I came across this track a few weeks that I had built ages ago for the invert comp. I realised that it was actually better than I thought it had been when I'd given up on it so I started to test some colours, do some terraforming and start supporting. Remember that one of the rules was to have 3 trains running without stacking so I have kept this in, but have made a few little adjustments. It is hand built and this is my first time custom supporting an invert so feedback would be appreciated. Here are some shots:
