Lady Ensley Coal & Iron 2-6-0 "Mogul" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class Martin Ensley (Locobase 11599)

Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Vol 15, p. 44. Works number was 9906 in March 1889. Details on Enoch Ensley's rise (and fall) as the first major steel baron in Alabama found in [], last accessed 14 August 2010.

The Martin Ensley supported the first major steel-making operation in Alabama, the progenitor of what would become a significant steel center in the US. As he gained control of various existing blast furnaces under the umbrella of Pratt Coal & Iron Company, says the Encyclopedia of Alabama, he created enemies who eventually used the rival Tennessee Coal, Iron & Railroad Company to gain "underhanded" control of the PCIC in 1886.

Although Enoch Ensley was chosen president of TCI, his business ventures encountered a series of reverses. So his opening of 4 new blast furnaces in January-April 1889 was his last hurrah.

The Martin Ensley later worked for the Sloss Sheffield Steel & Iron Company, also in Birmingham.
