Chicago, St. Paul, Minneapolis, & Omaha Ry., (C.& N.W.) Class "M-2" 0-6-0 #46

photo taken Spooner Wis, Circa 1943.

# 46 is busily engaged in making up a freight train at the division yards at Spooner, Wisconsin. Trains made up in this yard might be going to any of four directions: North West to Itaska, (Superior), Wis. North East to Ashland, Wis. South West to Hudson, Wis. to connect with the main line for the Twin Cities, Minnesota. or South East to connect with the main line for Chicago at Altoona. All that remains at Spooner (as of 1997) to remind one of the railroad activity of bygone years is an eight stall section of round house minus tracks that is used as a warehouse, a sanding tower, and a single track leading to Itaska that may or may not ever be used as a tourist RR.

Note that the injector,visable in the cab window, is within hands reach of the fireman.
