It was part of the Volkspolizei and dealt with all modes of transit but primarily with trains and railroads.
It consisted of approximately 8,500 men, that were organized from a national level and at district level with each Deutsche Reichsbahn district; Berlin, Cottbus, Dresden, Erfurt, Greifswald, Halle, Magdeburg and Schwerin.
They were organized into sixteen companies and equipped with small arms and RPG-7 shoulder-fired antitank grenade launchers.
The Transportpolizei supervised all larger train stations and controlled the travellers, particularly at the border with West Germany, and directed traffic.
Starting from March 1957 it was transferred to the Volkspolizei, whose supervising inspector was Otto Auerswald.
