No.
congrats on the sponsorship !
so it's basically the same idea as drilling a tunnel, one machine can do everything to the point where on the front there's nothing and out of the back comes out an already built and ready to use rail
Have seen these machines at work in India. Infact there was actually a sizeable crowd the first time people saw them working. Everyone was awestruck.
Hahaha 😅
Just something about watching the track layers that is so satisfying.
Insane engineering behind these machines... Wow!
Indeed
Plasser & Theurer makes almost all of these machines an Austrian company from the city I live in.
One type of track maintenance machine that was not mentioned in the video would Rail-Head Grinders. These are common to railways of the US and Canada, but can also be found in the UK, Australia and India. Most commonly they are manufactured and operated by Loram Maintenance of Way Inc. of Medina, Minnesota USA.
What do they do?
@@neurofiedyamato8763 rail heads wear down over time, usually in uneven patterns which can cause poor ride quality, when this happens there’s usually 2 options, replace the entire rail, or grind down the rail head so it’s uniform again
Here's an example of a high speed rail head grinder. Looks scary in action; ua-cam.com/video/s38VVmlV7kc/v-deo.html
As a child I did love that machine so much, it looked so spooky as it did come in the night flames spewing from its sides. I called it "The dragon" wander why. Any way it seems to have been taken out of service in and around Norway's capital, haven't seen it for years. even if I do live very close to pretty much every rail that travels north from the central station. I do live where the lines do diverts into the three mainlines for northbound trains, so I should have seen it if it was in use anymore in the central parts for the system.
In Germany and Switzerland we even use High Speed Grinding developed by Vossloh.
incredible efficiency, there was never a road built that could ever match the cost effectiveness of a train that can service its own track, just amazing.
You've got to admire the work done in designing, developing and operationalizing such machines. Great work and great video
These machines are incredible. Crazy engineering!
Straddle carrier and full span girder launching machine is also used mainly if not exclusively in Railways construction.
Viaduct is assential part of HSR, it is highly used by China and now in India.
This seems so much easier than building roads ^^
Both are very demanding and complex, but it is hard to say which is more difficult...
Does it actually?
Thank you sincerely. I had been looking for this kind of channel for quite some time!
Spasibo.
I work for 7 years now (and not for long anymore) for one of the most important compagny of this business of building that type of train and I learned more on the way that a tamping machine is working with your video than in my company on 7 years, even if I worked only on that type of contruction/renovation trains.
My chef team asked few times for a budget to go on a trip on restoration work site to see our work doing is job, be able to understand why some things have to be done in a specific way, etc. Always denide... "we can see it working next to the halls" but only tamping so I still don't know all other fonctions are working.
Good products, compact compare to some seen on your video, clearly one of the leader of this market but I let you imagine the inside with the previous paragraph and the fact I'm not going to exceed 7 years here.
At least, it has not a direct impact on the good functioning of the products.
Your vides are awesome!!
Thanks
Super youtube channel, pozdrav od zeljeznicara iz Svedske.
Hvala puno, pozdrav!
Me the son of a industrial engineer who is manager of my provinces tracks : Oh i learned this at 10
Great explainer video. Maintaining the railways really are a large operation. Keep it up👍
Thank you
Great informative video thanks!
Thank you
Does the ballast machine also tamp, or does it always need a tamping machine to go through after it? How often does a track need the ballast to be tamped or cleaned?
There are ballast cleaning machines that do tamping as well
Just a request, can you play the intro sound quieter? Every time a new video starts the whole house wakes up
Headphones are the solution my friend
@@MrJimheeren so you want them to experance hearing loss. thats pretty mean of you.
@@Aliceintraining Oh lord!
@@Aliceintraining can’t you like turn the volume down?
@@min-hokim1614 I use headphones and seriosuly, I can have it set where its consistently normal and audible for most things. but when ad's or some intros come on, they are not normilized to the audio level and it really hurts my ears, whats worse, is that they can play before you can get to the audio controls. then once you fix the audio for the stupidly loud part, it gets quite and you have to turn the volume back up for the main video.
there is zero excuse for not normalizing your audio on a edited video . its just unprofessional. the rest of the video is fine but seriously.
in case of welded rails, like depicted at 4:53 - how does these type of rails handle shrinking and expansion of metal due to temperature changes?
i thought the gaps were supposed to provide that slight change in length
In my country we use both welded and joints. I believe they use the joint type every several hundred meters with some gap in them, and the rest are the welded type
They don't change in length (only a fairly short length at either end of the welded rail section moves) but temperature changes build up internal stresses within the rails. The ballast bed and concrete sleepers prevent these stresses moving the rails horizontally and vertically.
In CWR (continuous Welded Rail) technology, the rails are welded at a specific temperature (around 25°C) and prestressed when welded. Due to this conditions, the rails will absorb the difference of temperatures all along the year without moving, of course if it stayed between the mechanical limits specified to the welding conditions.
Overall a superb, extremely informative video.
Glad you liked it!
Great and informative video 👌
Thank you
Thank you for this amazing video!
Glad you liked it!
please make a video about electrification
Will be
Awesome video. Freight movements is vital for the world if railways weren’t built and everyone would of been stuck.
Thank you

great video I love trains due to my autism and also cuz trains are cool
Glad I am a part of Plasser and Theurer
Bist du also von Linz?
@@florianix8272 nein, ich bin aus plasser india
This is the most interesting thing I've ever watched.
I mean, this is quite literally a mobile railroad factory.
Holy shit.
these are so cool honestly
Definitely!
amazing video!
Thank you
Yeah I do
I work with them in India
And what is the experience of operating such machines?
@@RailwaysExplained It takes a very high discipline to operate.It's weight and length makes it very difficult to look and notice all around it. High pressure upto 150 bar is operated in these hydraulic hoses in very cramped spaces,which is a very serious headache in its own way when any leakage is noticed and hoses needed to be changed. During operating in limited block time, if the machine is in ok condition and maintained fit,it is good to operate , though you still need to look out for any instances of failures. Because due to limited time,you have to clear out the section because if you dont then there will be cascaded delaying of the trains that would be running on the track and upper administration officers wont care about your explanations anymore and as an incharge , you will be penalised accordingly with disciplinary actions.
Great video
One of the best!
Thanks!
One proximity sensor failure the track laying machine comes to grinding halt?
I mean I hope there are redundant sensors…
看起来很有趣，视频做的很好
谢谢
There's currently one of these in hungary, rebuilding the Szeged-Röszke train line.

Great! Thanks for share
amazing video
Thanks
When Finnish railway is coming
Will be, but we can't say exactly when
I work at Plasser&Theurer:)
why u cant even mention the manufacturer or its origin?
and btw, there is also a "train", that moves continually, that replaces the rails, the slippers, removes the bed, whash it(and adding some new) and then laying all these things back in place
3:36 india🇮🇳
By railway workers going on strike or sat on their ass drinking tea or coffee
In all fairness them methods are so clever
yay, i am officially a dedicated rail lover ^-^

Good information about railway please visit the pakistan railway and one video on pakistan railway
Skip da ad 6:50
Mechanics working on these making bankkkkkkkkk
Can you do Poland railways explained please? Thanks!
It will be very soon 😁
I need it
Wow.
Great.
Are railways level or curved?
What do you mean?
@@RailwaysExplained I mean, are railway tracks level, horizontal, straight? Or are they curved and bending up and down?
😍👍👍👍
Thanks for showing off a whole bunch of tech that dramatically reduces costs and increases efficiency that my country blatantly refuses to ever use.
Hopefully things will change for the better...
If California High Speed Rail is a good indicator, that's unlikely anytime soon.
@@travisbeagle5691 Highways go over time and budget all the time, just that no one complains. The California HSR is actually not all that bad.
@@parsahasselhoff7986 I'm not against the project as a whole, the problem is the execution is terrible. Their planned phasing is bad because it connects two places that are effectively in the middle of nowhere to each other instead of connecting at least some of their major cities first. Their The huge litany of laws that the state has put in place over the decades make it damn near impossible to do anything at all in that state. Then to make matters worse, the construction techniques they've employed to date are inefficient and therefore more expensive than other alternatives that they could easily have went with. Frankly the state has no business even considering the project when they can't even build housing without it taking a decade and costing 3-5 times the estimated cost.
@@travisbeagle5691 Interesting, thanks for the info!
Coolies crucified under western rail transit tracks.

I really want to like this channel, but besides the jarring English, there are just way too many errors in this video. The whole video feels like a mashed up reading of machinery brochures without any comprehension of the actual work. Also, a lot of North American and European machines and techniques are shown as if they work together, while they are in reality working vastly differently. I know that this knowledge is hard to come by from the internet, but this video doesn’t do it any justice.
This is a Better video , Compared to the Drastic Music only video ! That a Government might show in its Realection ! Properganda ! Achievements ! That said , Like the Railways in General , New videos can be made to the Absolute beginings of a Railway Construction , ie Excavation of rali land in first video , then Either old wooden sleepers being pulled up ! ( Next video New slepers being laid( next video) old Rail track being pulled next video new Railt rack being laid ( next video ) Welding of rail next video old Ballast being pulled uo ( next video ) new ballast Being wahed and relaid mnext video ) etc etc etc Next Videos ) So if a you tube person is wanting to see something Specific and in more Detail then hopefully thst is Given to them , also the people that laid the Original Track woukd have Certainly Dreampt ! Of having Equipment like this back then !
Aldous Huxley said "only idiotic morons are satisfied with laying rail transit tracks since intelligent would go insane if forced to do so".
would've been 10/10 until the ad 1/10
Why are you calling rail ties slippers ?

Hello neurodivergent community
what is the average price for this swietelksy machine ? Millions of dollars or Billions?
Машина одна все делает и работников мало, а в России у нас работников нагонят и машины ломаются .
Probably one of the biggest manufacturer of Heavy rail machinery is Plaster Theurer of Austria.
en.m.wikipedia.org/wiki/Plasser_%26_Theurer
Don’t give Micheal Bay any ideas !
Good one 😅
Still not remotely as good and impressive as the Chinese! We’ve got a long way to go!
Motorways and airports are better.
how can we humans create machines like this without showing it to the world? why do i have to find it on a youtube video?
Someone needs to go to speech therapist before making videos.
Slava Ukraini
Enjoy some good old can_cer! :D Slava Putin and The Russian Federation! To hell with all the braindead russophobic neo-Nazis!
I pi$$ on ukraine and its supporters! :D
I'm wondering about modern tracks that are welded together, how they prevent the track from bending when it expand in really hot day?
