Red River & Gulf 4-4-0 "American" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 104 (Locobase 14298)

Data from DeGolyer, Volume 62, pp. 84+. See also Mississippi Rails' entry on the RR&G at . (Thanks to Everett Elueck, railroad operations director of the Southern Forest Heritage Museum in Long Leaf, LA, whose 15 February 2015 email to Wes Barris and Locobase corrected the original comments.) Works number was 532207 in August 1919.

The spine of Crowell & Spencer Lumber Company's Red River & Gulf Railroad was the 50-mile line from Long Leaf, Lousiana northwest to Kurthwood, hard by the Texas border. Locals 1 and 2 (1 southbound, 2 northbound) made fifteen stops and took 3 hours 20 minutes to cover the route. Frames and springs were made "extra heavy" to cope with the rough track.

According to Mississippi Rails, less than a decade later, the RR&G retired the 104 in January 1928 and stored it for 18 years. In 1946, the 104 went to the Comite Southern of Amite, La as their #1. Louisiana Eastern of Shiloh, La acquired the 1 in 1950. Ultimately, it wound up on the Stone Mountain Scenic Railroad as the General II in October 1961.
