The shape of the wheels helps a lot, but keep in mind the turn is banked as well. This is not only for passenger comfort but helps keep the center of gravity between the rails.

[YoungGandalf]

Caution: This vehicle makes wide turns

I like that the last train shown had a bloodspatter.

[LBSCR-Productions]

some trains (mainly high speed passenger trains) have a tilting mechanism helping them navigate curves easier.

There's also the banking, trains of any type bank into their turns wether it's a lot or a little depends on the type of rail but all rail is banked on the curves that shift the momentum and center of gravity

[jakubznojemsky]

Furthermore cabins of some trains can get tilted inside the curve. If not curves are usualy designed with outer rail being bit higher so combined gravity and excentric force (inertia) go right against the floor. Similar aplies for some roads. It needs to be designed for right speed otherwise you will still feel like falling otside or even inside the curve.

Anyone else noticed the blood on that train at 00:48 seconds into the video?

[clydedenby]

The blood splatter on the nose of the last one....flawless victory.

Considering the tires most people have on their car they would lose traction way before the risk of rolling over would become a thing

[pags]

The bus footage is from a movie called Speed, for those wondering

[frazzel]

That last train with blood on it really gives a meaning to “the bullet train” 😂

[ScotlandsGold]

That bullet train at the end still has its lunch on its face

[rickyhineman]

The Japanese approach is to just tilt the train itself to counter the g forces of turns. This sounds odd, but by having an active suspension system that uses computers to automatically adjust itself for corners allows them to not just take the turn at bullet train speeds, but take it so smoothly you (as a passenger) wouldn't even know you're turning. It's absolutely incredible engineering

[Ascertivus]

“Banking” the turns (having the ground higher on the outside so the train tilts as it turns) is also used to keep trains from derailing!

[lbscrterrierstudios]

In the 80s british rails created a train that straight turned a bit like a motorbike it would tilt down

[M.K__]

Nice of you to show the turns clearly.

[Vibeant]

There was a train wheel demonstration using large cones on tracks. That was the best demonstration of this concept.

[dodecaheathen]

A lot of them have tilt function too like the Pendalinos in the UK

[cheecheneg]

There are also tilting trains designed to deal with unbanked curves. They tilt inwards to counteract the centrifugal force.

[ziljaeyan]

This also helps with keeping the trains on the rails as if it runs off to the side to much the conical shape helps shift the center of mass inward keeping the train inside the rails, plus theres a lip at the end as a last resort in terms of simultaneously braking the train and keeping the train from jumping off the rails, it is a marvel of engineering, simple yet very effective and so its maximum efficient
