It was a bit of a challenge getting that homosote to co-operate. Pre-bending it helped quite a bit. There will be a huge, hollow mountain in the middle of this loop. I'll need to create an access panel inside that mountain for track maintenance in a tunnel going through the rear of it. There will also be tall, sheer, verticle rock faces on some parts, between the upper and lower tracks. The lower elevation loop will be extremely close to the edge of the benchwork, so I'll have to sculpt a fascia and take the scenery from the track up to the top of the fascia. That will prevent any derailment from hitting the floor. There will be some scenic challenges but I'm confident that I can work-around them.
