I actually tried to make the bogeys turn separately on the lowboy and 8 axle flatbed and it caused massive issues and did not work as it was intended.. The current setup is the best I have been able to do, they just cant take sharp turns fast. you have to go slow on sharp corners just like with a real train. I will have to check the amtraks, I didnt have any issues when I took them around my layout with the steam train and I hit 50mph in spots.
