I recently went to Quebec City. I noticed two SW engines, possibly SW1200s or SW1500s working outside the Papiers White Birch plant by the VIA station. These were not Quebec-Gatineau and not in their yard because 1500 was in that yard. But one of the engines was blue with yellow markings near the top of the hood. The second engine was a green engine. The blue engine was sitting and I did not witness it move. But the Green engine was shunting CN high-cubes near the highway on the approach to the city of the Chemin de fer Charlevoix. If anyone could tell me who owns these engines, there numbers, and makes, it would be great. If you know anything at all, it will be beneficial. Sorry no pics. Thank you.
