physics
As for the train accelerating (on level ground) The rate of free fall would not change except it would fall diagonally & may even hit the back end of the train before the floor if the acceleration were too great

physics
I'm no physics scholar, but I'll try... If the train were moving in a straight line at content speed there would be no effect at all on free fall acceleration. As for the rocket, if your in outerspace then there's no gravity to allow for free fall as we know it.
