This logging line to the southwest of Alexandria, LA, extended in 3 directions from Long Leaf Junction on the Missouri Pacific (now UP). One line went from Long Leaf Junction to Forest Hill, Holdup, Togo, and then LeCompte on the Texas & Pacific (later MP and now UP). To the southeast of Long Leaf Junction, the line went to Long Leaf, location of a major saw mill complex which is being preserved (see below), then Louisiana Junction, Audebert, Cocodrie, Causey and ending at the Rock Island in Mederain, also a sawmill town. To the northwest, the RR&G went to Big Cut, Melder, Bliss, Elmelhine, Lewiston, Walding, Stille, Hood, Comrade, Mathis, Hutton, Alco, Dusenbury, and ending in Kurthwood. The line was apparently built for the sawmills it served.
In addition to Everett Lueck's photos, Steve has provided some pictures of a historical marker at Peason, LA, which shows some of the RR&G operations in the area, along with some more pictures of the rail equipment at the Southern Forest Heritage Museum. For more information on the railroad equipment or for the RR&G in general, please see both the Museum's website, and Steve's blog, both linked below.
Thanks to Everett Lueck for contributing information about this route.
