Peoria & Pekin Union 2-6-0 "Mogul" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class E (Locobase 8878)

Data from Peoria & Pekin Union 6 - 1925 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

This was Brooks works #4021 and came directly to the P & PU. Although a relatively robust Mogul, it was doubtless a misfit on this transfer railroad and was retired only 2 decades later.
