The SBU data from MMA-002 were downloaded (Engineering Laboratory Report LP132/2013). The SBU data and crossing download data were used to corroborate the LER data. An analysis of the SBU data determined that when the SBU first recorded movement (start-to-move) at Nantes, brake pipe pressure at the rear of the train was 29 psi. Approximately 16 minutes and 40 seconds after the train began to move, the brake pipe pressure at the rear of the train had diminished to 0 psi.
For the right-hand curve section in the vicinity of the derailment, the superelevation (1 inch to 1 inches) corresponded to a balanced speedFootnote 31 of between 18 mph and 22 mph. An analysis of the derailment speeds estimated that 10 cars derailed below 40 mph, 5 of which derailed below 30 mph (Engineering Laboratory Report LP039/2014) (Figure 5). Recorded data showed that the derailment took approximately 1 minute (Engineering Laboratory Report LP136/2013).

Three-dimensional (3D) laser scanning was performed on selected derailed tank cars (Engineering Laboratory Report LP165/2013). Analysis of the data revealed that the shells of the tank cars exhibited impact damage ranging from localized buckles to large-scale buckling, and sustained significant reductions in volume (for example, close to 40% reduction in volume was sustained by the most deformed tank) (Photo 16).
On 26 August 2013, the TSB sent Rail Safety Information Letter 16/13 to TC regarding the crossing condition at Agnès Street in Lac-Mégantic. On 27 September 2013, TC advised the TSB that the Ministry of Transport of Quebec was planning to replace the crossing surface in the fall to address the reported unsafe condition at the Agnès Street public crossing. Subsequently, the Ministry of Transport of Quebec made a temporary repair to the road surface by adding asphalt where the road crosses the main track; the spur leading to a local industrial facility was covered over with asphalt, as it had not been used for 2 years.
