Ok guys im planning this layout now and have just wanted to see what ideas I could get with all your minds put togather. Its going to be a line from mid Penn ST up to Olean NY in which im told needed helper units to pull the grade. This will work out great since from the lower level to the top will give me a reason to have a Bunch of locos sitting around just waiting to give a hand on the steep grade up to Olean NY. Now I was looking at a system map and there is a East West line running threw Olean Ny with a wye and all. Very nice to have Google maps to give us a hand at looking at whats really there. So that will give me a nice Interchange with another line on the top level. The Helix and the Tracks leading to it are in the back room and will be hidden to the view of the operator. I will also have 4 or 5 track stagging yards at both ends of my points. Id like to see a nice interchange and Yard up on the top level at Olean NY and wanna build a nice Bridge on the bottom level threw the curve. I was thinking the ME steel bridge but have starting to think about a scratch built Concrete viaduct. here is a idea of what kinda area im looking at. The area which the front will sit is almost 11 feet long the narrow end is just under 1 foot and the curved area is 3foot wide. Also that 2xcrossover isnt cast in stone maybe just have one on the top level in Olean. Oh ya Im going handlay the track on the front side of the layout and use Atlas code 83 flex track in the hidden areas. Please guys let me know what you think.
