All the wires are hidden away and everything is working ok. "The lights are on but nobodys home." Well, the dumper clamp-springs are not strong enough to hold the car upside down against gravity, so am design-building a hold down clamp for the cars as they exit the dumper. Tested by holding the dumped car with my hand and that works... the couplers stay coupled and the car gets back on the track.

Note the servo and yellow wire to the right of the dumper :) It works. This makes 6 servos used to unload a coal train.1. positioner wheel mover
2. positioner arm grabber
3. car gate arm stopper
4. car brake axle grabber
5. rotary dumper rotation
6. exit wire hold-down
One of the buttons on the BN control box is no longer connected to the controller.. the resistor wire is snipped and the pin is used for the exit servo. The wiring on the hard wired controller has become embarrassingly atrocious. hmm, spellcheck does not like the word positioner, o well, it can be found on the web.
