Signalling Success

I've finished the electronics for the 4 signals at the east end of the station.  To my surprise there were only 2 mistakes (after I realised I'd plugged one of the connectors in backwards!).  Current consumption is up and my 12V 500mA PSU can't cope any more (the IR LEDs take a big chunk each, plus numerous red and green LEDs at 10mA each) so a 2.5A PSU is on order.

At this stage it is only the mimic signals on the control panel that work.  Fitting the actual signals should now be a relatively easy task of running the control wires back to the control panel (the wiring in the control panel is already complete).

The signals work exactly as in planned:

1. The correct route is selected (i.e. set the points)
2. Press the 'Eastbound Departure' button
3. The signal for the selected route changes from red to green
4. As the train departs and activates the track circuit in the tunnel, the signal automatically changes back to red

I've now removed the control panel and taken it back to work where I'll build up the circuit for the west end of the station.  I'm also pondering having an automatic signal outside the tunnel on the eastbound approach.  This will, probably, be automatic.

The top right section is for the west bound departures - the sockets are fitted, but no wiring yet.

The colours on the photo aren't great - but you can just make out the mimic signal  in platform  3 is 'pulled off'
