Looking for double dog bone layout

[Doc Holliday]

When I constructed the original Bovee' & Defiance (BAD) Western, I made a rookie mistake in that it was a free standing 7' x 11' "L" shape with each leg about 4' wide. It was WAY too deep to reach across. It was in my basement and, having plenty of room, I thought why not? I'm now embarking on the BAD Western 2 which will most likely be limited to a 24"-30" deep shelf type layout, about 6'x10', in a shared room. I'm more into scenery than switching and am looking for an interconnected double track dog bone plan. As the name suggests, I'm modeling the Old West and plan on having a couple of mines in each of the end turn-arounds and would appreciate any suggestions or advice.

Thanks
