Class Details by Steve Llanso of Sweat House Media

Class 17 (Locobase 14054)

Data from Baldwin Negative 4978 as digitized by the DeGolyer Library of Southern Methodist University and archived at http://digitalcollections.smu.edu/u?/rwy,320. Works number was 41296 in April 1914.

When the ALC had extracted more than 20 years of service out of this typical Baldwin logging Ten-wheeler, it sold it to the Reader Railroad of Reader, Arkansas. The Reader later sold the engine to Meriwether Gravel Company.
