New TSB regulations came into effect on July 1, 2014, changing some reporting requirements.
* Under new reporting requirements all derailments are reportable. As of January 1, 2017, some derailments and collisions with minimal consequences will be categorized as reportable incidents, including:
Derailments involving 1 to 2 cars, with no equipment or track damage, no injuries, no fires, and no release of dangerous goods.
Non-main-track collisions, with no equipment or track damage, no injuries, no fires, no release of dangerous goods, and did not foul the main track.
For previously reported occurrences (going back to January 1, 2014), the TSB will review these types of occurrences and make adjustments to the category (as required). As such, until the review is completed, monthly statistics involving these types of occurrences will continue to change as the records are updated. In addition, on an ongoing basis, some occurrences, initially categorized as an accident, will be adjusted to the incident category upon receipt of the occurrence details.
** Under new reporting requirements the minimum reporting threshold for incidents (200 liters) involving the release low vapour pressure flammable liquids has been harmonized with Part 8 of the Transportation of Dangerous Goods Regulations.
