It's amazing what you can learn round here but I wouldn't call it an education to die for.
An education worth dying for.

Feynman explains the tapered wheels on a video I once saw.
And when you think about it, a differential for each train axle coordinated by a computer system would be rather expensive for a freight train, although some engineer might come up with the idea for unknown reasons.

Did you know that the one part of the wheel that is in contact with the rail (and the same applies to any wheel and surface) is stationary even if the rest of the train is moving?Philosophy Explorer wrote: ↑Fri Jun 02, 2017 11:03 pmAnd did you know the top part of the wheel is moving faster than the bottom part of the wheel?Harbal wrote: ↑Fri Jun 02, 2017 10:59 pmYes but did you know part of a flanged wheel is always moving forwards while the train moves backwards?Philosophy Explorer wrote: ↑Fri Jun 02, 2017 10:52 pm

And that is totally unnecessary because a tapered wheel does it automatically.Walker wrote: ↑Sat Jun 03, 2017 11:58 am Feynman explains the tapered wheels on a video I once saw.

If you are watching a train and you hear the squeal, that is usually when a flange is in contact with the rail, and the thumping is usually a flat spot on the wheel from the brakes being applied and the wheel sliding on the rail.
