I think i'll mix the two. The red track i think will have to take an immediate dive into a helix. The blue track though i think i can slowly transition it down then get it into a helix under the automobile transfer facility at the top. Hopefully though i can get longer staging tracks then just 5 feet. Maybe i can use some stub ended tracks. I was hoping to have SD60Ms and C40-8Ws double headed and with a respectable train behind them.
