Answer 1

Imagine a pool on the train. You could swim in that pool normally (aside from any bumpiness in the tracks) just like in a stationary pool. Why? Because the pool and the water inside it are all moving along with the train at the same speed.

Same goes for the air in the train that the fly is “swimming” in.
