Louis Marx O Gauge Accessory Lot Block Signal, Crossing Gate, Signal Circuit etc

Includes:
1) Bottom of an Automatic Signal Circuit Breaker, No Bulb, but tested to work using a bulb from the Block Signal.
2) Crossing Gate w/ Arm. Tested to Work.
3) Double Light Block Signal 454. Tested both Bulbs, Not sure how to hook up for full functional test, but seems to be getting power when I hook up a live transformer.
4) Crossing Track Section
5) Some sort of Straight Track for signaling operations.
6) 2 Single Wire Power Connectors
7) 2 Double Wire Power Connectors

These are Old. I can only check if the circuits are complete. Anything beyond that is the buyers responsibility to get fully functional. I do not know much about Marx products. I am an HO kinda guy.
