Powerlines electrifies Trolleybus in Switzerland

Powerlines electrifies Trolleybus in Switzerland :The Powerlines Group has been awarded a contract in the Swiss city of Winterthur via its German subsidiary SPL Powerlines Germany. The city will be conducting large-scale renovation work on its trolleybus network through to 2020. The existing network accommodates 1,869,574 scheduled kilometers and some parts are to be newly regulated. On other sections of the routes the overhead line system is to be rebuilt.

Renovation is to be carried out on line 1 (Oberwinterthur-Töss), line 2 (Wülfingen-Seen) and line 3 (Rosenberg-Seen). Alongside these three lines Powerlines will also be responsible for electrifying the newly built depot in Grüzefeld, where transverse wires are to be remounted, electric track switches installed and the contact wires retensioned. A total of 28 km of contact wire is to be installed and 47 km regulated. The flat catenary contact line system (contact wire Type Ri 107) will require an operational voltage of 600 V DC. As well as installing the catenary system, SPL Powerlines Germany has also been charged with installation of the power feed points, and with the integration of mechanical and electrical overhead line switches. Gerhard Ehringer, CEO of the Powerlines Group explains: ‘Trolleybuses are a traditional feature in Winterthur and have been an integral part of the local public transport system for many years. Powerlines is one of only a handful of companies in Europe able to plan and implement catenary systems for trolleybuses. I’m delighted we have been given the privilege of contributing our know-how in this field in Winterthur. It is also an important step towards establishing the Powerlines Group within the Swiss market’.

Trolleybuses in Europe
In built-up municipal areas electrically powered trackless trolleybuses provide a greater degree of flexibility than trams and underground trains, and also offer a bonus of environmental friendliness compared to diesel powered city buses. In the 1950s and 1960s trolleybuses were a common feature of local transport, but have become much rarer over the last few years. In Germany and Austria they are only in operation in five cities: Solingen, Eberswalde, Esslingen am Neckar, Linz and
Salzburg. In contrast, in Switzerland alone trolleybuses are integral features of the public transport networks of 12 cities and are a popular means of transport in 16 cities in Italy. However, there is only a thin scattering of trolleybuses in the remainder of western and northern Europe.
