One of the first construction projects of the Peenemünde experimental institutes was the construction of a factory railway, which was officially commissioned on July 28, 1937, and oriented itself on the only German cities with suburban railway lines: Berlin and Hamburg. It first operated between Zinnowitz, the plant West and the plant East. In the following years, the track network was expanded further, so that other areas of the plant could be reached by train. In the largest stage of expansion, the track network reached a length of 106 km. For passenger transport steam locomotives were initially used with passenger cars and later battery tram trains. On April 15, 1943, the electric train operation began.
The Ost stop was used by the employees of the development plant and residents of the community camp across the street. Since the concentration camp Karlshagen I was located in the immediate vicinity, prisoner transports also ended here. This platform is today the only preserved in the original form, easily accessible breakpoint on the former experimental area. It consists of precast concrete elements and is approx. 180 m long. Since the train door and platform edge were at the same level, it was possible to get in and out of the car comfortably. Electric trains of the ET167 series were used, a modified version of the Berlin S-Bahn trains with overhead line brackets. An original train of the Werkbahn is now on display in the Historisch-Technisches Museum.
