I mentioned that Trevor Triplow has sent me some pics to share with you.

This one caught my eye ...
http://tdu.to/948-emergency-rope_1960s_TrevorTriplow.jpg

It post dates the union imposed ban on climbing on the roof to get the
pole back on the wire.
You can see the resulting 'emergency rope' on the pole and the driver is
apparently in the process of using it!

Mal Rowe - who reckons that there was still room for improvement in OH&S
at that stage.
