Train Coupler Explained: Janney/CBC/AAR/Knuckle/Tightlock

If you have travelled a lot in trains then chances are that you have been in a train that used Janney Coupler. From Go trains in Canada, Class 313 - 323 in UK, Trains using CBC in India, and most of the freight trains, this coupler is used wordwide.

This videos specifically about the Janney Coupler (AAR/Knuckle/APT/CBC/etc). After some researching I have consolidated some interesting facts about this coupler, so I hope you enjoy the video.

Thank you good teacher! You and many YouTube videos explain it well. There are so many questions, and each of your videos contribute to a full understanding.

Great explanation, thanks for your great service

Very informative, exactly what I was looking for! I'm planning to run a TRPG session which will be taking place on a train and wanted to understand this mechanism in case the players decide to mess with the couplers 😂

[mattiasthorslundjonsson]

Using Janney couplers together with buffers looks a bit special, compared to North America (Janney/AAR only) or Europe (buffers but a simpler hook and loop coupler). I take it that the buffers must be pressed together slightly before the couplers will lock? But it makes sense to keep the buffers after a coupler conversion.

By the way, I believe Type F, the improved coupler used for freight cars, is designed to prevent cars from decoupling and turning over during a derailment. If a car starts to topple, the neigboring cars will resist this, as the coupler is designed to prevent that type of rotation. And avoiding decoupling is a defense against telescoping of cars during an accident. The passenger type coupler has this safety feature, but also comes with sprung drawbars (i.e. the connection between car and coupler), which provides better comfort for the passengers. But the buffers, if present, provide more or less the same comfort, i.e. reduced jolting due to "slack action".

For passenger trains this is combined with a Pullman gangway with the faceplates being in compression. The friction between adjacent faceplates provides damping. After a while these faceplates become highly polished. This feature is important for achieving good ride quality.

Wow, that's a good explanation 😍

Knuckles. The superior couplers! Why the rest of the world does not recognize their greatness I will never know.

Most important thing is the Trains. Libality❤❤

[truthsayers]

ive wondered this for many years (my dad worked for a class 1 railroad in the US for 42 years but no longer remembers) HOW do the couplers, with the pin on the bottom work? you show them at 6:15. the pin cant 'drop' to make the connection because gravity would pull them down and disengage the knuckle. there must be some complicated linkage to LIFT the pin and hold it up in engagement

[delurkor]

I assume the last shots are of Indian or Pakistan railway, they use both Janney style and train buffers. Very interesting combination.
And thank you for the video.

Dont call it a Janney coupler, the Janney coupler is the first patent for a knuckle and it was different because it had a rotary pin instead of a lifting pin, it also worked wayyyy worse

[louisrobitaille]

0:49 Wouldn't it have been be much safer to just add a small ladder to each car so that the guy could just hold onto it and move with the car "rammed into" instead of having to move by himself? Or even better, have the guy starting outside, then move in-between when the two cars are together? 🧐

[thiswasnoboakingaccident]

0:47 That was a stunt. ..right? I thought for sure a man was about to get killed.
That can't be SOP can it?

[wellingtonnorthjunction]

They are called buckeyes the fact you don show the British saying of it when the British invented trains makes me think England doesn’t exist

[johnnyboboquinn]

need somebody whos less ethnic to explain such an iconic component
