At one time CN's Warman sub was a vital part of CN's system, providing the main link to Prince Albert. Although it still serves this purpose today, most of the line has been sold to a shortline, meaning its a lot less vital then it used to be.
Due to "strategic downtown re-location", CN yards were moved south to the egde of town, while most industries, including the warehousing district moved to the north edge of the city. Great planning!
As a result there's much work to do for the Warman sub tramp job, which ussually consists of two GMD1u's and a caboose on the trail for tricky back-up moves (one such spur is in the foregound). Why tricky? Because no one respects the train on busy industrial streets. CN Police on occasion tagg along for the ride, that's how bad truck/train relations are.
The duo makes quite a sight hauling giant in comparison, autoracks back to the mainline, from the CP interchange located nearby.
Just like a Winnipeg tramp crew I used to follow around, this crew is out to lunch. The Tim Hortons cup between the rails is not set-up. This is likely the 630 tramp job, as in it starts @ 6:30am, well before sunrise in winter.
