The standard transport vehicle used by the Haven City military. It commonly is used to drop soldiers into combat zones or transport people from Haven to far away locations. To use it, passengers are required to carry an air train Security Pass. An air train can be found at the Port and apparently can be used by anyone as long as they have the security pass.
It resembles a large blocky vehicle, with two pairs of wings on the side, engine boosters and some precursor writing. It only has windows on the front size, which is slanted for better aerodynamics. It has a hatch which opens upwards on the back of the vehicle. In Jak II the air train is painted a Krimzon Guard red, while in Jak 3 it's a Freedom League blue.
