Hello everyone---this is John r. from indiana, new guy, just getting into HO model trains after many years of other hobbies----just wish I had started this years ago---I have three steam engines and a diesel switcher at this time with three rolling stock and caboose and four pass cars--haven't started a layout quite yet , but very understanding wife says the trains are "cute' and wants layout in corner of living room! Iv'e been following Vipermans thread / pics of his layout and plans, looks great! The idea i had to get a bridge on my layout without using any risers or elevation was to cut a wedge into the layout board from the side, under and beyond the track at the edge, build down from the edges of the cut to create a canyon that is narrow at the bottom with a river thru it. Would this be feasible or not?
