Curve-replacement and larger (above #5) hi-rail turnouts may present problems with scale wheels. Curve-replacements turnouts have a curvature extending through the gap in the frog and the wheels may pick the frog; the larger turnouts have a larger frog gap and the wheel my pick the frog while dipped in the gap. The MTH #6 is a bit different because the frog is ramped to catch the wheel, but may still pick from time to time. That said, we have a couple of O-72 turnouts in the through yard at the club (Ross) and at slow speeds, scale-wheeled equipment seems to go through without incident when pulled. My scale-wheeled locomotives (4-axle and my two steam locos) also get through at low speed.
For the #8 curved turnout on the mainline, we put a moving point within the frog gap.
