another concept plan

[steinjr]

Is it all one big loop (so only one train at a time can run on autopilot), or is it two independent loops (so two trains can run on autopilot at the same time) ?

It's one loop, a dogbone folded to make a double-track main. Note how the end loops in the mountain area are single track.

I believe this layout is an example of what John Armstrong called "the riata". Dogbone folded into a double-track main, large yard on a wye. In fact, it might be the first example I've seen of someone actually planning one.

"The lasso" ? LOL - one learns something new about layout design every day

Trainnut's yard looks cool, too.

Big grin,
