According to the principle of inertia, when the train is moving at a constant velocity, any object on the train (including you) is also moving at that velocity. Therefore, if you jump straight up, you are still moving at the same velocity as the train. This means that you will land at the same position from which you jumped, i.e. your original position on the train.
