There are quite a few people/groups that have done a lot with very little recognition. The N&W Historical Society jumps out with it's decal line. Anthony has done amazing stuff at Signature Press. Prime Mover has limited sets but they appear to be top notch including their NYS&W stuff. The NP and GN historical associations uploaded ((thousands)) of structure elevations on their websites. I'm just scratching the surface, it just goes on!
