The TSB team is in the field phase of this investigation. We’ve completed our documentation and data collection at the site, but much work needs to be done. Going forward we will focus our efforts on:
Crossing design and associated risk
- Review alignment of crossing;
- Review of roadway alignment;
- Evaluation of visibility of the crossing protection from roadway and potential obstructions;
- Assessment of regulatory requirements for automated crossing protection.
OC Transpo Bus
- Detailed mechanical examination of the bus;
- Analysis of all available recorded memory from modules within the bus.
- Factors that may have affected driver performance;
- Bus operations and driver training;
- Ergonomic assessment of the driver station.
- TSB specialists have spoken to the next of kin of the victims;
- Interviews are ongoing with survivors and witnesses, OC Transpo personnel and first responders.
This investigation will require considerable time and effort. The TSB is committed to conducting a comprehensive and thorough investigation. Our efforts will be aimed at explaining what happened and why, in the hopes that what we learn will help prevent accidents like this. If at any time during the investigation a safety deficiency is identified which requires immediate attention, we will notify the appropriate authorities and inform the public.
