Good Evening,
I haven't done much with the Ginny since last time - the body has been sprayed in Red undercoat and it is a very nice finish for Halfords spray paint - I will be using their Carmine Red colour for the bodywork for the topcoat.
State of play at the moment, I think I am going to paint the underframe tomorrow in the absence of anything better to do currently. I have a nice tin of Black paint which is similar to blackboard paint that I think will provide a good finish for the underframe.
The only real interesting piece of news is since my layout has been converted to DCC I have decided to take the brave step of converting this shuttle car to DCC and install lighting in it. I've drawn up a wiring diagram based on what I think is the requirements I will be needing - there is only one alteration I might make which I shall explain in a moment. I have drawn up a lighting diagrame for the project:
As we know the Acton Shuttle is made up of G23 Driving motors that have been modified for single working. The original end, with the most shutters like the link below:

Is what I am classing as my 'D' end and technically will be the back of the train - is will be because the motor is technically sitting the wrong way round in the motor bogie frame (as the instructions rightly say) So the rebuilt end will be the 'Front or A' end because it is sitting over the motor bogie.
The wiring diagram - provided I have drawn it right, will have the directionally correct head & tail lights working off of the F0 key, additionally the cab light will illuminate at the end with the head light lit as well, and the tail light lit at the opposite end. On the model only the two left-hand most light shutters are depicted as 'open' so both ends will have the Head & Tail light combination as shown above, with the tail light above the headlight - I might change it over on the other end with the tail light in the bottom corner I haven't decided yet, more research is required before I place any LEDs in place- I have also been considering a bi-polar LED at the D End which has the ability to show either red or white dependant on direction of travel so I might model the D end with two white lights one doubling as the tail light while the A End will only be red and white singly dependant on the direction of travel - might be interesting.
Now if I have understood the DCC wiring correctly when I drew this up the Passenger Saloon will also have interior lights linked to the F1 key on the decoder allowing me to run the train 'in-service' with saloon lights or 'ECS' with the saloon lights off but still showing head & tail lights. For the passenger saloon I have been considering the use of a commercial LED Light bar to simplify matters rather then individual LED's wired in Series or Parallel as show in the above diagramme - this is why the Green wire simply links to Coach Interior lighting rather then specifics.
All LED's are planned to be the 'Warm White' colour to simulate the use of conventional incandescent Tungsten bulbs used throughout LT at that time. As a interesting fact in the prototype the bulbs were wired with six bulbs in series as a 'set' and between six or eight sets per coach - so if one bulb blew it would knock out six at a time until it was replaced.
I hope this has been interesting, and now its time for me to get the soldering Iron out and warm whilst I order the specifics needed to install lighting. Now where am I going to install that decoder...
