The Transportation Safety Board has announced it is opening an investigation into a runaway train incident earlier this month at CN Rail’s MacMillan Yard in Vaughan, in which 74 rail cars — one of them carrying dangerous goods — rolled away uncontrolled for five kilometres.
The TSB tells CBC News that on June 17 ground crews were using a remote control device known widely in the industry as a “belt pack” to assemble a train when the 72 loaded cars — as well as two empty ones — rolled away uncontrolled.
In a written statement released Tuesday afternoon, CN confirmed a runaway locomotive escaped its control and pulled the cars five kilometres down the track with a crew member stranded onboard. CN also revealed that the runaway cars included “a single dangerous goods load of an ethanol/gasoline mixture.” The company says it is co-operating with the TSB investigation.
