Mississippi Export 2-8-0 "Consolidation" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 36 (Locobase 9494)

Data from NdeM 1946 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers 29323 in October 1906 and 29386 in November.

It's not clear exactly to what corporate entity this pair of Consolidations was delivered in 1906. The current-day Mississippi Export shortline site has a good summary of all the different identies assumed at one point or another by this Moss Point-based railroad. (http://www.mserailroad.com/history.php, last accessed 24 August 2008). It was known variously as

The Moss Point & Pascagoula Railroad (1894) - 4 miles from Moss Point to Pascagoula.

The W. Denny Log Road (1902)

The Pascagoula & Northern Railroad: "Peanut Route" (1906-1912)

The Pascagoula-Moss Point Northern Railroad: "Poor Man's Perfect Nuisance" (1912-1914)

The Alabama & Mississippi Railroad: "Agony and Misery" (1914-1922)

The locomotives had varied histories, too. Both went to the Atlanta & St Andrews Bay in 1936 as 200-201. 200 was later sold to Marine Junk for scrap. 201 was sold to the Gainesville Midland, which in turn sold it to Georgia Car & Locomotive, which sold it to the Nacional de Mexico as their lone G-21.


Class 38 (Locobase 11965)

Data from NdeM 1950 Locomotive Diagrams Standard Gauge supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also Mississippi Rails' entry for the ME railroad at http://www.msrailroads.com/MissExport.htm; and DeGolyer, Volume 64, pp. 307+. Works number was 53238 in May 1920.

This locomotive was originally to be called the Mina Carlota and bear the number 2. Its operator was to be Cuban-based Davison Sulphur & Phosphate Co. But the chemical company's Cuban pyrite mine, which was to open in 1921, did not. According to Davison, the Cienfuegos, Palmira & Cruces Electric Railway and Power company made it difficult to transport DSPC's ore to the docks.

Davison did not accept the locomotive and it languished in storage for 18 years. In 1938 Baldwin sold it to locomotive recycler/reseller Birmingham Rail & Locomotive. BR & L found a buyer in this Moss Point, Miss operator.

After four years, the MER sold the 38 to the Nacional de Mexico, which placed it in its own class G-21 and numbered it 1220. It ran until its retirement in March 1957.
