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