Canada's Transportation Safety Board is shedding light on how the locomotive from the Lac-Megantic disaster ended up at a US rail yard where it nearly went to auction.
The lead engine in last year's deadly derailment was shipped to the Maine facility after the agency tested the machine and removed key components for its investigation.
Spokemsan Jean Laporte says the TSB asked the Montreal, Maine and Atlantic Railway to store the locomotive on its behalf until the completion of its investigation.
Last month, the SQ was forced to make a sudden request to block the machine from being auctioned off because criminal proceedings were still going on.
The TSB is set to release its final report on the disaster tomorrow.
The tragedy killed 47 people and destroyed part of Lac Mégantic's downtown.
The defence lawyer for engineer Thomas Harding has said his client's trial on criminal-negligence charges could have a ``major issue'' because what is likely an important piece of evidence in the case was allowed to leave the jurisdiction of Canadian authorities.
