I've been able to start building the prototype signal control circuit for Hannerton. Once I'm happy that it functions as required I'll build it for real on the circuit board in the control panel. The photo graph shows the circuit to drive one signal. This will need to be duplicated for each signal, plus I need to add the 'latch' that will turn the signal to green at the push of a button, but will automatically return it to red when the train passes over the 'track circuits'.
