18b 750 crosses the bridge, heading east, March 1965, Dick Jones photo.
The gradient on the bridge is quite apparent from this view. Also, 750, along with 751, was fitted with automatic acceleration similar to Sydney P and Adelaide H classes. Unfortunately I was not aware of this until later, or else I would have made sure I had a ride as they were normally confined to these services and I believe I have a scene of one of them on movie. Eventually RC2 equipment was fitted, the PC gear going to SPER. I don't know the present status of that.
