How trains REALLY turn

Trains only use their flanges on the sharpest turns!

Merry Christmas everyone. Especially those that got bored of their family and are now watching this video.

If you have ideas for videos like this, leave a comment, I read them all!

*they never have to use their flanges on sharp turns *unless it’s a pacer*

[redheadedhermit]

the invention of the train engine was good, but the design of the wheels and the track change system, is just one of the coolest inventions I've ever seen

> trains never have to use their flanges except for the sharpest curves

Kid named hunting oscillation:

[DJmcRUSH]

Those flanges are CONSTANTLY being worn down. Every curve, every switch, every guard, every frog. There's a reason they're made as thick as they are.

[rutmerplayz]

Never knew shorts could be 3 hours long.

[TheSleepSteward]

Dude, this guys has the absolute cleanest and unnoticeable loops.

[gangsterman]

All these shorts are more than informative. It’s art

[deff]

The only correct way to make looped shorts

[ricktopeka]

Congratulations. That was one of the most seamless loops on YouTube. Oh, and true about the flanges as well.

[KingFoxiFox]

The passengers in the train are scared that they are stuck in a loop xd

[depon]

The guys in the train: WHAT THE F- IS HAPPENING! I WANNA LEEAAAAVE

[benkayvfalsifier]

Okay, that's it, I'm subscribing. The shorts are perfectly looped, short, informative, and easy to understand.

[Manny]

Ive seen others do this but this is still an amazing video and can help some people understand it better

[rahulpathak]

And one of the important sharpest curve is point where train changes it's direction by track changing .

[akshay-xt]

Make that kind of a triangle like slope in the wheel and it will derail even in straight track. There is another problem with conical wheel. Its called hunting oscillation.

[the_wolf_cub]

I watched the video three times before I realised it loops. That was really smooth

[Naren]

I still remember the time when IG users tried to be interesting and superb by stating that these "Concepts" won't work because (*Instert awful reason*) Not knowing that trains always been working like this 😭

[speeedycrafter]

Thank you for explaining this, I’ve been contemplating this for weeks

Train mechanic/fitter here, In the UK at least, Train wheels have different profiles dependent on where the unit is expected to be used in service, P8 is the most common here, which is based on a worn P1 (Virtually a 90 degree profile), which is what rolling stock used to run on. I beleive in scotlant and other mountainous areas they use P11 which has a much steeper angle on its wheels to negotiate the tighter turns expected on such tracks.

Interestingly some trains have 3 wheel sets per bogie, and the middle wheels have to have a thinner flange to accommodate for the turning arc of the rail between the other two either side of it. Commonly used on freight locomotives.

Additionally Between the bogie and the wheelsets there are laminated steel and rubber chevrons, which also help hold the wheelset tracking to the railpath.

Best information page currently. I've learned more from these videos then any others so far. Bravo and keep doing what you're doing. Love it
