This is the Suwanee quadrangle which includes Roswell, Alpharetta, Cumming, Duluth, etc. This is the companion to the Atlanta quad posted earlier.

Lake Lanier, a portion of which should be present here, was not impounded until 1956.
Another gem from the USGS store.
This thumbnail shows the long-abandoned Roswell Branch of the Southern Railway where it joins the main line in Chamblee. Click to get a much larger map covering a much larger area.
Notice that most of the Chattahoochee are still ferries on this map, rather than bridges. Holcomb Ferry is located more or less where Holcomb Bridge road is now, and so are the others.
The Eastern Continental Divide is rather easier to see on this map than on a modern map, if you know where to look.

Notice an additional rail line crossing the L&N, that I forgot to include on my map that I made with MS paint. This was the electric street railway. I have since edited that map to show it.
The explanation I tried to give about the abandoned tracks in Tuscaloosa in my last post probably makes more sense if you look at this map. Click the map to enlarge it.
For reference, this is the photo of the “approximate photo location”:
The main reference for the location of the street railway is here.

You can zoom and search and do all the stuff you are used to being able to do with an online map. You can see main lines (color coded by railroad), mileposts, station names, Amtrak, and even individual markers for each railroad crossing.
It mostly doesn’t bother to show sidings, branch lines, etc.
The station names are a bit.. off. Just in my area, almost all of them are at slightly different mileposts than the railroads’ timetables have, and some of the ones on the map appear to have been derived from a source other than the current timetable. I’m guessing the database they are pulling these from is not particularly up to date, and the railroads have moved them around and renamed them? Either that or they’ve just got bad data.We have found both situations where a line is shown without its mileposts, and also situations where the mileposts appear without the actual line they are on. (Mobile, AL has a notable case of the latter)But still, it’s the only free online thing I’ve seen that shows railroad mileposts on a reasonably accurate map.
