I posted here awhile back and wasnt really sure what I wanted. Thought I would let you see what Ive come up with. This is all new to me so I post my givens and druthers a couple of sketches of the room I have and a coal mining town I would like to model. Scale: HO Standard Guage. Era: Late 1930's Steam. Region: Kentucky Hills. Railroad: Kentucky/Tennessee. Space: 9' 4"x 11' 8" Rolling Stock: Coal,Freight,Passenger. Track/Operation: 80% Mainline Running: 80% Scenic Realism: 90% Switching: 50% Operating Priorities: Main-Line passenger train operation, Coal mine operation, Local freight operations. Min. Radius:18 degree maybe 15 degree. Max. Radius: 22 degree. Max. Grade: 2% Unsure. Power: DC for now. Primary Trackage: Flex and sectional. No duckunder if I can help it. Maybe a swinggate or Hinged liftout. The first pic of the room shows the bench work without the need of duckunder or lift gate but puts me with smaller raduis curves. The second gives me more room for the coal mine and town Im wanting to model continious running is a must. The grid squares are 12 inch. The next pic shows the mining town I could change the the structures of the town to fit the space i have. But the coal tipple and the bridge got me to thinking of maybe an upper shelf layout. I would want to keep the mine north of the tipple on the lower shelf. By the way on the track to the north mine I thought of using N scale track and scratching some mine carts (thought this might be importent) for any one helping me on a track plan.I would have the bridge going south lead up to the upper level for inbound train from other mines. But space might not allow this scenerio.
