the train began to accelerate slowly and then rapidly up to about 35 km / h. No unusual train handling was reported, nor were trace anomalies observed prior to the train,” said TSB .

“After crossing the railroad bridge that crosses Riverside Drive, a train-initiated emergency brake allegedly occurred and the train stopped west of the bridge.”

The LRT car hit a signal mast and switch heater adjacent to the track.

TSB investigators conducted an ongoing inspection of the track from the derailed LRT car east to St. Laurent Station.

“The ballast was disturbed along the entire north side of track 1. The derailed LRV had contacted and destroyed a signal mast and switch heater adjacent to, and north of, track 1,” said TSB. “The path next to the signal had tense as a result of the derailment and was not considered causal.”

Ballast is heavy material, e.g. Gravel, iron or lead used to form a railway track.

LRT Derailment

The LRT said ballast along the field side of the track was disturbed at about 1,400 feet, up to near the center of the northern platform within Tremblay Station.

“The disturbed ballast extended up to and next to the northern platform at Tremblay Station and ended near several staggered bands near the center of the platform,” said TSB.

“Scratches were observed along the side of the north platform at Tremblay Station. The damage was consistent with similar damage observed on the north side passenger door sill just above the engine-bogie 2 location of LRV 1121.”

LRT Derailment

Between St. At Laurent Station and Tremblay Station, impact marks with “sporadic intervals” were observed on rail tiles, rail clamps, clip holders and bolts, TSB said.

“The frequency of impact signs increased slightly approaching the eastern end of Tremblay Station,” TSB said. “The impacts observed were consistent with some form of mechanical damage likely due to contact with an indeterminate component of LRV 1121.”

The derailed wheels were cut by bolts on the rail connections along the LRT track.

The next steps in the investigation include an investigation of all components and wrecks of the train, an investigation of the LRT car and a review of information received from OC Transpo and Rideau Transit Group.

Rideau Transit Group said on September 20 that it could take three weeks to repair the damage and resume LRT service. Coun. Allan Hubley, chairman of the Transit Commission, told CTV Morning Live on Thursday morning that he did not have a resumption of service, but it would be weeks, not months.

A FEDCO proposal said the city of Ottawa found RTG’s plan to reduce service and schedule to be unsatisfactory. No information on RTG’s plan to resume service was made public.
