The Transportation Safety Board (TSB) says alcohol was a possible factor in a serious collision between two trains in Prescott, Ont., two and a half years ago. The Transportation Safety Board found a rail traffic controller based in Edmonton had an elevated blood-alcohol level when he allowed a track in Prescott, Ont., to be switched, leading to a head-on collision between two trains. Three crew members were injured, one seriously, in the head-on crash on the morning of Sept.
2, 2021, when a CN freight train pulling 202 double-stacked container cars crashed into another CN train consisting of two engines. The TSB investigation released Wednesday found the rail traffic controller (RTC), who was stationed in Edmonton at the time of the collision, had an elevated blood alcohol level hours after the crash
