Arrangement of the Materials

The collection is arranged into the following series:

1. Freight Cars, 1925-1983
2. Locomotives, 1901-1999
3. Passenger Cars, 1907-1975
4. Shops, 1881-1984
5. Special Service Cars, 1937-1985
6. Tenders, 1940-1948

The collection is (generally) in alphabetical order by subject or personal name, then chronologically within each folder. A number of folders contain specific, labeled files (for example, as C-5-2384, C-8-396, etc.) bound together, whose documents are ordered from most recent to oldest in some instances and from oldest to most recent in others. Upon processing, when due to size, these bound and labeled files stretch over more than one folder, the folders are labeled with a, b, c, etc. after the folder number indicating that the documents in these files were originally bound together.
