Data from Catalogue Descriptive of Simple and Compound Locomotives built by Brooks Locomotive Works, Dunkirk, NY (Buffalo, NY: Matthew-Northrup Company, 1899. Works number was 3161 in March 1899.
Described in the catalog as a logging Consolidation, this engine went to the Minneapolis, St. Paul, & Ashland (Wisconsin) Railroad. This railway was indeed a timber line that operated between 1897 and 1912. By 1904, the MStP&A had 49 miles (79 km) in operation. By 1908, all but one mile of line had been abandoned.
The front truck seems a fair distance in front of the first driving axle. A photo also shows an unusual wavy "running board" over the tender trucks.
