After a few club-nights the main line wiring on one board is finally complete. The amount of wiring would have been a lot less if we had gone for DCC, but I am the only member of the group with DCC fitted stock, and it is not of the right era for the layout, so I lost that battle.
relays, controlled by Merg CBus modules, switch the various track
sections between the 4 main line controllers. There are only 3 points on
the main line on this board, controlled by the black Merg CBus
The wiring along the edge of the layout
consists the 4 controller feeds, 12V and 5V power supplies and the CBus
pair. The wiring down the other side of the raised section is the feed
from the relays to the track sections. The expanse of virgin white
board, where the documentation is laying, will be home to the MPD, and
will be covered with servos and more Merg CBus modules eventually.
