This 9 minute video features a CSX unit train with bathtub hoppers, rotary couplers, an operating flood loader and dumper, and Appalachian scenery. More info in the credits.

The rotary couplers and draw bars are the sketchy part of this setup; with 23 cars I get a derail or two when pushing out of the dumper. Couplers are hacked from old Rapido trucks and Fox Valley knuckle couplers, but most of the cars are connected by fishing swivel draw bars installed in MTL trucks.
The flood loader is driven by a Tortoise and controlled by a toggle switch.
The dumper was inspired by a video with footage of a Detroit Edison power plant that dumped 100-car trains in two hours. The one on the layout continuously cycles and just has an on-off switch. One DC motor spins the dumper drum and a second drives the ram. The cycle is driven by SPDT switches, diodes that control voltage direction, and a +/-/common power supply. Direction to both motors is controlled by a switch that is thrown when the ram arm is all the way up, pushed there by the drum. Limit switches turn the motors on and off.
The odd structure next to the dumper building is a dust collector modeled after those sold by Aircure: www.aircure.com/
