you see it moving away from you at 500 mph
a bystander on the ground sees it moving at 1000mph
you see it moving away from you at 500 mph
a bystander on the ground sees it standing still (and falling to the ground under gravity when it then moves forward with the train)

Some people seem to have trouble reading questions.
You'll see it moving away at 500mph. A bystander will see it moving at about 999.99999mph. The velocity of the bullet to a bystander on the ground will be a tiny bit less than the sum of the velocities because of general relativity.

If you shoot forward, the speed of the bullet will be the sum of the muzzle velocity and 500mph. If you shoot backward, the speed of the bullet will be the muzzle velocity subtracted from 500mph. This is assuming that there is no air, which wouldn't make TOO much of a difference.

Ok, you shoot forward. Since the gun is already moving along at 500 mph, the bullet coming out would go ahead of the train, for a while, before it slowly drops to the ground, but it would go ahead of the train.
If you shoot back, the bullet would also slowly drop to the ground.
Both times, the train would keep going.
