There are historic maps here that can be downloaded (after purchase), or can be viewed online. The format includes GEOTiff which can be imported into TransDEM for geolocation on top of DEM files.
It's interesting to see some of the details put in on these maps including landowners, railroad companies, long-gone rail branches, and even horse railroads.
I've found them useful for locating rail yards that have long since been wiped out, and don't even show up on topographic maps that came out shortly these were originally published, and don't even appear in aerial photographs we have today.
