Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 9518)

Data from the Twelfth Annual Report of the American Railway Master Mechanics' Association, May 13th-May15th, 1879, page 83.

Mr Sedgley of the LS&MS described tests between 7 wagon-top Eight-wheelers and 7 straight-boilered Moguls from Baldwin (Locobase 9517). Although Sedgley made something of the slight difference between the two types, there was not much to choose when the taller drivers of the Eight-wheelers are taken into account.

NB: Boiler pressure is an estimate and the heating surface of the tubes (no firebox area is given) is measured from the inside; water side area would be 8-10% greater.
