I see you have 2 crossovers behind the scenes, one on the green track and one on
the yellow. I like the way it enables you to put more tunnel portals in view of
the audience. Of course turning round in a small space is essential, not
something I can do on an 8mm scale layout!
Do you have a particular scheme for supporting the scenery (such as 1 brick
every 8 studs), to give it sufficient strength?
Could you post some pics of the inside of the mountain to show how you've
supported everything, especially the high level tracks inside (given the weight
of the trains). I'd like to develop a scheme for supporting scenery that uses
no more bricks than necessary yet provides sufficient strength to resist
handling shocks and the dynamic loads of trains passing.
Up to now I've done a few 48x48 modules by making the edges from 2-wide bricks
and building internal supporting arches towards the middle. The inside is
effectively a 3-arch bridge across the module, with 3 tracks going at right
angles, supported on each of the arches.
I've looked at a few pictures of scenery online and thought them a bit flimsy,
so I'd be grateful for any tips.
