Sharpsville & Oakland 2-6-0 "Mogul" Locomotives in the USA
Class Details by Steve Llanso of Sweat House Media
Class Oakland (Locobase 4378)
Data and letter from [
], which is an extensive archive of Western New York railroading documents, maps, photos. See also DeGolyer, Volume 5, p. 18. Works number was 2076 in February 1870.
In a 14 November 1878 meeting of the Board of the Atlantic & Great Western Railway, the Oakland was used as an example of how a Mogul could perform. Baldwin's supporting information included accounts of how the engine, "without slipping her drivers", pushed 18 loaded cars weighing 829 tons up a 1.6% grade, "gaining speed and steam as she went."
Mark Fischer transcribed the fascinating look at a deliberation over increasing locomotive power.
