How to Build Bridges for Model Train Layouts

"On behalf of Expert Village my name is Bob Lanning. I'm here to tell you about making a train diorama in HO scale. Now, there are many bridges on the layout. You can see a couple of tressels there. They can be made by hand, I think most of these are scratch built, those are called tressel bents that are holding up the bridge. There are kits available to build these bents and we have a curved tressel and a straight tressel. These are historically correct for the era and they are not too hard to build you just have to make sure everything fits good when they're level with their surrounding track work. We like to put a little humor in with some of our figures and here you see a troop of boy scouts climbing a hill and they're unaware that there's a black bear following them up the hill. Another version applied in there you'll see a fellow sitting up the limb of a pine tree and the bears got him treed as you say."
