It's not pretty, but you can make some geography changes with SCARM using figures.
Thanks for the tips - I'll give it a try.
Now that you have changed the direction of the top set of yards so that it leaves the main line in a clockwise direction like all the other sidings the reverse loop isnt critical. You can now travel the mainline in a anti-clockwise direction and back into every siding, so it functions without it, but its still an interesting feature to have.
What everyone has been saying about having a hidden siding is valid not only for derailments but also so you can glance at a turnout and see which way it is set. If it cant be seen you need to wire up an indicator to tell you how the turnout is set.
I like the reverse loop idea, but I'm wrestling with the tunnel now. I agree with you all about the negatives that switch in there can cause.
Three options I've come up with:
1) Move the yard just to it's right a bit to the right and use a view block between the 'tunnel' switch and that yard rather than cover it.
2) Move the tunnel entrance above the switch.
3) Eliminate the reverse loop.
