Continuing with the quarry load out signals, I have now added the black enamelled copper wire to the cathode (negative) side of the LEDs. The signals are a press fit into the building and the common red wires have all been soldered together and connected to a 5-point terminal block. The spider legs of black wire, in the picture below, will be connected to the remaining 4 terminals.
Also of note, in the top picture, is the improved concrete pier on the left, which the building stands on. The centre one has still to be done.
