I presume by AES you are talking about  Electric Staff using auto 
exchangers which was 70 MPH where the track speed was 70 MPH.

Signalling systems & safeworking systems are differant where the signals & 
points are directly under the control of a train controller or where they are 
operated by a signaller under instructions of a train controller.
Where the signals and points are under the control of the driver of the 
train,and the driver of the train is under the control of the train 
controller,then the two are one and the same , ie the safeworking is the 
signalling & vice versa.
The only reason that the cressy plains line has the bizzarre arrangement of 
signals that it has is because of the safeworking system, ie the two 
are dependant on each other.

Anyway , with a bit of luk , it will all possible change from 1 July.
