Answer 1

Airplanes fly high enough in the sky that the air they face is pretty thin. Trains have to achieve those speeds at ground level, where the air is as dense as it can be, so shapes have to adapt.

Answer 2

Aerodynamics. The more more pointed the nose is, the more effectively it can cut through the air as it moves, and it can move faster without creating as much drag.
