I am doing research into my family's history and found your post. My grandfather is listed in this paragraph and I wonder if this is the same train.
This is a paragraph from web page:
In July 1915, Capreol became a divisional point when the first train, operated by a crew from the town, left Sudbury and travelled to Foleyet which was the end of the line at that time.
The crew consisted of William Metcalfe, engineer, Paul Gaurrau, fireman, Thomas A. Anderson, conductor, B.J. Barstead, brakeman, and Ernie J. Durand, brakeman.
