A CURTAIN OF AIR
Air currents take the place of the door between the kitchen and diner on the latest streamline train in the United States, thus eliminating cooking odours, protecting passengers from heat, and giving waiters quick access. Air is pumped through, slits on opposite sides of the door frame and deflected towards the kitchen, forming an invisible curtain through which fumes cannot pass. An overhead exhaust ventilator sucks up fumes checked by the air curtain.
