hello, I am preparing my polar express layout expansion for around the Christmas tree this year. I did a rough mockup of a 3 to 3.5 ring helix that goes from 4.5" tall to 7.5" tall and then 9" at the end of the 30" straight to exit the helix. Interested in any opinions regarding if the final spiral is too steep a climb for the original polar express conventional (the non lion chief).
The outer ring is o48 and it goes inwards to 036
Also, will there be any issues when the curves go directly from 031 to 060 to 036
thanks in advance
