This 1942 dated signal light is from the Deutsches Reichsbahn. Lamp is in excellent condition and could easily be used today. Powered by kerosene, this lamp could be used indefinitely due to the engineering of the Germans! The lamp is nicely maker marked and dated 1942 and "DR" for the Deutsches Reichsbahn.  Also with the lamp, is the original red lens cover. This lamp was used in the guards station telling trains to proceed or stop, depending what color lens they were flashing. There is also a light indicator on the reverse of the lamp telling the handler that the light was projecting. Lantern is roughly 18 inches in height and in excellent condition. When Hitler and the NSDAP gained power in January 1933 the German railway system was maintained and administered by two civilian organizations, the DR, Deutsches Reichsbahn, (German National Railway), and the, DR-G, Deutsches Reichsbahn-Gesellschaft, (German National Railway-Corporation), which were overseen by the national government. Both the DR, and the DR-G were uniformed organizations responsible for all the railways within Greater Germany and eventually in the occupied areas. In February 1937 in a restructuring of the national railways the DR-G was absorbed into the DR.
