Algoa Helix Calculation (from my Ideas Book)
I am waiting for forumers to comment on the above calculations. But, in essence, I am considering 16 inches effective radius to helix edge (to support 15 inches radius to track center) and a 2.5% max grade (Updates: Calculation okayed. Need to mock the helix and test the traction power of loco(s) and no. of cars it(they) can pull.
P/S: The Ideas Book is a great idea. I have jotted many notes there and handy to carry around. Do you have yours today?
