Unusual information: Where there are curves in railroad tracks there is usually a device called a wheel greaser that - when a train goes over it and activates it - pumps grease on to the wheel flanges so they'll slide along the rails with less friction.

I think everyone missed the part where he said they are an exaggerated example of train wheels. Should have said they are an over exaggerated example of train wheels. Also left out that each set of wheels is in a truck or carriage that pivots. So you have slightly conical flanged wheels that are on carriages that pivot to conform to the curves of the track.

Exaggeration and completely changing the base shape and then exaggerating that fictional version are two different things tho

Great demonstration and vivid video to bring home the key principle of rail wheel design. Thank you very much.

As a trackwork engineer, this is somewhat true, but there are several other variables missing. First of all, the wheels are a combination of a conical design and have flanges. The angle of the tread bearing surface of the wheel is also closely matched to that of the rail head. Another variable is that on a mainline, the rails are canted, meaning they are angled inwards. This plays an important part with the wheel to rail contact. Lastly, depending on the speeds and degree of curve of the track, there can be an elevation change of the rail to help the train steer.

train tracks also are extremely gradual in their turns....the coning is VERY small and minimal. Its hard to see in person even

It makes sense where trains can go over 100 km/h

It’s pretty cool if you think about how carriages are mounted to wheel bogeys as well. It’s like a multi-layer system where each layer deals with a specific problem. The conical shape deals with the wheels staying on the track, the wheels are then mounted on bogeys that can turn freely to allow this to happen as well, and all of that supports the carriage.

Best visual explanation. Ty

Cheers for this. I had no idea that's actually how train wheels work.

Forgot the part where this design completely negates rolling resistance, the force that causes heavy vehicles to deal exponential damage to the roads they drive on. Making it one of our most sophisticated engineering achievements.

The flange wheels are mounted on bogies or trucks that move.

Cant you take the simple flange wheels but cut them in half and have them attach to eachother by C hooks?

Cool.

Nice

Where can I find the files you printed? I want to 3D print that wheel and the track, they look cool.

This is an iron off-road) So many bends may only be needed in a certain place and for a special task.

Cones will quickly acquire wear grooves under high load due to small contact area. This will lead to yaw oscillation or hunting.

0:46 the train wheels on the orange track are stabilized by the weight of the train aswell

is micro center near madrid?

I wonder if the slight horizontal change in the center of gravity plays any role in contributing to the safe high speed turning and reducing wear & tear (improving longevity and decreasing maintenance costs)? (I.e. placing less weight on the increase in diameter spinning outside wheel during a turn...) Just posted a video addressing such issues.

Can we just mention the issue of hunting? Lets take the DLR for example, it has very tight bends so the wheels are more slanted than on most trains. This has the unfortunate effect of causing the trains to rock from side to side on straight portions of track.

people would be getting sea sick on the train, clean up in isle 1 lol🤣🤣

But suppose the tracks were banked for each turn? Then would flat wheels work during the twisting and turning process?

I'd like to know how the train/compartments are going to be (if not tipped over) on that "awesome" wheels moving in such terrains.

0:44 the example is obviously exaggerated but trains do oscillate IRL which can lead to the flange riding up the rail and derailing this rarely happens though since the train's weight is enough to push the wheel back down

The italian pentolino train buggy as been the reason why trains can go at high speed

okay, then what about the weight what is makes the train tracks fall sideway? In a weightless plastic modell seems to be ok

Where do i find this print

Are STL available?

Ok, so how does it work when you print proportionally right train wheels? Because the wheels irl don’t look cone-y enough.

Like a differential gear train.

Is it possible that the train can drop down turning right?

I made my own track and 3 different wheel designs. It does not work like yours. It simply turns 90 degrees and fails. With the track, i originally had square rails but noticed yours are fillet/chamfered so I reprinted a track with a slight fillet to it; i though this would change things, it did not. What's the secret sauce?? what is the width of the track ? what angle is the wheels?

How's the gauge of that track? Cone train.. yes

Not new cvt using this to squezze the cvt belt 2 cone each side

That must be why so many train derailments happen. There are probably companies that are too cheap to replace these when they wear out and lose their shape.

Does the train turn sideways into the curve preventing it from falling over as well or is that canceled out by the axels?

The tilt of the wheels on actual trains is much smaller than this, and there is suspension on the wheel carriers to dampen the forces out. Usually the tracks themselves may be slightly tilted if it is for high speeds, or if your really funny you design one of those self tilting trains like the British did

Actual train wheels have a combination of angled wheels with flanges. A reason is that the cones are really heavy if we would use then since the best way to keep them round would making them either fully solid or make it from really thick steel. And modern train wheels are also much more stable wich decreases wear and ads passenger comfort and faster travel. Just because they exist do not mean they are genius or perfect

This doesn't really explain what's happening. The "larger" wheel on the outside of the turn has to spin faster, so it "overtakes" the inside wheel, which results in the axel turning.
