Being a real railroader and model railroader, I have to say, those couplers are he closest thing I have ever seen to the real thing. I model in HO and love Kadee couplers but I wish they would come up with a design like yours.
Woah!!! I love practical demonstrations, and this is why. :D This was amazing! Short, simple, straight to the point, and I could probably go change a knuckle on my local railroad now, as soon as I bulk up enough to lift 80 lbs into place while also manhandling the locking pins...
On 2nd watching, I'm paying closer attention to the mechanical loading and the bearing surfaces, and realizing that you're essentially putting hundreds of thousands of tons of weight on a bearing surface that's maybe a square foot in size (the little locking lip inside the knuckle that holds the knuckle closed). Now I'm wondering what part of the knuckle breaks most often...
@@c182SkylaneRG - there’s a video , coal train coupler broke and repaired . Gives an excellent view of where it broke . The area around the pin is really thin
@@jadenjacobs8667 You don't have to buy the whole printer. There are many custom printing services out there. Usually it costs per gram. And 3D printers are not really that expensive. My campus has one. Costs around maybe $350 (I live in Indonesia. I converted it to $)
That's a lot easier than in real life. I'd give you bonus points if you had miniature pin lifters. You didn't demonstrate how either knuckle does not a pin to stay "closed." However, one does need a pin when "opening" the knuckle otherwise the next joint won't make and the knuckle will likely fall out. I like this video; no yammering and no music.... a simple demonstration.
American RR couplers make so much more sense than those of Europe. Watching how the ground man in Europe must get between the cars to make the connenction gives me the willies. Railroading is dangerous, but the European coupling method seems to add to the peril.
There is nothing dangerous on the european version. Crew wait outside until bumpers are pressed together, then he just gets in between two braked cars and join them by chain coupler. But european railroads plan to change the chain coupler to DAC {Digital Automatic Coupler} by 2030s, because while not dangerous, there are still disadvantages like: 1. Need for extra workforce {Groundcrews} 2. Time needed to connect the cars {Connecting chain, pipes and cables separately, instead of everything at once} 3. Lower tonnage value before it breaks DAC V4: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5y1ESfnkXac.html
You can download the STEP file from the GRABCAD site by searching for the coupler entry. Having received several requests to make more but not having time, I made the file available to be able to make them independently.
I would have thought that the Europeans used these, and this says they do. en.wikipedia.org/wiki/Railway_coupling#Buckeye_/Janney_/MCB_/ARA_/AAR_/APTA_Couplers. That being said, I'll believe someone from Europe over some site in America.
@@michaelbujaki2462 well first off, do not ever use wikipedia as a source of information. the site can literally be edited by anyone from anywhere. second. yes some of the newer trains passenger trains are using something similar but different. 3rd img.fotocommunity.com/class-66-euro-cargo-rail-249f30c0-7d9a-4f84-9f9d-92fce82a6926.jpg?height=1080
@@michaelbujaki2462 they're only used in very specific scenarios like locomotive hauled narrow gauge trains in spain or some freighters in the uk, but overall the most popular couplers are the chains and buffer ones
@@benedekhalda-kiss9737 actually they do or they could not go around curves because the bumpers would push against each other. These are also more dangerous because someone has to stand in between the cars to connect and disconnect them which is why the is got rid of that system well over 100 years ago
Fun fact! If you remove the hinge pin while the knuckle is closed, you lose just about no structural integrity! All the force is held by the large pin in the back!
It's almost as if our species spent thousands of generations figuring out a way to communicate precise ideas by making sounds, and then somebody decided to ignore it.
H- type CBC coupling wow Small model I daily check CBC with measuring gauge 1 strage gauge 2 cantoor gauge 3 no go gange- shekle diameter Indian Railways
The chain or "3 link" couplers are a hangover from the early days of railways, they are only found on old freight stock here now. Most modern locomotives have "drophead" or "swinghead" knuckle couplers so they are compatible with old and new.
Great video! I was wondering how the retaining pin fitted into the knuckle. I've helped put the knuckle on a full size train at a museum, the thing was too heavy to do anything more than position it. If it was a tad lighter I would have taken a look!
So you have to undo both before the mechanism releases? Unlike in every movie where they’re on a train and just keep hitting one of them with a wrench...

This is a CBC Coupler System, which came to India with the German LHB Coaches I guess in 1999-2000, and has been used by many trains, including freighters. The Diesel and Electric locomotives in India are equipped with both traditional hook-couplers and CBC...
horribly complex with so many failure points. the japanese train coupler is so much better and simpler in design and its hinges are protected from the elements unlike this piece of garbage.
