D W Rogers & Company 0-4-2 Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class Enterprise (Locobase 11750)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 9, p. 94. Works number was 4620 in April 1879.

Locobase can't reconstruct this tiny wood-burner's career beyond Gene Connelly's note that the engine was later sold to Gadsden Furnace Company some time after that company's founding in 1887 in Gadsden, Alabama. The GFC was at one time the largest coke furnace in the South.
