A defective rail caused a CN train to leave the tracks, dumping oil into a popular Alberta lake two years ago, according to the final report by the Transportation Safety Board.
The derailment, which led to an environmental charge against CN, spilled more than 700,000 litres of bunker oil and other chemicals into Lake Wabamun, 50 kilometres west of Edmonton, in August 2005.

A 12-metre section of replacement rail had at least 13 defects that went undetected before the derailment, said George Fowler, a track specialist and TSB investigator, at a news conference in Edmonton on Thursday.
Fractures in the faulty track, installed in 2003, grew until at least one broke, sending the train onto the shores of Lake Wabamun.
The safety board made three recommendations in its latest report:
The report also said weak emergency response plans by both CN Rail and the provincial government contributed to the impact of the spill.
Residents of the village of Wabamun who feel CN did not respond quickly enough to the spill had called for similar recommendations.

On the second anniversary of the spill in August, health officials warned boaters and swimmers to stay away from oil patches and tar balls still in Lake Wabamun.
E. Hunter Harrison, CN Rail's president and CEO, did not respond directly to Thursday's recommendations, but praised the "throrough investigation of the unfortunate accident."
In a news release, Harrison said: "I'm pleased to say that CN, as the report notes, has already taken many steps to reduce the risk of recurrence of accidents of this nature, and will continue to do so together with government and industry experts."
In June 2006, Alberta Environment charged CN Rail with failing to take all reasonable measures to remedy and confine a spill, an offence punishable by a maximum penalty of $500,000. The case is not yet resolved.
The TSB said 75 trains have derailed in Canada in the past 10 years because of worn-out rail.
Can you say "indictment?"
This news is not unexpected, and it is most disappointing (or should be) but it won't create a ripple in the Canadian Public's worldview.
Sad.
