I didn't notice this scene.  Presumably it was one filmed in Rozelle Yard. 
If the pantographs had been fully extended while not under wires, the
effect would have been even worse.

Spinning occurs when a loco has more power than its weight is capable of
turning into tractive force.  Adding concrete ballast improves the
situation, and does not make it worse.
