On my last layout I made the sub roadbed from 3/4" plywood and used biscuits to join the sections, no splice plates.  For supports I cut a number of 1 X 3's on a chop saw for consistent length.  Thee first turn was supported every 90 degrees and subsequent turns were only supported by the 1 X 3 supports.    No need for center frame work as Kieth has shown.
