Hi Rich
My club's elevated track consists of concrete posts spaced every 6ft, with
steel trestles spanning between them. The track is conventional steel FB
rail and timber sleepers, sitting on top of the trestles. To obtain
superelevation we pack between the top of the concrete and the underside of
the trestle, on the outside of the bend, about 1/8" on a 40ft radius curve
is sufficient.
Regards
Ron
