It sounded as if someone was saying \"SSSSHHHHHHH\" very loudly as the fireball moved through the sky. There was no other sound while it was moving and there was no sound when it disintegrated.

Remarks
The train was a glowing orange that tapered to a point. When it disintegrated, the trail slowly fell. It looked like after a firework has gone off - and the embers are slowing falling back toward the ground - except the trail did not fall that far and it all disappeared at the exact same time.
