Modbury - Signalling Diagram (Mark II)
I really want to get this as sensible/accurate as possible because it is my intention to use the signals to allow power to be provided/denied to the various track sections, effectively engines will only get power if the correct signal(s) have been Cleared to allow entry into the section.
To this end, I have come up with the following :
I still have a few items to iron out, which hopefully I can do by referring to prototypical GWR Signal Diagrams. For instance a train given "Shunt Ahead" rights in the Down (to the left) direction, would a ground disc be provided by turnout (5) to allow the train to come back into the Down platform (especially since the turnout is beyond the road over bridge)? Similarly, I have provided a ground disc (11) by turnout (12) but can't decide which side of the track it would be sited - it is there to allow access into the Goods Yard/Up Loop by trains shunting in the Down (from the right) direction.
I have also been giving consideration to the method of wiring the connections to the Signal Actuators (Memory Wire). Luckily, I have the Model Railway Constructor articles on the P4 North London Group's "Bodmin" layout, where they have described the utilisation of relays to facilitate the type of operation that I want to achieve.
To this end, I have taken their ideas and produced an example wiring diagram for a short section of track with a couple of signals which I will now develop into a full wiring diagram once all of my track work has been laid (I have provided a fews comments for myself when I come back to this in a few months) :
Hopefully the diagrams are large enough for interested parties to read!
I look forward to receiving further comments (critical or otherwise)
