DOUBLE-LEVEL RAILROAD CAR HAVING A FLAT CENTER SILL A railroad car having an upper and lower level is disclosed. The lower level is positioned above a flat center sill extending along the length of the car and supported above the axles of the wheels at either end of the car. The upper level is positioned vertically above the lower level. Each of the levels includes doorways opening to the floor region of the respective levels. Having a doorway at each level permits a freer flow of passenger and railroad service personnel traffic between railroad cars. The upper level includes an observation deck having an integral window member which has a substantially vertical portion, a curved portion, and a generally horizontal portion. The shape of the duct system ensures that forced air is evenly distributed along the car.
