Signalling at Hampton Court Junction
The proposal states that Hampton Court Junction signalling system control should be implemented in stages.
Six stages of development have been identified, and the signalling designs relate to those six stages.
The stages are:-
Mechanically re-build the lever frame, test lever frame mechanical function,
install associated pneumatic air supply for the locally worked points, and test.
test and commission the electrical lever interlocking
Stage 2 - Alps Line Junction
Implement control of the Alps Line Junction
Comprising 1 set of points, 2 coloured light signals, and 1 associated shunt signals
Stage 3 - Tunnel Junction
Implement control of the Alps Line Junction
Comprising 1 set of points, 2 coloured light signals, and 1 associated shunt signals
Stage 4 - HCJ Roundhouse Junction
Implement control of the main roundhouse junction
