The city is blaming the recent O-Train derailment on human error and a spring switch that didn’t close properly.
On Aug. 11, just after 3 p.m., the O-Train travelling north toward Bayview station experienced a partial derailment as it approached Carleton station.
When the train was evacuated after the derailment, a woman in her 50s requested assistance because she was suffering from a sore neck and back. She was taken to hospital as a precaution.
No other injuries were reported.
The O-Train returned to regular service at approximately 8:45 a.m. the next day, once the necessary repairs and inspections were conducted to the track and signal infrastructure to ensure that train service could safely return to regular operation.
In a memo released Friday, OC Transpo general manager John Manconi said that a spring switch, which is a piece of rail infrastructure that moves to direct a train from one track to another, remained slightly open, causing the train’s second and third wheel sets to derail.
The train was travelling at approximately 20 km/h at the time.
“The investigation indicates that the spring switch did not properly close when a previous southbound trip travelled over it, resulting in a piece of the spring switch to become dislodged, resulting in the switch remaining in an open position,” Manconi said in the memo.
There was also a human factor at play. The operator failed to exit the train and physically inspect the track switch to ensure full alignment of the track after noting a signal light irregularity.
The operator contacted the rail traffic control centre and confirmed that the signal irregularity was not due to another vehicle being in the section of the track. The operator reduced the travelling speed in accordance with the rules.
When signal irregularities arise, operators are trained to follow Canadian Rail Operating Rules, which include exiting the train to conduct an inspection.
“This procedure was not followed in relation to this occurrence. Transit Services Department has taken the appropriate internal action to ensure adherence to operating procedures,” Manconi said in the memo.
The investigation continues. The city is also working with the train manufacturer Bombardier on the assessment of the train and to identify any necessary maintenance and repairs to the train.
