Operation of the overhead conductor rails at Shaw's Cove Railroad Bridge in Connecticut. In a movable bridge that uses a rigid overhead rail, there is a need to transition from the catenary wire system into an overhead conductor rail at the bridge portal (the last traction current pylon before the movable bridge).
On most systems, the conductor rail is placed on the sleeper ends outside the running rails, but in some systems a central conductor rail is used. The conductor rail is supported on ceramic insulators (known as "pots"), at top contact or insulated brackets, at bottom contact, typically at intervals of around 10 feet (3.0 m).

Patented track rails are engineered specifically for overhead cranes and monorails. [9] [10] Unlike a symmetrical structural rail, the material in a patented track rail is placed where it is most effective allowing for a significant reduction in weight. The rails are engineered to be twice as strong as typical A-36 structural beams and have a ...
All South Korean systems use overhead wires (or rigid conductors), as do most modern mainland Chinese metros. In Europe all significant Spanish systems now have overhead power supply. Modern Latin America urban rail also uses overhead wires, though with some important exceptions. Special group of bottom power supplied railways are rubber-tyred ...

An overhead crane, featuring runways, bridge, and hoist in a traditional industrial environment. Overhead crane at the Skanska precast concrete factory in Hjärup, Sweden. Gantry-style overhead cranes of the Hainaut quarry in Soignies, Belgium. An overhead crane, commonly called a bridge crane, is a type of crane found in
Conductors: overhead line or; conductor rail, usually a third rail to one side of the running rails. Conductor rail can be: top contact: oldest, least safe, most affected by ice, snow, rain and leaves. Protection boards are installed on most top contact systems, which increases safety and reduces these affections.
Overhead lines or overhead wires are used to transmit electrical energy to trams, trolleybuses or trains. Overhead line is designed on the principle of one or more overhead wires situated over rail tracks. Feeder stations at regular intervals along the overhead line supply power from the high-voltage grid.
