another concept plan

[steinjr]

Well.... we got the insight... lets see how this concept looks completed:







Its hard to tell from the profile... but there is some elevations going on here.

Okay - the profile view and the drawing of the lower corner makes your concept quite a bit clearer.

Forget pretty much everything I have said - your design goal seemingly isn't about realistic looking scenes or realistic operations for the CN and CP in the Canadian Rockies, which is what I was assuming.

What you are going for seems to be more of a toy store window display style layout where one (or possibly two) trains on autopilot will be crisscrossing it's own track multiple times at multiple heights through what you call "the mountain twisties", probably ducking out of tunnels and crossing bridges and viaducts. Kinda like a Disneyland version of a Swiss Alpine railroad - very fun, but has little to do with realism.

Cool - I bet it will be a lot of fun to build, and to show to visitors, who very likely will ooh and aah about it !

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) ?

Smile,
