I am glad so many bits of info are shared on the model forums, I have been reading back-threads on other forums and found a link to here. I'm a retired carpenter with a small grass fed beef operation and am planning a permanent layout for a wing of my basement to be able to build stuff in our long winters. I've been told my plans are ambitious, but here goes a quick outline. With a sawmill and small cabinet shop, I can't see buying pre-made bridges etc I have experimented making my own ties and structural shapes, Box beams and I beams in HO. I am going to use home made cabinet boxes, with the side panels made 4' high to hold a spline system made from my own 1/4 lumber. The space above the normal three foot high counter will be access for wires , staging areas, etc, and the Fascia will then cover the area above the cabinet drawers. I'm going to use mini-air cylinders from Clippard to operate the turnouts and any other actions I can. I'm building a small, 4 car ferry from a paper model plan, out of wood veneer, and have it move on it's own powered cart across to the other side of the layout. The ramp to the ferry will be raised and lowered by small air cylinders I'm planning an air operated hump yard and will use puffs of air to control the speed of the cars. I'm going to model a small logging operation and have a wood chip to power plant function with a rotary dumper operated by air cylinders. I'm going to handlay track and use a walking cab plan with DC engines and separate blocks Each small specialty area will have its own cab so several people can operate together I know this is a lot to take on but my interest is having a lot of action, and get local kids involved in the hobby. One of the lessons I have learned in reading so many threads is the wide range of specialties in this "sport" From super detailed rolling stock to operations to layouts; really fascinating tangents. My proprietary line will be called Skyview Lines and will use a color scheme I have used before for our farm. It will be a hunter green on the bottom like hills, with a medium blue sky above and white letters. Most of the building will be next year but I'm working on some of pieces such as bridges and the ferry as my research gets finalized. I am getting some detailed info on bridges and will soon start a 150' double track Pratt Truss bridge from my own cherry lumber (tight grain, easy to machine)(Walnut works well for ties, open grain and brown color, ready for a little weathering) Thanks again fro the info, I recently read about matching DC engines on this site and found the technical explanations fantastic.
