Signal Placement Schematic...

As we roll on with the signal install I realised quite quickly I needed a schematic that showed the layout in full so that I could work out the signal placement of the bridges & masts.

The ideal solution was right in front of me on the layout.  The fascia panels that I had made in Excel for the switch machine push buttons were ideal.

Over the last couple of days I have been sticking them together and working out the placement of the signal bridges relating to interlocking locations and the placement of the signal bridges, masts and dwarfs.

The diagram is perfect as I can reference the whole layout and even begin to figure out the programming of the signal logic as we go.

Even this schematic surprised me about how many signals are actually required to control the movement of traffic.  The system we will be using on the layout is mostly ABS through JMRI.  It will have the ability to hold aspects and manually set routes too.

Next step once I have the placement and number of signals finalised is to begin building the bridges, bracket masts, masts & dwarf signals.
