Hi, I have to build 3 or so relitively small trestles on my layout, the largest trestle in real life is about 500ft long and 100 ft high it was removed when i was about 12 and i cant find a good picture of it around here but i know they were pile trestles no cement foundations. The question i have is i read that 30ft is about the max height for pile trestles, would they have used 12x12 square post bents built on top of 12x12 pile bents for the high center section?? and would the piles be vertical with tapering square upper posts, seperated by a sill?
