The outside O48 route around the spiral comes in at 226", or 18.83 feet. Works out to about 2.55% grade using 8' (96") increments (Woodland Scenics inclines). If you were to make the run at 3% you get to 7" in height. With the hidden yard, I would go with 3% to 7" to give more room underneath for access.
