Question re new Bachmann Diesel

[nachoman]

The traction tires have probably dried out. Dried tires fall off easily. If it has traction tires, it is a "pancake motor" unit. For just running in a loop, they were okay. For slow running or switching, they were more of a pain. My brother had a bachmann GP30 that also had electrical pickups on the powered truck, and it ran much, much better than my F9 that had pickups on only the unpowered wheels.
