Two Trains and a fly

Two trains are 200 km apart, and traveling towards each other at 50 km/hour each.
From one train a fly takes off, flying straight above the rails to the other train at the speed of 75 km/hour, bounces off it and flies back to the first train.

"This is repeated till the trains crash together and the fly is smashed."

What distance is the fly able to fly until its meet its tragic end?

Watch this space for answer in a week.
