NIGHT LIGHTS FOR PULLMAN CARS The Pullman Company has been experimenting for sometime with various lighting arrangements designed to pro-vide suitable illumination for the aisles of sleeping carsafter the passengers have retired. A satisfactory installa-tion has recentl)- been developed and is now being appliedto all new cars built and also to cars which pass throughthe shops for repairs. It may be of interest to give a few details of the numerousinstallations which were tried before a method of lightins:. Atrnngement of Aisle Liglit Under tlie Ber-th was evolved that would fulfill all the reciuirements. In oneof the experiments a light was placed at the bulkheads at theends of the aisles and shaded with an amber glass, with aview to providing a non-glaring light to illuminate the aisleat night. This was found to be unsatisfactory as it lightedthe end sections to some extent. An attempt to secure thesame results by dimming the ceiling lights also proved afailure. An installation with lights under the seat ends wastried, but the light was found to be annoying to the occupantsof the lower berths opposite the fixtures. This objectionhas now jjcen overcome by shading the light with a greenglass. The lighting arrangement wliich has been adopted forilluminating the aisles consists of IS watt, 32 volt, type Stungsten lamps in receptacles placed under the ends of al-ternate seats. As the ends of the aisle are illuminated by thelights at the bulkheads it is not ne
