Railway Investigation R15H0013

Derailment and fire of Canadian National crude oil train near Gogama, Ontario

The occurrence

On 14 February 2015, a Canadian National (CN) crude oil unit train was proceeding eastward on CN's Ruel Subdivision near Gogama, Ontario. The train crew was composed of a locomotive engineer and a conductor. The train was equipped with 2 head-end locomotives hauling 100 Class 111 tank cars, 68 loaded with Petroleum Crude Oil (UN 1267) and 32 loaded with Petroleum Distillates (UN 1268). The train was 6089 feet long and weighed 14 355 tons.

At about 23:50, while travelling at 38 mph, the train crew felt a heavy tug on the train and a train-initiated emergency brake application occurred near Mile 111.6. Subsequently, the crew observed a fire about 10 cars behind the locomotives, so they detached the locomotives from the train. The temperature at the time was -31°C and a slow order (speed restriction) of 40 mph was in place.

TSB investigation process

There are 3 phases to a TSB investigation
  1. Field phase: a team of investigators examines the occurrence site and wreckage, interviews witnesses and collects pertinent information.
  2. Examination and analysis phase: the TSB reviews pertinent records, tests components of the wreckage in the lab, determines the sequence of events and identifies safety deficiencies. When safety deficiencies are suspected or confirmed, the TSB advises the appropriate authority without waiting until publication of the final report.
  3. Report phase: a confidential draft report is approved by the Board and sent to persons and corporations who are directly concerned by the report. They then have the opportunity to dispute or correct information they believe to be incorrect. The Board considers all representations before approving the final report, which is subsequently released to the public.

For more information, see our Investigation process page.

The TSB is an independent agency that investigates marine, pipeline, railway and aviation transportation occurrences. Its sole aim is the advancement of transportation safety. It is not the function of the Board to assign fault or determine civil or criminal liability.
