This document occupied but half an inch in a file of correspondence over six inches thick "rescued" from trash bins during wholesale cleaning of railroad archives. From researching documentation such as this, saved by members of the "Fraternal Order of Dumpster Divers," the Santa Fe Modelers Organization is able to provide its members a great cross section of Santa Fe prototype information from which more accurate scales models can be constructed.
While reading through this document, prepared by the system's bridge engineer in Chicago, you will learn a great deal about bridges and locomotives operated over the entire system during 1950. It is interesting to note the organization of the railroad's operating divisions of the time and the types of motive power hauling trains over the divisions.
Our thanks to Russell Crump for providing the thick file and to Ed Dabler, P.E. for reviewing it in preparation of the articles contained in the accompanying issue of the Santa Fe Modeler. Russell, I really hope I can eventually put the file back together!
