Pursuit of the Transport Train is the fifth mission of Metal Slug: 1st Mission.
The Hero hops on a handcar and pumps on the lever (by tapping the A button) to reach the POW standing on the blue compartment located at the front of the moving train. The poles and the rail tracks are electrified, so the player must have enough speed to jump over the pole and let the handcar slide through the poles. If the train passes the four poles at the end of the track, the player has no choice than to die.
