Wisconsin Steel 0-4-0 Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 8 (Locobase 8486)

Data from http://www.irsociety.co.uk/Archives/60/Baldwins.htm (accessed 1 June 2007), archiving an article by Rodney Weaver, "Steelworks Baldwins", Industrial Railway Record, No.60 (June 1975) - pp 52-54. See also DeGolyer, Vol 73, pp. 303+. Works number was 58366 in April 1925.

Weaver tells us that this industrial saddle-tanker had the usual attributes: Stephenson gear, slide valves, air brakes and electric lighting. To highlight the size difference between American and British locomotives with similar duties, the caption under the photo reads, in part:"...A typical Baldwin industrial locomotive of deceptive dimensions it was almost identical in size to a GWR 5700 class pannier tank, which would be considered a large industrial locomotive in Britain."
