Part of the process in upgrading Brettell Road and preparing it for part 2 was to redo the wiring. Those that have been following from the start will recall that it was initially only a plaything and not an exhibition layout and the wiring reflected that being just 4 wired between boards. 2 for the DCC and 2 for the AC supply.  A concession was made after the first show to provide short protection for each board but its not really how things should be done so its been mostly stripped out and done again.

So now the DCC is split into 3 sections. One for the yard, one for the mainlines and one for the accessories. Theres little point having short protection if said short cuts off the ability to throw the points and resolve it. The AC is also split into 2 sections as well, the second being a DC supply for LEDs. You can use AC for LEDs anyway but the flicker can be noticeable sometimes.   So now theres 10 wires between boards instead.


The new arrangement for entering the yard has required a few new signals as well. Mainly a couple of ground signals from the MSE kits. I need a couple more for part 2 (one of which is a double) so I built them all together.  these are powered by servos controlled by a Tam Valley control board.  I guess this also comes under signals? A simple limit of shunt sign from a MSE lamp a bit of brass tube and some microstrip.
