In an effort to speed up the switching process (I think). A CN freight train derails on ONR Track in Cochrane. I've seen CN do this a few times, If the majority of the train is North Bay bound, CN would bring the train over to ONR Track at Cochrane Jct. The CN GP9's would then uncouple at the transfer at the east end of the yard and let the ONR Yard Engine push the cars into the ONR Yard.
