Mississippi Export 2-8-0 "Consolidation" Type Locomotives

Class 36 (Locobase 9494)

Data from NdeM 1946 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. 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.
