Pacific Flyer 0-6-0 loco spins wheels on incline. Better traction suggestions?

Those metal plates are there for a good reason.  Yes it may the car lighter, but you will also have more derailments.

True, I was expecting this as a side effect and I tested. So far, not one derailment in at least 3-4 hours of continuous run, even at full speed.

Great info all, thank you!

Keep the car weights.  You may want them later. Longer trains on curves and switching operations will require them.

Absolutely, all kept, just in case!
