Class Details by Steve Llanso of Sweat House Media

Class 4 (Locobase 12802)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 27, p. 308. See also http://www.stjohnparish.com/grh/rails.htm, last accessed on 30 June 1905. Works number was 26316 in August 1905..

Described by the website as "...the flagship of the plantation fleet ...a majestic little 2-6-0 with full size tender, weighing twenty-six tons. this little engine proudly carried a brass eagle just below its headlight."

4 was delivered to the Reserve Plantation and operated for almost 5 decades before it was wrecked in 1955. It was scrapped in 1956.


Class 6 (Locobase 14337)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 53, pp. 310. See the Tap Line Case opinion on the GSW's operations at http://www.ttarchive.com/library/Articles/TapLineCase_GouldSouthwestern.html Works number was 41647 in August 1914.

The 1914 ICC opinion on this short line's operations rejected the appearance of an "entire absence of any community of interest between the tap line and any lumber company." Their conclusion about the 17.6 mile line between Parma (later Gould) and Star City, Ark indicated instead that "the facts appearing of record and disclosed by our own investigations by no means confirm any such assertion." In other words, differences in rates between those paid by the mill owned by Muse and higher rates paid by other independent mills were not accidental.

In the same year, the GSW was in receivership, but still managed to buy this small Mogul. In 1920. the line was reorganized as the Arkansas Railroad, of which it assumed control in June 1921.

A few years later, locomotive rebuilder/reseller Southern Iron & Equipment bought the 6 and sold it in January 1927 to Brownlee Lowry Company of Potters in Dallas County, Ala. The lumber company was coliquidated in 1930.
