Regardless of track used for the trolley, just curious as whether or not to ballast the trolley line. It runs about 20', starting at level in a circle and at the end of the circle it rises for about 12 feet over other track and loops back around eventually returning to level again. In this situation, would it be customary to ballast the trolley track, which would require plywood sub-roadbed. Or, should it just be supported by trestles, no sub-roadbed and not ballasted at all ?
Also, with the rise in both the out and back directions, would the voltage need to be adjusted or can it be constant for steady operation ?
