>>1540560When would broad gauge actually be practical in the modern world over standard 56.5 inches?
I can see NASA building a small 10 or 15 foot gauge network at Cape Canaveral specifically for moving rocket parts or even complete launch vehicle assemblies from storage to the launchpads, replacing the shuttle crawler that tops out at 1mph and takes 5 hours to reach the pad. I wonder what the locomotives would look like.
