Arkansas, Oklahoma & Western 4-6-0 "Ten-Wheeler" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 441 (Locobase 13246)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 31, p. 155. Works number was 32773 in May 1908.

The Virginia & Carolina originally ordered this locomotive, but it was sold to the AO & W. Amid the precision of most of the specifications for this locomotive was the comment that the chime whistle was to be "a good one". A bit subjective, one concludes.

Put into service as the Rogers Southwestern in 1906, the "All Off & Walk" eventually measured 30 miles (48 km) and connected Rogers, Ark with Siloam. A more commercially viable nickname was the "Fruit Belt Line", which saluted the fruit growers that were to supply the principal freight.

The AO&W was never really successful and merged with the Monte Ne railroad to form the Kansas City & Memphis. But that railroad also failed to generate enough revenue and was abandoned in 1918.

The 441 was sold to the Bolling Franklin Lumber Company. The BFLC later sold the engine to the W P Brown & Sons Company of Louisville, Ky.
