This is also an excellent example of chaining fall-through in assembly language programming. Each switch determines whether to divert from the straight track.

Great graphics...it is very easy to understand the 3 way crossing .. thnks buddy.

Wonderful! Incredible amount of information in incredible "simplified" graphic form. Thanks.

I use the train station, called "Ярославский вокзал" at Moscow metro station "КОМСОМОЛЬСКАЯ". It is one of the "VERY BIG" stations! I always seeing switches and switching cross (when a simple cross rail tracks, but also you can drive at left side. At this switch you can go only straight or left (at one way)). I never understand how it is works).

_Lapped_ is short for _overlapped_ , two turnouts overlapped onto the space of one. British terminology - _sleepers_ in the US are _ties_ . In the US a _crossing_ is where one railroad or a road intersects with another railroad, often called a _diamond_ ,and not where they share a track as in a turnout. Nice animation.

That's *not* a three way turnout, that's two overlapping standard turnouts. Three way turnouts have double points and are roughly symmetrical. They are also fragile, expensive to manufacture and difficult to maintain, which makes them very rare.

I really love three way switch tracks. It's two of my favorite train tracks of all time. The other one is the double slip switch.

Thank you, this video is very easy to understand

Great I love switches turnouts etc, in fact I love them more and the trains themselves so clever!.

3 D images. Love the tracks & trucks. Look 100% realistic. Great illustration on this video. 🎥 🛤

🌹VERY VERY GOOD AND INFORMATIVE VIDEO.. I. REALLY IMPRASSED🌹Very good creativity🌹so thanks🌹👍

Terminologies used are spot on. Really good video

Your animations are phenomenal.

Impressive video about railway crossing from left, right, and straight! : )

Perfeita simulação! Parabéns!

Very entertaining and fun to watch. Thanks for posting this.

Sehr gute Darstellung , sehr verständlich gezeigt , einfach genial

Super video combined with an awesome music

This explanation was just beautiful 🙌

Amazing animations 👌👌 Good luck for ur future videos.

Wow...Awesome animation. Please keep going!

Fantastic explanation!😃👍👍

Very interesting and informative video. Great animation...I actually learned something! Thank you for creating, uploading and sharing! 🚅

Your video making is absolutely fantastic bro..

Good work with nice graphics. Thank you.

An easy explanation, thank you.

Nice vid, we usually call them points though, but great job none the less!

分かりやすかった

Thank you for your hard work.. Another informative video thank you

Espectacular!!!!!

A best animation

Brilliant - a joy to watch and I like the quiz.

Nice informative video. Thanks 👑🌐🌴🚅🚄🏆💞👍👍👍

Simple and straightforward. Are you a track engineer?

Basically it's just 2 track switches at a very close distance making it look like a 3 way joint From main track to sub track and from sub track to sub sub track

The graphics are great. But, the written info at some points is removed from screen too quickly.

நல்ல இருக்கு

Good information

muito interessante !! gostei !!

very nice video to see how it works ty !

nice 3D Animation

Incredible,,, Thanks a million

Muy bien e interesante

Very informative video

Great animation!

awesome.😊

Which software are u using for animation??

You forgot the fourth state. Since there are two "binary" switches, the fourth state is called self destruct. It makes the train fall off the tracks.

awesome graphics !!!!

Nice

great animation, i like it!

Good❤❤❤❤❤❤❤❤❤

Amazing!

wonderfulllllll!!!!!!!!

Great

Cool, it is very informative.

It's essentially not really a "3-way" in the strict sense, but two 2-ways right after each other.

Very interesting!

excellent video!

3:00 are your sure about the stretcher bars? In your video you see four rods from the POM to the tongues rails. Two of them are responsible for the changeover. The other two monitor the position tongues. If you have a fixed strecher between the moving rails, you only need one rod to move and one two monitor as the opposite rail always do the same. So there is no fixed rod between the tongues (at least not in the front near the tip) The two tongues move independently of each other and for different lengths of time. The tongue that opens the gap moves slightly longer than the tongue that closes the gap. This makes the gap slightly larger and the flank of the wheel passes better through the gap. By a clever mechanic in the drive, the adjacent tongue is locked at the same time. The monitor rods just check if both tongues reach there end position. And if (for example) a train split the points, these rods are moved and and alert the signal box. Regardless, your videos are great and I've forwarded them to families with children. So they learn technology and English in one 🙂

Soo nice

Really Good

if a railway is using a double or even triple gauge, than the switch is a little bit complicated. I knew this since I was in high school, as a basic knowledge in rails drawing railfans world.

0:51, With the grooved rail, Does the flange sit inside the groove or does it sit on the other side of the groove?

Nice 👍👏

Than you so much😍

Thanks

Terminology is significantly different in the U.S.

I have a question. While the train goes directly through the straight track ( last scenario at 5:21), there are no checkrails that preventing train to derail from frog location. How is it possible to be considered as a "safe design"?

TQ sir❤❤❤❤🎉🎉🎉

basically it is just two normal crossings behind each other

А что же при движении по прямой забыл нарисовать ещё два контррельса напротив крестовин?

Keep it up Bruh

Is it operable? or only a design? Can you present a video where this type of crossing is used? or only deceit?

In fact it is shown that there is NO 3-way crossing, but instead 2 two-way crossings short after another.

ive seen some train fish plate connested then welded for even more strength

Oh, so it's just 2 normal switches but placed so close together they overlap each other.

Зачем так усложнять конструкцию когда можно поставить левую и правую стрелки одну за другой?

i never know its bending the steel, rather than having some kind of hinge. ik its only a slight bend but will it causes any problem over time?

👍🚞

2:34

I did not think it would be possible

2:05 Why this joint pieces are called 'fishplate'? it looks nowhere like fish nor has anything related to fishing activity.

Right

Which program? Please

👌👌👌👌👌👌👌👌👌👌🙏

Nice! And i have a question. Does anyone know who invented the idea of creating the first three way switch train track? Because i'm just curious.

And where is the stretcher bar for the 2nd rail arrow? It looks dangerous

Could you show symmetrical three way railway crossing?

During the loop chance if the track gets blocked by any debries or any thing and prevents the mechanism to change ta track what will happen it will cause accident I think this is the main cause of the coromandal train accident the loop line was engaged and the the track didn't change its position and thus cause the accident

In fact, its double 2 way crossing )

@2:13 that would be _tapered_roller bearings

How is this not just two switches really close together?

Graphics are Great HOWEVER many of the captions are just to fast & I kept finding that I'd ha e to rewind & freeze to try & read what was said..

Crossing? Looks like a 3-way turnout to me. Or two overlapped turnouts, actually. I don't see any crossing.

......SO,I GUESS THAT IMPOSSIBLE TO CREATE EXACT 3 WAY CROSSING SO 2 2-WAY IS BEING USED =BUT I SUPPOSE THAT IT'S VERY POSSIBLE BUT A DIFFERENT THING IS TO BE DEVELOPED,EVEN THOUGH IT'LL BE ABOUT 2 POSITIONAL SWITCH BUT IT'S MORE APPLICABLE FOR REMOTE CONTROL,THOUGH
