PC Control Board (Part 1)

I figured it was about time to make a post to show that I've been working on things. What you see is the starting of the control board which will plug between the PC and the railway. The left hand circuit boards are the RPC modules which the computer talk to. The boards in the middle are CDUs (Capacitor Discharge Units) to operate the points. The paper on the right represents the TOTIs (Train on Track Indicators).

You'll notice the colour coding I'm using - the colour of the cable tie denotes what the function of the wires is (Point Control, Track Current etc) and the colour of the wire inside the bundle denotes what it does.
