Working HO Couplers (split-off thread from "Quick Answers for DCC Decoders")

Hello Railfans! Welcome to the new thread concerning “Working HO Couplers”.

NOTE - For those of you already familiar with this project and want to skip the intro, please skip down to " ALL COUGHT UP! ".

For those that are new, please read on

This thread originally started in the “General Discussion” section of the forum.

Being that it somewhat revolved around some DCC particulars, the MR staff moved the thread to the “Electronics and DCC” section of the forum.

After many posts, and the answer been found to the original post, the subject drifted off onto the reason for needing DCC answers in the first place… to control a working set of couplers.

So where are we today? We have the couplers, but no DCC to control them. In its place, a magic wand. To further bring you up to speed, here is a list of video links (in order of production) marking each step in the coupler process.

  1. This video shows the first two test cars (boxcars) being tested. https://www.youtube.com/watch?v=nkQjlLqgATs

  2. Ofcourse, what is a good project without some sinicism? To wit - one of our galant readers was curious as to how the ‘flatcar’ version would be made. That led to - https://www.youtube.com/watch?v=uV5yKGxATw4

  3. With two types now working, lets try them together. https://www.youtube.com/watch?v=mv36TN2P9wA

  4. After some deliberation amongst the thread readers and myself, the best version of the design finally arrived. Simple ‘over the roof’ activated uncoupling. https://www.youtube.com

Here are 3 more video links.

Two videos i didnt have time to post earlier. Coupler work makes you sleepy…

And a link I forgot to put in the opening post…

This link takes you to a page where you can select which individual coupler video you want to see instead of wading through the links above searching.

As you will notice in the two former videos above, it IS INDEED POSSIBLE to uncouple Kadees from each other by only activating one.

This beyond a shadow changes the belief that two couplers would be needed for uncoupling. However, by reducing the amount of mechanical action of the uncoupling process, your rate of success for each uncoupling drops.

Slack now re-enters the equation of uncoupling cars. You operational hounds should love the implications of this!

While the Gen II has demonstrated it can actually open the face far enough to slide past the opposing face, the ‘fingertips’ will grab depending on your slack. Whereas before, with both activated, this wasnt a problem except in extreme stressed situations.

Can one coupler be activated only and uncouple the cars? YES.

But at a slightly less success rate. The fix? Radio the engineer to ‘jostle’ the slack out of the couplers. Try to pull the pin again. Just like the real thing!

More to come - Stay Tuned!
