In this episode, I describe how to choose and research a prototype railroad. The most important take-home message I can give you is that you should never underestimate the value of some good in-person research at a historical society or university library.

The website I reference in the episode is thusly: https://geonames.usgs.gov/apex/f?p=262:1:19084355468963::::: and contains a complete archive of all the USGS maps ever recorded. Just search by state and quadrat name, and you will get a downloadable list of the files for maps made of that area.

Also please visit the links page of the website, which has a new, very detailed section on resources prototype research.
