This is not a full accounting of titles in the Library's collections or of what is available via the Internet. Sources like HathiTrust, Internet Archive, Google Books, and other projects and people interested in railroads have digitized some copies of the titles mentioned below. If you are looking on the Library's web pages, searching the words railroads and broadsides will return a number of timesheets from various railroads but what the Library has in print form and what it has digitized, do not cover all railroads or all years.
If you are looking for track charts, a source like multimodalways.org External has some by line, but not all lines and not any for many of the lines. There are other collections related to Union Pacific, BNSF, and the Atchison, Topeka, Santa Fe Railroad, etc. that you can find by doing a general search on the Internet.
