German Unity Transport Project 8

 Nuremberg – Erfurt – Halle/Leipzig – Berlin

Overhead line equipment

The existing overhead line equipment has to be altered and new equipment put in place on the upgraded line, which has a length of 80 km. It is a particular challenge to alter equipment that is in operation, as at the central stations in Nuremberg and Fürth.
Some of the existing overhead line equipment dates back to the 1930s and can no longer cope with high-speed trains or meet maintenance and service requirements.
The new overhead lines are of the standard Re 200 type, which is low-maintenance and can cope with train speeds of up to 200 km/h.

The 5900 line will be a state-of-the-art line and certified as complying with the European standard.

Some of the platforms at the stations are being altered and upgraded. The overhead line systems need to be adapted to allow the construction work, while retaining suitability for passenger trains.

A freight train tunnel is planned to relieve the junction at Fürth station. Another low-maintenance overhead line type is to be used in this freight train tunnel: the overhead conductor rail. The components of the overhead line are fixed to the tunnel's ceiling. The tensioning systems normally required for overhead lines are not required in this case, and there is thus no need to make the tunnel wider, which would be costly.

Traction current equipment

The equipment of DB Energie GmbH supplies the entire length of the 5900 line with the required traction current, which has a frequency of 16 2/3Hz.
Power will be made available along the entire line, and numerous substations and switching stations will be constructed or altered - in Breitengußbach, Großgrundlach and Fürth, for example - in order to supply the overhead line systems. The alteration work on the Fürth switching station is already completed.

The central substation in Stein in Nuremberg is also being altered to meet the increasing line requirements. The lines that supply the freight train tunnel go out from here.
As more railway installations and stations are added and upgraded, the number of systems both supplying them and to be supplied increases.

The number of substations and switching stations and thus the control requirements increase in proportion to that. To enable all of this to be done, the remote control systems on this section of line are being replaced or upgraded. From Vach to Bamberg the remote control systems are all being replaced.
