I’m well along in making a bridge using Bob’s downspout and styrene approach. Might finish it this weekend
Now I’m thinking of making a viaduct for the elevated sections. Right now they are just supported on ladder trackbed. I was thinking maybe of using that 2 inch insulating foamboard and skinning it in concrete. At jim strong’s woodland railway he has buildings and a bridge done that way that are twenty years old and in great shape
Anyone have any experience with that method?
