Double Track Helix Question

BillYo414OGR Forum Member SUPPORTING MEMBERDIGITAL SUBSCRIBER

I've been searching for info on the forum on building helixes (helices?) since there's one in my future. Why do I see a recommendation for a double tracked helix all over the place? Nobody seems to really says why you need one but a number of people insist you do. Traffic is the only reason I can see. Is it that simple?

I'm looking at an 0-72 single tracked helix to travel about 24 inches vertically. The mainline is double tracked but coal drags and passenger service are the only competition I can see for the helix so I feel that double tracking the helix isn't necessary. A train would simply wait until the other passes.

I want to stick to the plan but I know somebody has walked this road before and they might know something that my hubris overlooked.
