Richard Deuso had the incredible good fortune of capturing Montreal, Maine & Atlantic Unit Oil Train, as it made it's way eastbound, toward it's moment of infamy at Lac-Mégantic.
"At the TSB we hold by the theory that no accident is ever caused by one thing and it's always a series of things. And it always involves the organization. It never comes down to one individual." A number of steps have been, or are in the process of being completed.
The TSB has downloaded key information from the locomotive event recorder. TSB Media Staff began documenting brakes and controls on the locomotives, beginning at the site they came to rest about a mile east of the derailment.
TSB investigators inspected the tracks, and conducted a site survey, photogrammetry and videography to determine track grade and position, and this information will be used for future calculations and computer modelling.
Investigators have conducted mechanical inspections and photographed 22 tank cars to date to document accident damage. Sample pieces of the tank cars are also being sent to the TSB laboratory in Ottawa for further metallurgical analysis.
The TSB is conducting 3D laser imaging with the assistance of the U.S. National Transportation Safety Board (NTSB) to record three-dimensional data of the accident scene and different pieces of the wreckage. The scanner will be used to create full-color still images and assist in computer modelling.
