Expanded (Plus) layout for the Richfield

This layout was provided by Zandoz from the Trains.com forum. He very kindly improved the original KATO layout and made it MUCH MUCH better. Here it is: Click on the image below to show the full size layout:

The first thing I'd do with your extra space is expand all the curves up one Unitrack radius. As is, the majority of the curves are 11"r on the inside track and 12-3/8"r on the outside of the curves...that 11"r will really cut into what you can run, especially in the viaduct sections. Also, where the curved viaduct sections connect to the bridge, you want those curves a broad as possible. You can, go with the 12-3/8"r on the inside and the 13-3/4" on the outside for most of the curves without seriously messing with the plan allignment.
Since you have the added length, I'd expand the squarish section of the plan (the left loop) in both directions, and move that double crossover down to the front stretch, with at least a 7-5/16" straight on either side of it. As drawn, the plan has some potentially problematic double S curve situations with the double crossover immediatly coming out of a curve. This also give a bit more room for longer yard tracks in the interior of the loop.

WOW! Thank you very much Zandoz!
