railroad Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a pre ...

traction current A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), ele ...

. In Germany, traction current lines with two systems (4 conductor cables) typically have a single level arrangement of the conductor cables. For traction current lines with four systems (8 conductor cables), the two-level arrangement (4 conductor cables on each crossbar) is frequently used, except for traction current lines supplying high-speed railway lines are used. For these lines a three-level arrangement is used, in which the lowest cross bar has four conductor cables and each of the two highest cross bars have two conductor cables. The three-level arrangement is also used for traction current pylons with 6 electric circuits (12 conductor cables). For the supply of rapid-transit railways operated with alternating current, some

overhead line An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipmen ...

pylons have cross bars for traction current lines above the contact wire. Other pylons carry electric circuits for traction current and also for three-phase alternating current.
