The Zs and the As built with poles do still have the base.
It was deemed simpler to leave the base on to provide the necessary
electrical termination point for the electrical cables (Pic attached).
Once the pole was taken off the issue of pole short circuit to the
trolley hook was eliminated.
Mal Rowe - who has seen some of the bases when removed - they were
rusted solid.
