It’s official…the wiring for the first lower staging yard board is finished!

The underside of the first lower staging board, showing all the wiring needed for the block detection, track buses (one for each of the two yards) and the accessory decoders
The black/red is the main power into the board, feeding the PSX-2 circuit breaker, which splits it into two separate buses for each yard. The blue/brown is the 12V accessory bus for the accessory decoders running the switch machines, and the green is the ground/common direct from the command station for the ground connectors on the BDL168 block detectors. The grey cable is the LocoNet cable
The yellow wires/connectors are the block detector feeds for the Metra yard tracks on the second board, the orange wires/connectors are for the Freight yard tracks on the second board
