Despite Regina being one of Canada's major city's and CN's lines sprawling in 5 directions, CN's presence is rather small: Always a GP38-2W on standby.
Today CN 1415, a GMD1u is paying a visit. Note the smoke coming from the smoke stack - he soon went to work. 4792 on the other hand is a Saskatoon regular, notice the double CN patch on its back.
After railfanning Winnipeg & Saskatoon for 5 years, I thought I've seen all the area GMD1u's by now, nope 1415 escaped me!
