EXCELLENT ON-LINE HISTORIC MAPS OVERLAY TOOL:

In addition to the historic maps presented below, if you are interested in overlaying historic maps onto current maps, the United States Geological Survey has provided an excellent resource for doing that.  Many of the historic maps that can be overlaid at that website show the Birmingham Mineral Railroad (usually as “L & N Railroad”), and the overlaying capability will enable you to see where it ran in relation to present-day maps.  Visit the USGS Historical Topographic Map Explorer website at http://historicalmaps.arcgis.com/usgs/  The following are INSTRUCTIONS for using that online map overlay tool:

USGS HISTORIC MAPS OVERLAY
If you are interested in overlaying historic maps onto current maps, the United States Geological Survey has provided an excellent resource for doing that. The overlaying capability is handled automatically by the website and will enable you to see how things appeared and where railroads ran historically (often back to the late 1800’s) in relation to present-day maps.

In addition to the easy-to-use tool that will overlay the USGS historic maps onto a current map, you also can adjust the transparency of the old map to compare it (see through it) to the current map locations.

The online resource is free at the USGS site and does not require registering or signing-in.

Below are the link to the USGS website and the instructions for using it.

USGS Historical Topographic Map Explorer

INSTRUCTIONS:

A. After you type a location in the search box (for example, Bessemer, Alabama) and bring up that current map, you will need to choose a spot on the map by clicking on it.

B. You can zoom in closer using the mouse wheel or pan around to find a specific location.  You can move the map around with the mouse (or your finger if you are using an iPad, but transparency does not work on older iPads).  You also can zoom in or out to help find a location using the mouse wheel (or finger-pinching on an iPad).

C. When you click on the map at a spot on the map you want to view (or tap a spot with your finger on an iPad), red cross-hairs will appear. To change to another spot, just click (or tap) on that new spot.

D. After you get the red cross-hairs, all the old maps they have available to overlay for the location where your red cross-hairs are will be listed along the bottom.

E. If you click (or tap) on one of those maps, it will overlay it, and you can change the transparency with the slider bar next to the map image on the left side of the screen.  (As noted above, transparency may not work on older iPads.)

F. You may have to pick and choose different old maps to get the one with the best scale for the site you are inquiring about.

G. If you are tracing a railroad route and come to the edge of the historic topo map, continue on to the next historic topo map by clicking (or tapping) on the area past the edge of the former topo map, then choose again from the new list at the bottom.

NOTE:

Some of the older (1800’s) maps may not be as accurate for some areas as are current USGS maps; the historic maps after 1900 generally are more accurate.  In some instances, the older maps were not well geo-referenced.  They provide good information, but the features on the maps may not line up exactly with today’s features.  The very old maps are fine for using, but you may need to mentally shift them a little to line up with known features on the current map (for example, the route of a creek on an older map may be shifted a little from its true current course).
