If you’ve never spent the time to read Tim Warris layout blog and story of why he created Fast Tracks its a very pleasant read. He did an amazing job building the terminal.
This page is part of the story, and shows how Tim built the complex track. [The same technique would work in G scale.] Fascinating. He used continuous raails and notched them where they crossed. The electrical issues must have been horrendous, if he really does use track power. In large scale I would stick to battery!
