Canada’s Transport Watch Dog has released new photos and details of the latest derailment on Ottawa’s light rail transportation system showing the damage to Tremblay Station and the surrounding infrastructure.
The letter, sent Thursday by the Transportation Safety Board in Canada, does not suggest why the LRT train left the tracks on September 19, but shows more details about the timeline for the derailment that Sunday afternoon.
TSB said in its initial results that the train “derailed near the center of Tremblay Station’s northern platform” as it ran west around 1 p.m. 12:15

The train had stopped at Tremblay to drop off a couple of passengers before continuing towards Hurdman Station across a railway bridge.
“No unusual train handling was reported, nor were trace anomalies observed before the train,” the TSB report said.
The train accelerated to a speed of about 35 kilometers per hour in derailed condition, according to the report.
But as it reached the railroad bridge over Riverside Drive, it hit a signal mast and switch heater along the way, an emergency brake was applied to bring the train to a stop just west of the bridge.
The 12 passengers on board were then escorted off the train after about a half-hour wait.

The TSB report said it was the rear train, called LRV 1121, that derailed on September 19th.
An investigation of the site after the derailment showed damage along the side of Tremblay Station’s northern platform. Scraping shown in photos included in the report was consistent with damage to the train’s passenger door, TSB said.
The ballast – pieces of rock that form a foundation around the tracks – was disturbed for about 1,425 feet or 425 meters outside Tremblay Station.
The derailed wheels had also impacted or cut off bolts on the south side of the guard rail on the railway bridge.
TSB’s investigation is ongoing. The watchdog cleared the derailed train to return to the city’s maintenance facility after its initial inspection was completed.
Next, TSB must remove the engine bogie from LRV 1121 to get a closer examination of the derailed wheels.
No timeline has yet been given for when Confederation Line LRT will be up and running for either full or partial service. R1 replacement bus service has been running along the back track in the light rail system in the meantime.
The city rejected the Rideau Transit Group’s original plan to put the system back into operation as “unsatisfactory under all conditions” and issued another default warning against the railway construction and maintenance company five days after the derailment of 19. September.
