How do trains change the tracks?

Trains are able to change the their trajectory with just a slight adjustment of the rail track. This clever switching design is achieved with a simple trick on the wheel and track. In this video we will also learn about rail crossing, wing rail and check rail. Let's take a closer look at how it works!

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!

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.

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

My respect for the engineers is increasing day by day

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..

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

[ExpertBustice]

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.

[arwahsapi]

Props to engineers, the unsung heroes of our days.

[pizzlesauce]

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

[SALESENGLISH]

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.

[HowdyHartholz]

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!

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.

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

[sourinbasu]

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!

[jamesneilsongrahamloveinth]

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 . . .

[ScienceSeekho]

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.
