I have travelled so many times in train....always think about this mechanism how it actually works?..this video explains everything....thank u...

This is a question that has bugged me for years and is finally answered in a most elegant way. Thank you Sabin. You've earned a subscriber!

I absolutely love how easy this was to understand. Moreover, whenever a question popped into my head, for example, about the crossing section being without gaps, the video continues to smoothly transition into explaining that without overburdening the viewer with all the information at once.

Even if you don’t understand English, you can understand it by looking at the schematic diagram. Very detailed, thank you

As a rail tech myself, the presentation is guite good. The current mechanism would be more complex due to the need for high speed through the switches, the gap is handled with another switch. So the wheel is smoothly pass through at high speed. And also the steering mechanism which consists of several lever on the boogie and its cone shape wheel keep the train inside the track while making a turn. Its fascinating watching these awesome tech..

My respect for the engineers is increasing day by day

It's such a great feeling when you understand how some everyday things work that you wouldn't have the chance to know otherwise!

Believe me or not, During my childhood I was so obsessed with trains that I understood this mechanism at a very young age, only by looking at the trains crossing the tracks.

Extreme props for correcting flange mistake. That attention to deal is what I'm subbed for

I understood the bendable tongue track part at a young age but always wondered about the fixed tongue track part. I used to think at that small point, the train can easily detail and maybe we just have to live with that part being very high risk because we don't have any better track changing mechanism. From this video I learnt about the rail check which make it basically impossible for the wheels to turn the other way and derail. It satisfied years old curiosity that I had since I was a child. Thank you!

This is beyond words. I always had difficulty in visualising all these mechanisms despite reading the theory several times. Millions of thanks to you for making this animation with a nice explanation as well. Thank you so much for this.

I have retired from Indian Railways service. So, naturally I am still curious to learn newer things about the functioning of the rail organization. On many occasions I watched the trains changing tracks.I was curious to know how it was done. You have explained the whole process in a simple manner. I hope to know more and more about the technical side of the working of railways in future.

Its amazing how even somewhat simple things like this have been invented by the human mind. Great progress and ingenuity here!

What a blessing to live in this generation. I'm in my early 20's. Thank you for the animation with the coherent audio.

I'm one of those operators in germany and I really like the video. It's a really simple but well explanation for laypeople and at the same time 100% accurate!

It's amazing to know that so many things take place in split seconds at very high speeds to let trains switch tracks safely. My respect for engineering is growing everyday with your videos!

Great explanation with fascinating animations--almost real. I like that you ask questions once a while and make the viewer think how to solve design problems. There are 100s of lectures and videos, but students just passively watch.

It has been years how this works and now finally, i got to know it's working. Really enjoyed...

Props to engineers, the unsung heroes of our days.

Now I know the technology behind the trolley problem! The design has to be robust so that the problem is valid. Thank you!

I understood this mechanism (only the track switching and the junction crossing) at the age of 11 for traveling in local trains many times. 🙂 Just feeling very happy that Lesics made a video on it. 😁😁😁

Every time I think I know everything > > > I discover that I only know a little !!!!! Thanks for this clear and interesting video.

Wowww finally someone with great commonsense skills can break this millions dollars question for everyone who been curious about this for years!!!👍👍

I was thinking about this mechanics since my childhood and no one ever explain me even snippet idea about this also with this much ease, and honestly this gave a clear picture about how whole mechanics works.. video was very informative thank you

I'm pretty sure that Thomas and Friends Fans knew how this works

*I found this channel randomly; it is really a channel that produces quality content. Congratulations*

I have always wondered how this track mechanism works, and many railroad people have tried to explain it, but this is the simplest and easiest way to understand how it works.

As trains pass over points, massive forces are applied to the rail elements, day in day out. It always amazes me that the structure survives this onslaught and metal fatigue seems to be rare . . .

When I was kid I used to watch track so carefully during my train journey that I understood all the mechanism when I was kid. Also later when I completed my engineering got to work in a Indian railway maintainance facility.

This is so cool. I actually write software for a company that monitors the output of the switches, but I have never seen a switch in action with this much detail. Very good explanation! Nou my graphs make a little more sense to me!

Very impressed by how simply this mechanism is explained in this video. Great job guys

When I Was Young I Had This Question. After So Many Years It I s Clear Thank You KZfaq For Recommending This To Me

How many of u r here after balasore coromandel tragedy.....well as per the primary investigation...the switch of coromandel track was not changed to main line and hence the train entered the loop line and hit the freight train...

I am working in indian railways as a trackmainters very helpful and knowledgeable information for me and every us 😊

Came across this video randomly. The animations and narrating were very nice.

My parents bought me a Hornby train set when I was 10. You took 6 minutes to explain what I learned in 15 seconds with my train set.

It never occurred to me that the tongue tracks actually bent to achieve switching! I thought they were just moving laterally from a closed to open position, not deforming. It always blows my mind when engineers utilize the plasticity of otherwise stiff materials to achieve the needed mechanics. It's so creative, and also requires balancing the added stress and risk of eventual failure of the complaint mechanism and the simplicity gained against the lower risk of material failure but increased complexity of a stiff mechanism.

I love how clever these devices are, wow!

This is far the best 3d animation instruction video on rail switching

THANK YOU 🙏🙏🙏🙏🙏🙏🙏!!! I watched at least 5 different videos trying to explain how track switching works and this was explained perfectly. I can’t believe I actually understand it. The engineering behind this is actually genius. Damn thank you again!!!🙏🙏🙏

As a railway engineer myself. This is very well explained. Thank you and well done!

Lesics please make a separate video on the working function of Diesel and Electric locomotive. Thank you 👍👍👍

I work as an engineer in Signal department of Indian Railway & its our one of most important gear. But yes it can be said as Joint Venture of Signal Dept & P Way dept (Rail Line or Track dept). Rail line related items maintained by P Way & connection from machine, all the connections for movement as well as electrically & circuit overlooked by us & thatswhy it is always centre of dispute between these 2 departments of railway. Its very very sensitive equipment mechanically, where even a millimetre matters & having very complex circuitry. Mind blowing equipment but labyrinth.🤩 Thanks to lesics, even my basics improved. 😊

KZfaq is a revolution. Years ago, these things used to be taught only in colleges without any kind of visualisation. Such a good explanation this is. Thank you!

3:40 High Speed Rail has another moving part to ensure a continuous rail surface. The frog (the point where the rails intersect) is also flexible and is linked to the switch. It is more expensive but also smoother.

My dad works in the railways so I got to learn this at a very young age, but seeing this mechanism with animations is really amazing

Finally after a years, KZfaq recommended me this video, thx. Such a great advice.

Damn!!! I had to find all of these by myself watching the rail tracks. I am glad that I got everything right.

I have been travelling on them now for about 15 years.... and I would have still continued thinking about this mechanism.... Guess I would never find it out.... But thanks to this video

Great video, I never thought rail tracks would be so interesting!

Well explained, easy to understand, no stalling or worthless info, great pacing. Thank you, this was a pleasant watch.

Thank you! I always wondered what the "wing" rails were for, and now I feel dumb for not realizing! It's simple xD

Beautifully done. Animation and narration are really good.

This is a very informative video. by watching this video I have cleared a lot of concepts about turning of trains on the crossing point. thank you very much Lesics for making this awesome video.

I've been wondering how this system worked since I first saw one of these bare rails when I was a kid. Playing Transport Fever 2 piqued my interest to a point where I need to find the answer pronto. This video finally answered a decades long question for me. Well done.

I've understood how this works all my life, but I love the illustration !

Wow! thanks for this awesome animation.. I clearly understood the mechanism.

What a meticulous and failproof design and operation! We hardly think about the nuances when we travel by train. Thanks for explaining.

I always thought it was more complicated but really it’s that simple!

This even goes into depth on potential stress points and design flaws! Awesome!

I feel excited just by knowing these things. I wonder how someone feels when they invent something like this.

This channel explains every interesting engineering invention so nicely that I hardly miss any video of this channel. What a great way to learn these interesting topics.

I hit the like button just by looking at the tumbnail. Im pretty sure it will interesting the whole minutes. Thankyou

Explanation of the mechanism happens to be excellent I have come to know about the unknown features, Thank you very much.

Have always wondered about it, since I was child. Thank you this was so informative and easy to understand, :)

is this a re-uploaded video?

This explanation can't get more perfect than this. And that's a fact.

simple yet brilliant. can we take a moment and appreciate all those engineers who have painstakingly solved seemingly simple problems with years of hard work and innovation. beautiful explanation by Lesics.

Wait. Ive seen this before

Simplicity and nice visuals are key for understanding. You are amazing in explaining things easily with both. Thanks.

If you’ve ever been on a train you might’ve noticed that as you pass over a track switch you hear a “ga-dunk ga-dunk… ga-dunk ga-dunk” regardless of which way the train goes, that is the sound of the wheels passing over that gap

I wondered how these worked, I mean I knew the basics, but I still found new things in this explanation. Great

My husband is a railroad engineer and told me how it works, we also have trains under the Christmas tree and he’s playing with my 2 year old grandson he’s molding my grandson at the early age, sometimes I wonder when is he gonna be tired of trains.

Sir, was this video uploaded yesterday too?

I was scratching my head so long with those gaps on the track… thank you for explaining in a simple way

This is some brilliant physics right here. Transportation like cars, rail and aviation never fail to amaze me.

This is well presented. Please be aware that names change from region to region and railroad to railroad. For example in the Midwest the tongue tracks are commonly referred to as points (the section that gets replaced) and the switching rods are often called bridle rods.

Good video. I find the engineering and physic of trains/tracks interesting. Another video idea would be the physics of how train wheels are conical and for the most part stay on the rails using geometry rather than relying on the wheel flange, which is just a safety device. Also another video I'd like to see would the physics of how the rail tracks and sleepers stay in place. Rail sleepers are just bedded in crushed rock (called ballast). I don't understand how the massive weight and inertia of trains don't push the rails and their sleepers out of place. I've asked this question on Reddit but noone was able to give a satisfactory answer. Also how rails deal with heat expansion/contraction - why miles of train rails don't pop out of place on a hot day due to expansion.

I've been trying to wonder how it works, thanks to KZfaq recommending you to me at 8:30 Am, I was finally enlightened.

Wow 🤩 What an awesome video.... Amazingly explained

Didn't you post this yesterday?

Now I can die in peace

I already know about how train switches it's track, but you gave me extra information about check rail and other components also. Thank you

"Hey, so how do trains change the tracks?" My brain at 1:30am out of nowhere. So now I'm here.

Reupload?

Reuplaoded ??!!!

I’ve always loved these railway mechanics and how they worked, but I’ve never had the opportunity to see them in real life, let alone see them so beautifully animated. These are amazing! I hope you can produce some more stuff to do with railways (maybe funiculars or cog-railways? It’d be even cooler to see historic wooden/gravity railways as well!)

Didn’t get bored the whole time…amazingly explained…

Is it reuploaded or I have just time travelled.

Are these design pointers valid for monorails as well? Or just standard trains?

Finally ! The video i have been waiting to come as a recommendation ! I am thinking about this for like 10 years. Since I drive the Sbahn in Germany. This is great. Thx Never searched for it tho 😂

Feels good to know that I figured this out when I was kid, by looking closely at the crossings on my model train set.

This video didn't talk about how merging trains can derail if the track switch is set to the wrong position.

A train doesn't need a steering wheel, the rails steer the train.

I will be driving on Monday so am happy for these information with what I have already get in class thanks every much well appreciated

Wow, so clearly explained and well visualized! You are the best!

Re-upload

Is any one Have Deja Vu with this video...

Superb & complete explanation... answers all relevant question in my sense, couldn't have been better..!!

Never seen such a crystal clear explanation.
