Got a bit carried away on the wiring side and ended up finishing it all off inside the shed
The twin track DC controller provides the 12v for the lighting (left hand knob), the 16v AC supply (straight off terminals on the back) and a DC track feed. The switch mounted on the black panel under the shelf selects the track feed from either the DC controller or the Multimaus wireless DCC jobbie.
The small black box at the bottom of the photo contains the diode matrix that is used to activate the ABC (automatic braking control) on the loco - it creates a slight assymetric voltage on the track which the decoder interprets and then takes a course of action, in my case thats stop, pause and reverse away. The switch on the box just shorts out the matrix, thus turning off the assymetric voltage and locos run as normal. It works a lot more effectively now the diodes are wired the right way round
With two of the same boxes at the station end (used to select stopping point dependant on whether the loco is pushing or pulling on arrival at the station) the Pannier spent about two hours today just shuttling up and down the line on its own accord - its a bit wierd coming out of the house and not seeing anything, then it just appears out from the shed and mooches down to the station before pausing and returning again
I need to have a play with braking distances, then the autocoach can come out to play and I'll see how / if it all hangs together as I hope.
As a last shot from me today, the buffer lamp (without its housing - I've got to find it now!) proving that LEDs are pretty robust, this one has been outside in all weathers for three years without any cover on it, lit up straightaway
