Plane on a treadmill! 9pm, Discovery Channel!!

The trajectory of the smoke particles would be slightly different to if there were no wind speed, they do after all have a forward momentum. However, as the smoke particles are so light, in practice, it would be very difficult to notice any difference.

However, if the wind was blowing from behind the train, that would be a different kettle of fish. To an observer travelling at the same velocity as the train, the smoke would appear to stay largely stationary relative to the train.
There, hat thrown into ring!

If your hat was thrown into the ring while you were on a treadmill with 2 ducks behind a hat and 2 ducks in front of a hat and there was a strong headwind blowing... would anybody care?

Someone in Bangkok would.

They would get to laugh at me falling off...

I think you've got it backwards. If a steam train was travelling at 120mph and the wind was 120mph in the same direction then there's a fair argument that the steam would look like it was rising vertically above the train.

It was meant as a jest!

Express trains (today) are electric, so obviously no smoke, or steam!
But you didn't suss it!

Plus you read it all wrong!

Let's see Adam and Jamie sort that one out!

I didn't read it wrong. That's why I said you'd got it backwards.

If the wind was with the train then the smoke would rise in a vertical line. Ish.

Yeah but, no but . . .

The wind wasn't with the train! It was going into/against/towards the wind, not WITH it!

Are you bonj??

I know the wind wasn't with the train. Which is why I said you'd got it backwards.

As you described it there's no puzzle, which is why you said you'd posted it. Unfortunately it's too similar (backwards) to a real puzzle.

How did you get Dayvo's password, Bonjwold?

Fair dos!

I interpreted 'backwards' as the 'wrong way round', which isn't what I meant! However, I do now understand your reasoning!
