GATINEAU, QUEBEC -- (Marketwire)
-- 03/24/09 -- The Transportation Safety Board of Canada (TSB) today
released its final investigation report into the April 23, 2007
train derailment in Trail, British Columbia. The Board is satisfied
that improvements made as a result of its investigation will help
ensure that trains can safely descend steep mountain grades.
During the course of the investigation, Transport Canada issued a
Notice and Order requiring that crews operating trains on the 4.1
per cent grade between Warfield and Trail ensure that brake pressure
retainers are functioning properly and set correctly. The Canadian
Pacific Railway (CPR) has since amended its procedures to comply.
Additionally, Transport Canada agreed with a TSB Rail Safety
Advisory regarding the absence of the dynamic brake holding feature
on both locomotives involved in this derailment. As such, Transport
Canada is proposing a regulatory amendment to require that
locomotives with a dynamic brake holding feature be operated on
territories with a grade of 2 per cent or greater.
On April 23, 2007, a train with two locomotives, eight loaded hopper
cars and three residue tank cars ran uncontrolled down the 4.1 per
cent grade between Warfield and Trail. This led to the derailment of
the two locomotives and the eight hopper cars. A foreman and helper
had detrained before the derailment and sustained minor injuries.
The locomotive engineer remained on board and sustained fatal
injuries.
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.
