Moonman, I am not sure that I follow. The trestle is an overpass at 5". The track running left from the overpass is at a grade of 3% to the turnout that makes a crossover at the far left. The track running from the trestle going up (north) and curving to the left is at a 2% grade to the turnout at the very top making the crossover.
The track running underneath the trestle is at 0" and climbs up both directions at 2% to reach the turnouts that are at 2" elevation of the left hand side platform.
