I remember seeing this picture in MR a long time ago. The Union Pacific built a model of their hump yard in Hinkle Oregon as a training layout. lol
1977 press photo harry meyen of union pacific demonstrates hinkle yard model. this is an original press photo. Union pacific executive herry meyen demonstrates model of new hinkle classification yard in easter oregon.
Model, which will be used to train 300 to 400 hinkle employees, is mounted in rail car.

Gotta love that suit. Looks like they recycled an old sofa.

WHAT IS HE HOLDING UP? LOOKS AS IF SOMETHING IS OVER THE CENTER TRACKS.
I think that may be the watermark that you're seeing.
The Shelby(Oh) HO Scale club has or had a working hump yard with air operated retarders.
Here's one on You Tube.

I think it's an N scale boxcar his is setting on the hump.

Speaking of N Scale..Here's a hump yard.

Not really. There's no hump. And no retarders. The whole thing is on a slope and cars just slam full-speed into the ones already in the body tracks -- check out the impact on the last two cars.
There are some people who build poorly-working model subsets of hump yard functions and call it a "hump yard."
There have been only a handful of truly functional model hump yards built with working retarders that can actually handle one car at a time and control the speed with which the individual cars roll into the body tracks.
99% of the time, claimed true "hump yards" in HO or N scales -- aren't.
[Edit: OK, maybe "99%" is a little high -- but not by much.]

Here's a web page with more of the storyhttps://www.up.com/aboutup/history/stories/construction/construction-hinkle-hump-yard-anderson/index.htm
The same model was later rebuilt to be used for training on one of the North Platte hump yards.
By the way, I don't see anything like retarders here, either, so probably they couldn't hump individual cars, but instead demonstrated how the various yards would work together.

Correct and the Shelby club has/had one that worked quite well with air retarders just below the crest of the hump.The cars was controled to a easy coupling. A computerized air system would probably be superior to a manual operated hump.
As far as the others who am I to judge what a builder calls a hump after all a hump is a man made mound.
Here's a sweet operation found at lake and tide water docks and as we know its not a hump.

I'd really like to know how the air retarders were constructed.

The retarders was made from brass tubing and had control knobs along the facia. Controlled air flow slowed the cars progress down the hump and into the bowl.
As I remember, if the air was turned up to high, the car could be blown back up the hump.

True and the cars could be stopped if there was a need.. It was a joy watching cars being hump..
I have an operating hump yard on my N scale layout. The crest of the hump is 1 3/8 inches high. There are ten classification trcks, broken down into two groups of five by a wye switch at the bottom of the hump. The two longest tracks are ten feet each. Works quite well.
I had a yard which I thought of as a hump yard because it worked on gravity but it wasn’t an accurate model of a real hump yard, just a place where the yard was at the bottom of a grade. What it was, was a time saving idea because like a real hump yard the switcher doesn’t have to move every car and constantly go back and forth.
