Incomplete communication led to risk of collision between a VIA Rail train and equipment at a CN work site in Whitby, Ontario, in October 2015

RICHMOND HILL, ON, 5 Oct. 2016 /CNW/ - According to its investigation report (R15T0245) released today, the Transportation Safety Board of Canada (TSB) has determined that incomplete communication and improper signal blocking were causal in the risk of collision between a VIA Rail train and work equipment at a Canadian National Railway (CN) work site in October 2015 in Whitby, Ontario.

On 25 October 2015, before a crew started work on a CN track of the Kingston Subdivision, near Whitby, Ontario, the foreman called the CN rail traffic controller (RTC) and asked for—and received—exclusive use of the south track (which meant that trains would be operating on the north track only) between Mile 304 and Mile 305. However, the RTC inadvertently entered improper signal blocking that would still permit trains to operate on the south track past Mile 304
