A little info on the dagger that might help in further research. The German government established the Bahnschutz, (railroad special protection force). The personnel were drawn from the railroad employees and were resopnsible for the protection of the railroads in time of war and civil disorder. The units were armed with rifles and machine guns and were charged with maintining law and order on railway property and in preventing larceny, espionage and sabotage.

There was also a distinctive called the Reichsbahn Wasserschutz Polizei (Railway Water Protection Police). Their mission was to provide security of the railroad facilities associated with harbors, canals and inland waterways. Their distinctive dagger was adoped in 1935 for the leaders of the Bahnschutzpolizei. It was nearly identical to the standard Army dagger. In 1938 a distinctive dagger was authorized which was different from the Army Dagger. On the hilt crossguard appeared the winged railway wheel insignia of the National Railway System. (looks very much like the Goodyear and the Ohio State Patrol winged wheel). If you come across a winged wheel proof on a luger this is probably what it would look like, if any exist. Hope this has been of some help. Info above is largely from Ltc Thomas M. Johnson's book, Collecting the Edged Weapons of the Third Reich, Volume 1.
