Hi Ken,
I really am inspired by your layout. I am new to the hobby and feel that this layout provides the best amount of flexibility for multiple paths for the trains to travel throughout the expereince. There are two modifications I am thinking of incorporating and would really appreciate your help on implementing them. At the very top of the mainline I would like that area of track to be elevated as it is traveling on the right hand side I would like to incorporate a mountain where the trains wraps around the mountain on using outer curve.
Can you please educate me on what additional track pieces I would need to purchase? What grade should I strive to achieve and how?
Also on your existing layout what is the length of the passenger cars? I noticed on average you have 8 cars. Would you recommend 18" passenger cars or 21"?
Thank you for your time and all of your hard work you put into this amazing layout.
