Basin & Range is a truly awesome map so awesome that it is the only map on this site not to use the SAM format. Instead it uses an installer, two actually one is the map and the second is a patch. The 7-zip file included in this post contains four files, all four must be uncompressed into the same folder. Just like with a SAM you must have the “My Games/Sid Meiers Railroads!” folder empty. Once you have done these steps simply luanch the exes and install the map. Note a DOS window will open, do not be alarmed this is simply the program for extracting the files.
