I still really like the t-trak method, and intend to build my home layout one section at a time using t-track sections setup on top of the benchwork with scenes that can be mix and matched. Here's a peek at a first set of modules for a complete layout. There are some nonstandard shapes in here, but they follow the standard length dimensions either single, double, or quad. The two end caps connect to a permanent return loop behind the backdrop. The intention is to add passing sidings back there for staging.
