There is a meaning and a purpose. He goes up here to move railcars to the north yard. It's either for storage or like Gavin said. CP G61, the train that runs the brockville sub at night and very rarely day time. Would come out to gran railcars and go back to Smiths Falls. But he can go in the south yard too so i'm guessing they are moving it up to storage. Yes it happens often. I saw it before 2-3 times. Even 586 and 585 use it (the freights that work around Brockville)
