Two and seven eighths inches high on the track, if that helps. (Three inches to be on the safe side.) Add at least half an inch for clearance, assuming your track and the overpass are flat and parallel to each other but more would be better! The trucks shown are the most common and therefore easier and cheaper to find second hand.
