Some years ago, preparing for a Colorado trip to explore the remains of the Rio Grande Southern, I discovered mapping, on Google maps, and started 'drawing' the RGS right-of-way, looking at satellite imagery, and pairing what I found with the old right-of-way maps in various RGS books.

 

I got a bit carried away, and started adding lumber branches, bridge locations, and other items. I took the trip, and it was helpful to find the actual locations. Then life happened and it sat. That was 2007.

 

Later though, Jim Marlette discovered it, and started filling in more details, and adjusting the accuracy of specific locations, and also filling some of the gaps. Then more recently, Don Bergman discovered it and spent last fall and winter making massive updates, especially by adding icons and photo links.

 

It's now a rather amazing resource - check it out!
