Oberleitungsschiene

Oberleitungsschiene is a German term that translates to "overhead conductor rail" or "contact rail" in English. It refers to a type of current collection system used primarily in electric railways and trams. Unlike pantographs, which collect current from an overhead wire, the Oberleitungsschiene is a rigid or semi-rigid bar that runs parallel to the track.

This system is typically employed in areas where a traditional overhead catenary system might be impractical or aesthetically undesirable. Examples include tunnels, depots, or sections of track with low bridges or other height restrictions. The vehicle is equipped with a shoe or collector that slides along the surface of the Oberleitungsschiene, drawing electrical power to operate the motor.

There are several types of Oberleitungsschiene systems, varying in their design and method of current transfer. Some are enclosed to protect against environmental factors and prevent accidental contact, while others are more exposed. The choice of system depends on factors such as voltage, current requirements, speed of operation, and safety considerations. The Oberleitungsschiene is an effective solution for providing continuous power supply in specific urban and infrastructural environments.
