Maybe sprung drivers isn’t what I need. I have several steam engines I run on my layout and on a club layout. The Williams 2 rail and other brass locomotives run very well. I have two captured axle engines that are both converted Lionel engines. They both clunk on the switches and when coming off a grade. They don’t derail, but there is a noise and you can see the lead driver losing contact with the rail. One is a 4-8-2 the other is a 2-8-2. I’ve just assumed that was because of no springs on the drivers.
I was trying to avoid that with the All Nation engine. But perhaps that’s not how to fix it. Thoughts?
