Having only seen a demonstaration of this at an open day in the UK, I was pleased to see this happening on the main line in the US. The defective weld had been marked, once the P-way team arrived there was one last train before the repair began, the defective weld was cut out quickly leaving a 2 to 3 inch gap, the ends where then aligned and the mould fitted. As soon as the track ends were pre-heated the Thermite was ignited and the gap filled. There was then much cutting, bashing and grinding before the joint was finished. The next train passed over the weld within two hours of the previous train.

I was the lead Welder in Phoenix from 96 to 02 and went to train service.
It was the best railroad move I've ever made.
I was on the thermite welding gang with Canadian national railways, had the best Foreman ever, happy retirement Dave McPherson you where the best!! You treated us like gold, I hope you're doing well,
I was a ship yard welder many, many years ago. Watching this thermite welding technique just blows my mind. I doubt it could be used on the hardened armor plate on many parts of the ship but it is very cool (or hot) to watch. My son works for BNSF and started out as a welder for them. We talked about his work and I never could grasp what he was doing it was so different from what I did on US Navy ships in the ship yard. Thanks for sharing this. I just gotta talk to the kid about all this.
RQ100A or T-1 would be done the same way
Look at the final weld...very clean. These guys take pride in their work obviously.
They did a good one for the video. The rest were shit.
Hi! Here we have men who are working hard and they have a lot of stuff to work with but nonetheless they are doing very well with their job! My job is close to train tracks so I hear a train now and then!
I find this strangely satisfying to watch.
As an adult I'd say,interesting but as a "Rail Fan" I have to say I,Love it,love it,love it!
I don't know what is the use for watching this video but I love to know things of which most of people does not want to know. Thanks for sharing.
Interesting And Educational Great Video.
Thanks for posting.
Show o trabalho, muito bonito! Parabéns à todos!!!
What's the reason for the hydraulic jacking of the left overs? I'd have thought it might have cut the metal off the top of the rail but looks like it just pinches it together.
A job well done to them.
seen it done many times over here in England, interesting to see stateside that the trimmer and grinder and hydraulically powered, also that your leg shields have a sheet of metal on them ours are just canvas... if you even get any

YOU CAN HAVE WHATEVER YOU BUY FOR LEG SHIELDS.
Hey at least over in the UK y'all got concrete rail ties. Over here in the US we still have creosote treated wooden sleepers on a lot of spurs.. even on some main lines 🤦🏻♂️
Wooden sleepers handle heavy freight trains better in most instances and thats why they are so prevelant in the U.S.. Even uk freights are light in comparison.
@@dustinvarner3438- Concrete and steel ties are more durable but also more expensive in most regions. Some railroads use steel ties.
As wood ties can last a half century they remain popular.
anybody know what type of firecracker he throws in the pot ? i'm thinking Termite.
After grinding , nobody bothered to check the profile of the running edge ?
The grinder is very skilled and experienced.
good job men!
What's your Heat Index at?
These boys mean business!
I love TH-cam. Where else can you see this kind of stuff?
Thanks for sharing!
The top of the break out sledge could have a bronze cap--to prevent denting on a missed strike.

You fill-out your Fire Risk Assessment Book?
what kind of steel is left over from the weld;;;thank you;;ger [IRELAND]
Gerardo: Same as the parent metal.
Thermite welding process observed in a steel plant in India which is situated in bhadravathi the plant is great maharaja of Mysore and sir M visweswaraya the application for overhead EOT CRANES TRACK line RAILS.
ive been working on the rail road
I've never seen that. My first reaction was how cost-effetive is that?? Seems mighty labor intensive vs the old way of just arc welding (?) a joint
It's pretty quick compared to how long it would take to completely arc weld a 1" wide gap and reliably forms a very strong joint.
Simon Ross typical union response
@@simonross6015- Thermite welding makes a joint that if done properly is about 60% as strong as the rail.
Rail is not welded together with electric stick welding. It is done by sawing a short piece, ½”-1”, from each rail end to make a clean, rustfree square butt end, very slightly angled up. The rail ends are clamped by the butt welding machine, pressed together with many tons force. Then electricity is passed through the butted-together rail ends. The rail ends are pulled apart a little, drawing an electric arc. When the rail ends are heated to the correct temperature, the current is turned off. The machine squeezes the rail ends together hard enough to make the steel bulge out. Then the joint is quenched. When done correctly the joint is about 90% as strong as the rails. The rail top and the flanks of the rail are ground smooth and the flash on the sides of the weld trimmed just as in Thermite welding.
This process is used in rail welding plants in railway shops. In the field it requires a special electric welding machine with a diesel powered generator. Videos are on TH-cam showing this.
these guys are way more efficient than the guys in the Sweden video
50 guys in India to do the same job 20 guys in another country i watched only 3 guys in USA, A LOT NEATER JOB TOO. Quality is a stand out.
Really interesting. May be safer than it looks, but I'd want at least a grinding shield and long welder gloves.
Good grief, the tools our US boys are using are way more worn and simple than the tools being used in Sweden and Australia. Was surprised to see them placing the hard metal billet into the preheated chamber "by hand" instead of using hand tools and a guide. Experience counts.
YEA ASS WIPE IT WORKS
*"Good grief, the tools our US boys are using are way more worn and simple "*
1) "worn" = "productive." Sign they're actually out working, not sitting on their duffs.
2) Ever heard of the "KISS Principle?" The simplest solution, that actually works, is most likely the best.
I’ve always said there are a 1000 ways to do the same thing or a 1000 ways to get to the same place... end results are what counts
how about aneeling like a bandsaw blade but on a larger scale
Was this in Ashland, Va?
In the background you can see the post office in Folkston, GA. Can find this view in google maps.
I live about 100 miles from Folkston. When I saw it in the background I automatically thought, "That looks like south GA".
The old fashioned and cumbersome way! Hurray USA!
Are those sleeper are wooden??
Yes they are
Good to see the 1800s technology of wooden ties still being used here.
Wood is still the best. Concrete cracks and is expensive, composite is way too expensive ! After all the New Democrats want a welfare state so you have to cut corners on some things. Asking a Bum to go to work and contribute to society would be too harsh, so we cut important things like railroad engineering and maintenance of bridges, can't cut a food stamp, God forbid !
If it ain't broke....
Richard Wielgosz Wooden ties are still used in North America (Canada, U.S., Mexico) for freight services, however concrete ties are used on high-speed passenger lines. Wooden ties, unlike concrete ties, don't need replacing every 5 years, as well as wooden ties being cheaper to replace every 20-30 years. Although some railroads will neglect this and never replace their rails whether they be concrete or wood. Which unfortunately leads to derailments, in some cases railroads claiming the cause to be "a fractured" or "a broken" rail.
+Litch Wolfgang Concrete sleepers don't need changing every 5 years. If they need changing that frequently something's badly wrong. All other factors being equal, concrete sleepers should significantly outlast normal softwood sleepers even when the latter are treated with preservatives.
+Simon Ross probly in areas its very cold ice can cause it to crack
This is a super slow process but nice to watch
Me gustaria hacer ese trabajo de rielero siempre hay que aprender hacer algo mas muy educacional el video gracias
GIT R DONE
b3j8 to answer your question this process has been around in some shape or fashion since 1908 i believe
The reply button exists
The two ties under the weld need to be replaced and a good amount of rock tamped under those ties , to support the weld .

With the Railroad you need a Union.
I've got over 29 years with the Railroad and I wouldn't step foot on property without it.
Seen a weld done in 20 mins train used track in 22 mins not recomended , Ive also seen other things I cant write about here :)
Things have surely changed since they headed west in the mid 1800s
Thermite welding.
Wonder what the old boys who worked on turn-of-the-century(20th) track gangs would say watching all this! LOL
They would think that they are on vacation, lol.
Would have been more informative IF there was an audio narrative to explain what is happening at each step along the process of the realignment and welding. Just a thought.
I can not imagine doing this at every joint in the track, like the track between New York and Washington DC. The number of joints is mind boggling for that track.
@@3superpar- Field welding is used to weld ¼-½ mile or longer rails that were electric butt welded in the rail welding plant at a railroad yard.

Why are they still using wooden sleepers
Concrete cracks, steel shorts out track circuits, and composite is expensive. When you have thousands of miles of track it gets very uneconomical.
Concrete is used on high speed main lines like the Northeast corridor, but with tens of thousands of miles of track , wood is still the best tie material for rails.
India being a poor country compared to US has concrete sleepers all along its railway network.
+Herthan That's why there should be plastic seating pads and inserts on the rail clips to ensure the rails remain properly insulated from each other.
+PrithvisAccount Concrete sleepers in India? IMO that is very likely due to political "graft" than any actual engineered reason. India has its fair share of very capable engineers, and concrete is not a viable solution for sleepers.
3:50 Mr. Clean
Wow i saw the Indians doing this in rubber flip flops and i thought it was crude only to see americans are still doing it the same way with the same technology !
What new technology do you know about that the railway companies haven't heard of? ?
Portable electric welding equipment is used but is much more expensive and cumbersome.
However, they are complicated, there is not so much remachining in Europe
hey guys i m an Master Welder from Germany, is it possible to come to the USA and Work there as welder ?? can someone Help me pls
Pretty sure you'd be more than able to come over here and find employment. You'd just need to get your work visa or apply for citizenship... I'm not sure how much of a pain in the ass that process is though.
Dude turn off your caps
idiot
Best of luck to you!
Why wooden ties, why concrete ties? For all the lack of real information I see on here other than pre-conceived notions of what is better - each have their place. Concrete ties can not handle the weight of the wood ones without fracture. Wood allows for much better flexibility. Here in the U.S, The cars are longer and weight more. If you watch a video of a train crossing an intersection here in the us, it's not uncommon to see the track 'flex' down a couple inches under the weight. The concrete crossings fail extremely rapidly and have to be rebuilt consistently here - largely due to this flex as well as weather (Most tracks in US are in areas that see high freeze/thaw conditions. Wood is much better adept at handing these cycles and maintaining integrity. Concrete has a tendency to fracture and within a few years, fail completely - It's not unheard of here to have wood ties in place for 50-75 years depending on the traffic. The high speed corridors here are a different matter and are generally concrete - but the maintenance is MUCH high on those than on freight tracks. It's about both economics and ability to perform maintenance. Too many are saying one or the other - sorry the world isn't black and white, but there is an application for everything. Plus, remember that Europe has twice the people as the US has to spread this cost around, while cars are more popular in the US - leaving much less train funding available for public transportation. (BTW, This is much the same reason we still use mostly wood in our houses vs. steel - Just handles better through environmental issues - and we all know we have issues here in the U.S. (Pun intended))
i just saw some other video where like six guy we're watching two guys work same shits going on here to
nice the railroads in USA are not begging the congress for help :)
granskare no need they just steal the money they need from Wall Street
You hold the hammer at the ready and I’ll hold the spike and when I nod my head you hit it.........
Thermite - for when you need molten steel right the hell NOW - and WHERE you want it!
glad your saying that. I ve been arguing with hillbilly know all who says it won't put steel only iron. and that they don't thermite weld track any more only stick weld it
+tommyfree4736
THE PROCESS YOU JUST WATCHED IS THE NEWEST ONE AS WELL. IT DOESNT REQUIRE THE TRACK TO BE POST TREATED TO PROPER HARDNESS. IT DOES IT ALL IN ONE STEP. ITS PRETTY COOL. LOOK UP HIGH PERFORMANCE RAIL WELDING.
Steel foundry in a can.
Yep. Just ask the Architects & Engineers for 9/11 Truth
Thermite is used to attach steel, not cut it. The terrorists did not weld the towers down.
My dad and I seened some termites at Taco Bell and they gived us free food
Can't have bad backs or knees for this job............
That's why you don't see a lot of old men doing it. They have already worn out theirs. The most valued tool I have in my box now is a set of knee pads. Wish I had the brains, guts, whatever to wear them when I was in my 20's.
Interesting video. Thanks. Face protection and lower leg protection, fine, but no ear protection, bad. They'll all go deaf in old age. Question: what happens to the molten aluminum in the thermite? It doesn't contaminate the weld?
The aluminum is the fuel. It is all burned.
Ol
Blue jeans?
It seems to me that a large electric welder could do the same job in half the time.
You can expect a thermite welding team to be able to get a weld like this done in about 30 minutes from start to finish, I doubt arc welding a 1"/25mm gap could be done in that time never mind half of it and reliably pass inspection and ultrasonic testing anywhere near as well.
Simon Ross Just shows that I know next to nothing about tracks snd welding. Thanks for the information.
No problem at all :)
The guy in the orange hard hat is a supervisor. Apparently they don't have to get dirty...that's below their pay grade. Typical of any union job.
+ROTAXD Most Union shops don't allow Supervisors to do any hands-on work. Their viewpoint is: "If a supervisor can do it, then that means that they can hire another hourly person to do it." He probably technically did more than he was evennallowed to
ROTAXD supervisor's generally aren't union members and a good union guy wouldn't allow a supervisor to do hourly work
nick longstaffe good union guy roflmfao. Every union guy I've ever worked with in my adult life is lazy.
How bout the ones that fought for equal rights and equal pay or the ones that fought for safe work conditions and an 8hr work day,
Lib Smiter that statement is terrifyingly true, there is still a need for union environments in lots of situations, if not the very existence of them raises the standards for unorganized workers,
One good example of where unions should be implemented is for servers and waitresses, as strange as it sounds it's legal to pay them less than minimum wage because they are supplemented with tips, how is that even allowed? A little organization goes a long way
Hahahahahaha the us still mounts tracks in wood
I cant believe there using thermite there are better welding procedures.
+D Fuller NO THERE ARENT. THIS IS THE STATE OF THE ART PROCESS. NOTE THE PLUG DROPPED IN JUST BEFORE THEY TAP THE THERMITE CAULDRON. THAT SETS THE TOP OF THE RAIL TO THE CORRECT HARDNESS. NOT POST TREATING REQUIRED. IT,S A SHAME YOU ARE AN IDIOT OR YOU MIGHT KNOW THESE THINGS.
good olde Yankee ingenuity ... like an on-site steel forge
+Kevin Olesik I think that the technique was developed in the UK. Welded rail was used in Europe for a long time because of high speed passenger service.
Countless trillions of tons of good cement making sand available and we still use wood ties????
+JetMechMA The sleepers are sitting on ballast which should be compacted and will complete negate any shock absorption and in any case on concretes the rails sit on rubber pads, if there's any voiding the entire track dips regardless of whether concretes or woods are used. In the UK and Europe at least concretes are being used to replace wooden sleepers in the vast majority of new installations and renewals because they last far, far longer, typically around 5-10 years for woods, up to about 50 for concretes.
+Red Woods There are plastic ties being made from recycled plastic waste. Those do not rot and will last much longer than wooden ties. They will likely be used more in the future.
+John Ferguson
In the west, anything but concrete ties will burn....and they do. Europe and Asia are using pre-fab sections of pre-assembled rails and concrete ties laid on ballast with large machines which may carry 10 flatcars with 100 sections automatically shuttled forward to lay track FOR the entire machine. THAT is efficiency!
Prefabricated panels are how new installations and renewals are often handled in the west too, I have personally seen the track laying machine in use on London Underground, it's great for long, straight sections. No good for points and crossing layouts and less useful for going through areas of limited clearances like platforms and tunnels though.
+Simon Ross
Understandable.
No confidence in there welding both guys holding a hammer to stop weld pouring out
kind of time consuming
They messed up the spacing on the wooden ties (see 9:58 onward), reducing support for the weld on one side.
to all the foreigners,
1.the guy in the orange is a supervisor whitch means he's there to watch the guys with the white caps because there rookies make sure there not messing around
2. they have all day to do one weld there not in in a hurry there's different ways they do this if there's many to get it done faster
3. we're not all fat just tend to be in the city because everything is given to them by farmers like me. I am definitely not fat either
4. I'm pretty sure 3 goes for the same in Europe
So many things done improperly... many safety violations... ballsy doing this on camera without the proper ppe on... this video will get you sent home at csx...
Thermite ...corporations must be above the law
People are so full of chit
Alumino thermite: perfect for welding rails. Nanothermite: perfect for heat blasting the twin towers construction beams.
Yes, the sad Truth.
So many people, who have no building or Material understanding.
Believing that 3 buildings, 2 of them made out a an external Skeleton.
Comprised of 6" thick A-36 steel.

It would be a nice use for recycled materials instead of wood for those ties....No?
Dont know. Dont care. Ask Mike Rowe if this works for most everyday people. Stop advertising to average people.
this guys broke all kinds of rules doing this, too close to the weld, mud sticks, hiting the rail, torch too cold, acident waiting to happen. by the way i do this for a living.
too bad you can't spell correctly.
mojocruz1, I hope you are not the one in charge.
Does to molten metal flow out the sides and then into sprue holes or does it flow out from directly in the center
I hate to say but the previous video with the Swedes made the US guys look like hobo's. And the Swedes don't have a third guy with his finger in his ass. They got it done, but I hope others here do better. And the wooden ties are best - Europe cut all it's wood down 300 years ago. Wood gives, cement breaks. And walking the tracks when I was a kid pulling out all the date nails [incredible - copper nails were driven into each tie to show install date] most of them were in the 1930's - and this was 1970! Still had life in them at 40 years old. Here in California you sometimes find Redwood and Sequoia ties from the logging railroads in the mountains. They are untreated and date from the late 1800's - still good for landscaping, or re-sawing into furniture wood.
Unions. But I bet the one that's not doing much is foreman/supervisor, rail safety inspection or doing some kind of audit. Notice his pants are very clean compared to the other two, but he knew what to grab and when. Maybe he's a trainee.
Concrete sleepers have a much longer life expectancy than wooden ones all other factors being equal which is why they're being used to replace wooden ones throughout Europe, it's not down to a lack of wood.
Keep in mind that we have tens of thousands of miles of track. We can't afford to be sophisticated like Swedes.
Richard Raucina the guy in the orange hat is a supervisor the guys in the white hats are most likely rookies that need supervision until a certain amount of time has gone by were all about safety here
Florida East Coast Ry pioneered concrete rail ties and swears by them. They run heavy unit rock trains as well as their hot intermodal traffic over them; soon they will be running their own passenger trains over them. The concrete ties have rebar inside for stability. They ride harder, yes, but I'd rather have those under a train than the rotten trees I've seen on CSX track. A friend pulled out 5 consecutive spikes quite easily with 2 fingers from a CSX mainline, that's how bad they let their ties get. No thank you!
Thermite....sounds familiar....*farts*
El método Europeo es mejor!!! Eurpe way are better!!
Feminist, please apply for this job.
American work safety standards? - (a) look at the dipstick wearing no gloves throughout including the hot work; (b) the guy doing the grinding only wearing leggings for that (cos levis are fire proof during the thermit bit, right?). (c) All wearing short sleeves; (d) Guy on the hammer without ear defenders (e) and his mate (Mr no-gloves) head 2 feet from the hammer blow - no ear defenders. (f) same idiot and his mate standing in the grind path - the guy doig the grinding was wearing the face shield, but is the one least likely to receive any hot grindings in the face !
