WebWork is now underway to electrify and modernise around 170 km of track, which mostly consists of installing overhead line equipment to power our new trains. What is Overhead … WebNorth of there and most of the rest of the electrified network (much of it isn’t electrified at all) use overhead power. 25kv AC from the wires using a pantograph. Sone trains just operate in one area so just have either the shoes or the pantograph. Some operate in both so have both. AC is more efficient, trains are more powerful on overhead ...

Train Facts 15. 17 Upgrading crossings. An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is overhead line. It is known variously as overhead catenary, overhead contact line … See more Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors … See more In the Soviet Union the following types of wires/cables were used. For the contact wire, cold drawn solid copper was used to ensure good conductivity. The wire is not round but has grooves at the sides to allow the hangers to attach to it. Sizes were (in cross … See more Given limited clearance such as in tunnels, the overhead wire may be replaced by a rigid overhead rail. An early example was in the tunnels of the Baltimore Belt Line, where a Π section bar (fabricated from three strips of iron and mounted on wood) was used, with the … See more To achieve good high-speed current collection, it is necessary to keep the contact wire geometry within defined limits. This is usually achieved by supporting the contact wire from a second wire known as the messenger wire (in the US & Canada) or … See more Catenary wires are kept in mechanical tension because the pantograph causes mechanical oscillations in the wire. The waves must travel faster than the train to avoid producing See more Lines are divided into sections to limit the scope of an outage and to allow maintenance. Section break See more Trams draw their power from a single overhead wire at about 500 to 750 V.
