Thompson-Wells Lumber Company 2-8-0 "Consolidation" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 15239)

Data from DeGolyer, Vol 71, pp. 405+. Works number was 56525 in May 1923.

Baldwin delivered several Consolidations of this design to sugar centrals in Cuba. Gene Connelly's magisterial Baldwin production list says that this engine was originally ordered by the Lake Superior & Southern. It was headed to relatively easy conditions where it rolled on 65 lb/yard (32.5 kg/metre) rail up modest 1% grades and around gentle 10-12 degree curves.

The 3 apparently wasn't the right engine because it was sold to locomotive rebuilder/ reseller Birmingham Rail & Locomotive on 14 May 1926. BR&L found a buyer in 71-mile ( 114 km) Midland Continental of Jamestown, North Dakota, but that long-lived railroad apparently didn't find the locomotive satisfactory either. Its resale to the BR&L in 1930 started a string of moves that included the other two major rebuilder/resellers. The BR&L sold the 3 to Georgia Car & Locomotive for sale to Industrial Lumber Company of Elizabeth, Louisiana. ILC operated the engine for about eight years before selling the engine to Southern Iron & Equipment.
