And with today's multi-mile long trains, Distributed Power Units or DPU's are placed in the middle (or thereabouts) of the train to ease stresses on the couplers. If they break, the train goes into emergency and the crew spends the next few hours replacing the coupler.

[@jdgindustries2734]

The knuckle pin is JUST used as the rotational axis for the knuckle. It bares none of the weight of pulling the train and in fact once the coupler is closed and locked, the pin can be removed without any problem... Until the coupler is opened, at which point the ~80lbs knuckle heads for the ballast.

@@johnsworkshop3312 We just called it a "cut lever".

[@ryandavis7593]

Tight lock coupler type F . These are used on passenger locomotives and passenger cars. This one came off of a passenger car. I can tell because the cut lever is from the bottom and not from the top as it would be on a locomotive. Also I can tell it came from a passenger car because it has a vertical hole through the shank. Only locomotives and passenger cats are set up with this kind of draft gear. Freight cars have the draft gear pins inserted from the sides of the shank. There are a very few exceptions to this rule but that would be extremely unlikely to find along the tracks. Go to your local library and look for an article about and passenger train derailments in your area. This kind of coupler was used from the early forties to the present but you can narrow the search from say 1940 to about 1970. Good luck.. you may have found a bit of history.

Cool knuckle assembly! A very thorough job of explaining how coupler assembly functions (PLUS you cleaned it all up and made it function once again)! Great effort. Imagine being the lone engineer on a "dark and stromy night in the middle of nowhere" ...aaaaand carrying a replacement knuckle 40-50 car lengths to wear your knuckle broke. In your particular case, the entire "knuckle assembly" broke off. The engineer was dead in the water! Usually only the knuckle(coupler) portion of assembly breaks. Yes a "knuckle carrier" would have been quite helpful. Eack knuckle can weigh 85-90 lbs upto 110 lbs for a loco coupler. Type F and Type E knuckles. Your situation is unque.

Just imagine the tensile force on the very front coupler. Especially on freight trains. It’s basically holding on all the cars behind it!

[@johnsworkshop3312]

Yes - it is huge. I did some research and found that couplers need to be able to handle 350,000 pounds both in tension and compression. They proof test them to 700,000 pounds of force to ensure they do not break and are good at 350,000 pounds.

[@jaredkelly930]

Typically on a 135 car loaded coal train, the force in the first knuckle is approx. 440,000 pounds, when the slack is all stretched out. Or so they taught us.

[@Greatdome99]

Shear force as well. That pivot pin is all shear--no tension.

[@donaldswink6259]

All the couplers have a strength of 550,000 lbs. most trains run around 450,000 lbs because you have a rolling resistance of that. It’s steel wheels on steel track that makes it easy to roll.

[@RussReid]

Not to mention all the components working with the coupler, such as the the yoke, the vertical pin, the draft gear.

In England we had ( on the old slam door stock ) the BUCKEYE which worked on a similar principle. To open you had to reach down and pull a lever which opened the coupler so another can be attatched. You only needed one to be open to Couple Up. But it was also mounted on a loco screw coupling underneath so if buckeye fails, it can be raised to release holding pin, then lowered so loco pin is used instead. I only ever had one fail in service and at that time we were empty stock returning to depot. There was one occasion when a driver at our depot got laughed at, at every station he pulled into whilst driving a rush hour service. It turned out that a pigeon, disturbed on the track, flew up and got wedged in the buckeye coupler. It was released by using a hook-switch pole and flew away, much to every ones surprise.

I broke 1 or 2 of those couplers in my short time as a worker at a power plant in Northern Nevada. That plant had a hundred car coal train come every 30 hours with a load. In the winter, the hatches on the cars would freeze up and we would be sent to the trellis to “help” unload the train. I never worked outside and had no gear for the freezing weather. So there I was, with a heavy jacket, playtex kitchen gloves on a slippery steel trellis with it snowing and a train that would not vomit its treasure. Wham, wham we would hit the cars hoping the discharge gates would spring open and, yep, a few times they did. Then we would have the engineer accelerate the train and slam the brakes to jar the doors open. It worked for a few cars and suddenly the coupler broke. Yaahoo, break time at 3 in the morning.

[@jaswmclark]

What you are calling the "LOCK" we referred to as the "PIN" and what you call the pin as the hinge. Canadian railway terms. We used to say it was so quiet in the freight yards last night you could hear a pin drop (lock). Components are usually cast steel. Most common on line repair is to replace a broken knuckle. You will notice that the knuckle has keys top and bottom that match slots in the drawbar. Hence the coupler will remain closed even with the hinge missing. These were an improvement over the earlier Janney coupler and were developed by the "Buckeye Foundry" in Cleveland Ohio.

[@johnsworkshop3312]

Thanks James. That is very interesting about the hinge (pin) not being required once it is closed. A lot of engineering went into the design of these couplers that is not obvious to the casual observer. I wish the Buckeye Foundry were still in business - that would be a neat place to tour.

[@ICUNA22]

An interesting feature of automatic couplers like this one that is not generally known is that the coupler will work without a knuckle pin, when it is in the closed position. The knuckle pin is a pivot point only, and does not bear any draft forces that travel through the coupling. This is true for both "E" and "F" type knuckles. When knuckle pins break, many times all that is left is the very top part of the pin (if any is left at all), so this is a very hazardous condition when switching cars. If one is unaware that the pin is broken or missing, the knuckle can fall to the ground when the pin lifter is operated - a good reason to stand clear to the side when "pulling pins" in switching operations, or when opening knuckles.

[@johnsworkshop3312]

Yeah - it is super heavy - more than you would think just looking at it. I am definitely not strong enough to lift it up by myself. Mostly just pivot it around if I need to move it.

More components than I expected. Cheers from Sydney Australia

Very simple, very clever, very robust.

The design is indeed pretty amazing. Lots of thought went into it.

Interesting. And a great boat anchor.

Yeah, I just need the boat now!

[@DarkFlamage]

Try not to toss that in your boat while at the dock though or you might just sink it!

[@shaygetz52]

Summer of '76 my friend and I found one in a local river...just below the surface...we tried, oh we tried to get it out...just too heavy, pretty sure it's still there, too...forty five years later.

[@johnsworkshop3312]

Yeah, these things are super heavy. Hard for the casual passer by to grab one!

The tensile strength of couplers is unimaginable.

What I often wondered but never knew how to ask!

Glad I could help!

[@traceyl.cumberland225]

In addition to what I wrote earlier, you also did not leave the coupler in the electrolysis tank for long enough, it should be in there two to three WEEKS (not days). You could even leave it in much longer than that (example; the recovered civil war submarine has been in an electrolysis tank for over five years now and will be in there another several more years to come.)

[@johnsworkshop3312]

Wow - I had no idea. I found that my electrode got fouled pretty quickly, and I had to clean it often. But that may have been because I was using the wrong electrolyte. Maybe for those long times they have system to periodically clean it off.

[@TheSilverDartRacing]

Those were mostly used on tank cars, the side castings are to lock the couplers together to prevent them from coming apart in a derailment and slipping up and puncturing the tank next to it. . A potential for catastrophic results. Evan as you see the casting cracked and lost a piece it would still prevent a passed coupler.

[@johnsworkshop3312]

Wow - I can see that Type-F being much safer in a situation like that. Thanks.

[@Timinator2K10]

An ingenious invention...some unsung design engineer should be getting credit with his name attached to the coupler, i.e. a "Hadsen Coupler."

[@johnsworkshop3312]

Yeah, it would be nice to know who designed the type F.

[@tomconley2458]

More than likely the coupler was discarded prior to removing the tracks where your walking trail is. Our counties trail path used to be a train route.

[@thomasglynn2282]

I grew up in a mining town and we had a shit load of empty tracks, open pits, swimming holes, and logging trails. Back in the 70s every kid had an old motorcycle, and we would ride all day and never hit the same trail twice. Plus all the open fields for our junk cars we got running, mostly old vw Beatles.

[@johnsworkshop3312]

I agree, it was cast aside before the tracks were ripped up.

[@johnsworkshop3312]

Riding around like that sounds like every kids dream!

That quality of steel would make a hell of an anvil!!

[@bobcaygeon4533]

That was my exact thought too.

[@philliplopez8745]

If it were preworld war II ( pre atom bomb ) it would be worth even more as scrap

[@johnsworkshop3312]

I'm pretty sure this type of coupler was developed in 1954.

[@tcmtech7515]

Years ago I worked at a local rail yard fueling locomotives. Just out of the main yard area where the trains slowed down the most was a section of about half a mile that I picked up lots of pieces of those huge pins that the couplers pivoted on. Guessing that they would stress fatigue en route and that's where the tension was off them long enough for the broken pieces to wiggle their way out.

[@johnsworkshop3312]

Yes - that makes sense based on how these things work.

[@tcmtech7515]

@@johnsworkshop3312 Interestingly I found out that they could be machined into very tough hitch pins for the farm equipment. Where they broke in half was often the only part of them that was metal fatigued enough to matter.

[@FallNorth]

Much like the UK then, disused railway lines (and canal paths) become bike paths. There's one I use that has the odd bit of coal visible in the undergrowth.

I went to Grad School at SIU-E and lived near BAC. Cool video

[@johnsworkshop3312]

Cool. Our house is close to SIU-E. Great part of the country.

[@BossSpringsteen69]

Wow!. Now 30 something plus years ago i took home used tie plates from the CTA. I haven't graduated to this level yet. I've never disassembled a knuckle beyond the locking block,

[@johnsworkshop3312]

When I brought it home I had no idea what was inside it. It took a lot of research to figure it out, especially since all of those parts were essentially fused together in there. When I started I never thought I would be able to separate them. We seem to have lots of tie plates and rail pieces around here that were just shoved off to the side when the bike trails were put in.

[@Travelinmatt1976]

I've always wanted to find a coupler!

[@johnsworkshop3312]

Yeah - I cannot believe I found it out there after so many years. I figure it was probably left there in the 1960s or 1970s (still working to figure that out). So it would have been out there for maybe 50 years and nobody took it. Maybe because it was so heavy. It was only about 10 feet from the trail.

[@randysmitchell4810]

[@boneheadbonehead-sq3mt]

And here all along I have been tossing these things into to scrap metal bin when I replace them. Who knew they could be of value to someone!!

[@johnsworkshop3312]

I could see how they might be of little interest if you work with them all the time, but for someone like me on the "outside" it is fascinating to get to see a piece of the railroad up close and learn how it works.
