Just an average guy with an overall plan. We purchased the largest basement available within our budget then started to clean out the space, paint the walls, laser a datum line, and hang 200 linear feet of module knees. Then, town by town, I added 8' modules like dominos as it kind of seemed fit. My plans were sketched on the back of a 11 1/2" X 17" enlargement and then got lost, so it then just grew organically, powered by memory and imagination. I am not so much an operator nor a looper. The RR purpose is to provide commuter passage to end of run towns and supply the merchants with fuel, building supplies and out bound shipping.
This was to be a meandering country connecting RR on one level with mild topographical features but I kept finding ways of adding spurs and elevations. Having a busy outside work schedule there were many days driving when my idle mind would conger up a new twist.
Now I am working on a fifth level running with 3r at 20" and 60" plus three levels of scale 2 rail between them.
Three dozen or more engines and about 130 +/- cars are more than sufficient to perform all expectations plus a string of RDC's and gas electrics.
1100 feet of track with about 95 turnouts and five TTs turned out to be a bit much, but it seemed to be a good idea at the time. Smaller is much better, really!
