Can somebody please explain what they are, or point me in the right direction?  I see 'logging disconnects' for sale, but they look like regular or short-ish cars to me.

Thx in advance, sorry for the newb question.

First of all, Google is your friend. Disconnected log trucks is one possible keyword, which f. i. reveals this
Everything about the original can be found here in Seattle Car&Foundry Catalogue

They are dis-connected from themselves.

A log/s connects them.

They are a 'truck'..

Hence name.

Re Google.

Make sure there are no spelling mistakes or missing letters.

Thx Si and Helmut #1, got it. so an elaborate truck so to speak since they have some type of body built onto them to lash the logs to.

Helmut #1, yes I apologize if I wasted time but I probably would not have uncovered that Seattle Car and Foundry catalog!  Yes, did a google search and no catalog, lots of logging disconnects for the IT industry though.  :shocked:

adding 'cars' onto logging disconnects give somewhat better results and more IT related logging disconnects.

Thank you for the Catalog link - that is cool.  :bow:

Just imagine a small flat car with 4 wheels and a swiveling (or not) log bunk on top. Disconnects had couplers at both ends (most used link & pin couplers) so when empty a train of the little cars could be hauled to the cutting area. In later years, disconnects could be used under other cars-water cars, bunk cars, work cars, just about anything. Many times, the disconnects would be coupled together with "roosters" or long poles between them, especially when loaded. That made them a bit "safer". If you are interested in such things, there must be hundreds of books and magazine articles about logging and photos of various disconnected trucks. Loggers quit using them when the newer types of log cars became available, like skeleton and flat car type cars.
Wow...too much history, I could go on however.

Woodie,
nope - interesting actually. The thing about model railroading to me is realizing the actual human innovation and perseverance that went into these machines and operations at that time period in our history. It is absolutely amazing.

I run an engineering group and we have some pretty good tools at our disposal: Solidworks for drawings, of course electronic so revisions are easy to make, a PLM (Product Lifecycle Management) tool for tracking revisions, electronic rulers (micrometer) with digital readouts, pre-made electonic drawings of components we use, etc., etc. And we still have issues designing things. None of that stuff was available then of course. Just amazing.

Woodie tells me, he has a 1:35 scale-rule*.
He never uses it though.

Best design tool there ever was...
...is the ordinary human brain.

When working correctly...
...it has the astounding ability to invent simple & practical solutions.

I'm told the Egyptians used a water-level, for their pyramid foundations.
Simple.
Couldn't wait another few thousand years, for the laser-beam !

Hi Helmut,
To check out how they worked have a look at some Aussie disconnects in action see https://www.youtube.com/watch?v=HfdZFAjxiKM

Q - How do you know the new brakeman is any good?
A - He is still alive at crib break (lunch time).

John

You've just reassured me that 12.5% is OK for M.M.M !

The baked-potatos, wired to the brake-shoes...
...should be ready in time for lunch !

Dinners, Dead or Alive ?
Who knows !

Should have used precision carbon-fiber fan-cooled brake-shoes...
...with computer-controlled 'intelligent' ABS, of course !
Money no object !!

Or as my ol' workmate used to say...
...Object NO MONEY !

This is one of the drawbacks I have run across in planning a Southern Mississippi logging layout - no elevations higher than about 30 feet asl.

I will have bayous and gators, though. :)

Hi Rick,
No worries mate - Everyone can't have mountains. If you want Bayous and stuff can I recommend a quick look for the Muskrat Ramble layout for inspiration at http://www.freerails.com/view_post.php?post_id=25537 with video at https://www.youtube.com/watch?v=vPzvXXw0BEM
