Peter,
The bouncing is actually fast angle wheel wobble. Fast angle wheels have a tendency to do that when they are being pushed. Lionel discovered this years ago during the MPC era when the introduced the GG1 with fast angle wheels in the pilot trucks. The front truck would wander endlessly as the engine was going down the track. If you change the wheel sets to postwar style wheels and axles or find a wheel set that is not fast angle, the "bounce" will disappear. I may be wrong, but a die-cast hopper would probably make the wobble worse because of the heavier tracking weight.
