So I finally had a chance for some extended running and I have found one small issue with the ride height and bolter pin. So I was having an issue with one of my cars derailing when it when over one of my switches. What I found is the trucks was riding to low and the axle of the wheel set over the coupler box was rubbing the coupler box and screw and the trucks did not have enough up at down movement so it was causing the car to derail. I also found that the bolter pin was too small ant it cause the truck to sit too loose at the bolster. So I replaces the bolster pin with an MT standard bolster pin and watcher and this solve my issue.
