- Via derailment still haunts survivors.

The Toronto-bound train was travelling from the Ontario's Niagara region and switching tracks when it derailed near Burlington, about 60 kilometres west of Toronto, on Feb. 27, 2012.

The three engineers who died were riding in the cab of the locomotive, which toppled onto its side and slid into a building at the side of the tracks.

In all, 45 people were admitted to hospitals for injuries ranging from minor scrapes to a broken leg, a back injury and a heart attack.

The train was travelling at more than 100 km/h at the time it derailed, that's four times above the authorized limit for executing a crossover along that section of track.
