Working Hump Yard

[FJ and G]

(not for your Horny engine)

Has anyone ever seen or heard of a working model RR hump yard, and if so, is there a web site. I spent yesterday afternoon surfing the entire web but came up empty handed. Surely there must!

I believe there was an article in MR a few years ago about a layout with a hump yard that had working retarders. I'm not sure what issue it was.

Fonda, etc.
Ed Ravenscroft had a working hump yard. I checked my copy of the issue. Among other things, he used air to retard the cars and used stepping switches that today would presumably be superseded by more modern electronics. The citation below was edited from the list that resulted when I did a keyword search on the Index of Magazines at this site, using "hump yard" as the search term.

Fully automatic hump yard, Model Railroader, November 1961, page 57,
( HUMP, "RAVENSCROFT, ED", YARD, MR )

I seem to recall another working model where they had solenoid operated retarders. It probably was cited in one of the other articles, possibly in Railroad Model Craftsman, but I didn't take the time to look for each article.
