Re: Map of Colorado's Railroads

I think that a lot of us have a passion for mapping the old RR grades as well as some of the current ones. Tony Howe has done a great job of attempting to map logging railroads and spurs in Louisiana, Texas, Mississippi and Alabama (that I know of) using both GE and some 1940 era air photos. I do the same in one area of Louisiana using air photos, 1930-1940 era topo maps and if you can get access to the data, LIDAR. LIDAR is simply the best so long as you can distinguish between roads and the RR grades. One thing to remember, especially if you are trying to get into yards and such, that many yards were not static. Often times the yards would be rebuilt for a number of reasons and what you see at one time may not be what was there either earlier or later.

All I can say is to have fun and enjoy what you are doing.
