Minneapolis, St. Paul, & Ashland 2-8-0 "Consolidation" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 2621)

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.
