Equipped with special Allied Full Cushion high-speed swing-motion trucks, Pullman troop sleepers were designed to be fully interchangeable with all other passenger equipment. The units came equipped with end doors similar to those found on standard railway cars, but had no vestibules. Loading and unloading of passengers was accomplished via wide doors positioned on each side at the center of the cars with built-in trap doors and steps. Light and ventilation was provided by ten window units mounted on each side, each equipped with rolling black out shades and wire mesh screens.
