Data from Peoria & Pekin Union 6 - 1925 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.
The diagram book says this little Eight-wheeler was built at the shops in 1915. In fact, it was REbuilt by the shops from an 1879 Chicago & North Western locomotive (numbered 352 by the C&NW)..
