A word of caution: American Models turnouts are set up for Flyer/HiRail flanges. If you're going to be running with scale wheels, the turnouts will have to have shims added to the guardrails.
The exact details escapes me right now and I haven't been able to locate the modification. However, American Models will perform the mod at time of purchase for an additional $8.00 per turnout.
