Missing part in this animation.
*** Check rail basically guides wheels near the junction so wheels do not hit crossing nose section. In this animation one more check rail supposed to be placed (inside of straight tracks' left-hand rail)near the three crossing noses. So wheels do not hit the crossing nose section(right side crossing nose on straight track while viewing toward train's moving direction )while trying to follow straight track as shown in last bogie motion.
This video explains how a railway turnout crossing works and how a little complex 3way lapped turnout makes possible switching to 3 rail tracks one at a time. Means an upcoming train on a rail track can be send to one of these three diverging tracks .
Just watch the video, you will get it.

Great graphics...it is very easy to understand the 3 way crossing .. thnks buddy.
This is also an excellent example of chaining fall-through in assembly language programming. Each switch determines whether to divert from the straight track.
Wonderful! Incredible amount of information in incredible "simplified" graphic form. Thanks.
Terminologies used are spot on. Really good video
Expect they are point rails not tounge rails that are moved by the point motors.
@@Ghauster The rail which is moved by the motor is called tongue rail while the stationary rail is stock rail in IR terminology
Great I love switches turnouts etc, in fact I love them more and the trains themselves so clever!.
Yup, the trackwork itself is beauty.
Your animations are phenomenal.
Thank you, this video is very easy to understand
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).
3 D images. Love the tracks & trucks. Look 100% realistic. Great illustration on this video. 🎥 🛤
Very entertaining and fun to watch. Thanks for posting this.
This explanation was just beautiful 🙌
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.
I created the double slip switch crossing too. check out in the channel if u have not seen it yet.🙂🙂
Superb POV , never seen any thing like this.. All the best for all your future videos
Impressive video about railway crossing from left, right, and straight! : )
🌹VERY VERY GOOD AND INFORMATIVE
VIDEO.. I. REALLY IMPRASSED🌹Very good creativity🌹so thanks🌹👍
Very interesting and informative video. Great animation...I actually learned something! Thank you for creating, uploading and sharing! 🚅
Super video combined with an awesome music
_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.
Wow...Awesome animation. Please keep going!
Good. Very easy to understand. Super
Sehr gute Darstellung , sehr verständlich gezeigt , einfach genial
Fantastic explanation!😃👍👍
this video is brilliant its the best in the world
Brilliant - a joy to watch and I like the quiz.
An easy explanation, thank you.
Great animation!
nice 3D Animation
Thank you. :)
Good work with nice graphics. Thank you.
Very informative video
Nice vid, we usually call them points though, but great job none the less!
Don't miss last 3 mins of this video and like,subscribe and share if this video deserves it. 🙏
Nice informative video. Thanks

Very nice
very nice video to see how it works ty !
awesome graphics !!!!
Simple and straightforward.
Are you a track engineer?
Good information
Incredible,,, Thanks a million
Perfeita simulação! Parabéns!
great animation, i like it!
A best animation
Your video making is absolutely fantastic bro..
Amazing animations 👌👌 Good luck for ur future videos.
Which software are u using for animation??
awesome.😊
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"?
Dear colleague you already know this answer. Because you are expert turnout designer. 😎
There are check rails out there too, I've encountered them many times.
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.
Conductor here. Had something like this at our old roundhouse. We called it a puzzle switch.
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 🙂
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
excellent video!
Nice
Very interesting!
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?
good question.. but sorry! I don't have the exact answer of your question. In this animation ,it's not the exact copy of real thing.. it's only for educational purpose and easy understanding..
as you mentioned in reality it's slight bend and oneside hinged to heelblocks.. different problems can come up in this mechanical assembly, that's why schedule maintenance, repair, replacement done over time.
Steel rail is malleable enough for that length. It is regularly monitored and maintained by concerned staff and they are replaced after they earn a number of weight over the year(and ofcourse replaced if any fault is found).
Some narrow gauge rail jucntion have hinges on then as the rail are not long enough to bend on its own

this is just 2 Ys, overlapping each other a bit. You can see the two turning points. the first intersection decides if you go right or straight, the second, which looks about 10ft further, decides if you go straight again of if you go left. The only difference with normal Ys intersections is the middle part, the twwo overlapping intersections means you have one more crossing for the wheel approximately ion the center. We can see is a bit offcentered to the right, again, thats because the second intersection starts 10ft further. It;s a neat design, but I thought this would actually split in 3!
Muy bien e interesante
Which program? Please
Really Good
Amazing!
Espectacular!!!!!
TQ sir❤❤❤❤🎉🎉🎉
Cool, it is very informative.
0:51, With the grooved rail, Does the flange sit inside the groove or does it sit on the other side of the groove?
Great
Is it operable? or only a design? Can you present a video where this type of crossing is used? or only deceit?
Than you so much😍
Good❤❤❤❤❤❤❤❤❤
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.
நல்ல இருக்கு
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.
THANK YOU! I can get married now
It's essentially not really a "3-way" in the strict sense, but two 2-ways right after each other.
for normal understanding, you can say that but if you noticed the design carefully...it's a lapped 3 way crossing.. or lapped turnout crossing.
@@workingsgotanimated Yes, if I understand you correctly, I misspoke and should have called it two 2-ways _overlapping_ each other?
@@magnushmann yes
Nice 👍👏
Thanks
The graphics are great. But, the written info at some points is removed from screen too quickly.
I've heard of "tapered roller" bearings that are used for bogie (trucks in North America) wheelset axles but what are "roller tapped" bearings described at 2:10? I'm guessing it's another A.I. boo-boo.
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
There is fail safe system to indicate this. The green indicator will only turn on if the mechanism set on its right position. Don't understand how is it possible that it indicated wrongly. These systems do have multiple circuits if one fails another work.
wonderfulllllll!!!!!!!!
I did not think it would be possible
ive seen some train fish plate connested then welded for even more strength
muito interessante !! gostei !!
Soo nice
2:05 Why this joint pieces are called 'fishplate'? it looks nowhere like fish nor has anything related to fishing activity.
What happens if the train is going in the opposite direction and the switch isn't orientated in that direction? Does it derail?
Most likely, yes.
It will derail because the flange runs over the rail therefore pushing it away from the other rail.. Or in EXTREMELY EXTREMELY EXTREMELY RARE cases, the flanges will land back in the tracks.
Keep it up
Bruh
It's missing guard rails for both frogs when going straight.
Yes. I agree.
If train wheels do not steer,why steering wheel exist in driving cabin?
It’s not a steering wheel, and most trains don’t have those anyway. They’re the accelerator - a wheel instead of levers, buttons, or electronic sliders.
@@Twittler1 Thanks a lot,for the information.
basically it is just two normal crossings behind each other
Terminology is significantly different in the U.S.
Oh, so it's just 2 normal switches but placed so close together they overlap each other.
And where is the stretcher bar for the 2nd rail arrow? It looks dangerous
V were manufacturing these for IR
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..
point noted.
Could you show symmetrical three way railway crossing?
Right
How is this not just two switches really close together?
In fact it is shown that there is NO 3-way crossing, but instead 2 two-way crossings short after another.
Brilliant
This system will used becource it take less space on a station or emplacement erea
