may i make a suggestion on lowboy can you make the bogeys turn separate form each other because they tend to derail on tight curves and on incline same for flat bed with 4 sets of bogeys if they all turned and pivetted up and down it would be smoother. also the older amtrak cars tip and bogeys fall off on curves with steam train. havent tested it with other trains yet. note not complaining just giving ideas to help make inprovements.
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.
