In an undated photo, a locomotive passes through one of the many rock cuts near Pass Lake Station. Pass Lake was located at Milepost 120.6 of the Canadian Northern Railway Nipigon Subdivision and later Canadian National Railways Dorion Subdivision. In 1960 it became Milepost 170.3 of the Canadian National Railway Kinghorn Subdivision.

While an exact identification is very difficult due to the resolution of the photo, it appears to be a CNR 3200 locomotive, possibly 3281. If correct, #3281 was a Class S-1-b 2-8-2 Mikado built 1916-1917 by the Canadian Locomotive Company for the Canadian Government Railways. The boxcar visible has what appears to be Canadian Northern lettering, placing the photograph in the early 1920s.
