The Transportation Safety Board says it is ready to compile its report about a fatal train derailment near the Alberta-British Columbia boundary last year.
A Canadian Pacific Railway grain train was stopped on a mountain slope near Field, B-C last February when it began moving and plummeted off a bridge.
A conductor, engineer and trainee were killed.
The safety agency says only the 13 cars and tail-end locomotive that remained on the track were recovered for examination.
No data could be retrieved from the recorder in the lead locomotive because it was too damaged.
