99 percent of the Swiss railway network is electrified. In public transport, economy rhymes with ecology.

The Swiss are world champions in the use of renewable energies for the power supply for the railway network: 75% of the required electricity stems from hydro power stations in the Alps and along the rivers. Many of them belong to the railway company itself.

Furthermore, the modern electric locomotives work as generators during the descent in that they feed electricity back into the railway network on the electrical braking of the traction motor.

In Switzerland, contact lines for railways, trams and trolleybuses are subjected to extreme climatic changes and prove themselves by wind, snow and ice. The renaissance of tram systems in Switzerland – above all in the UNO city Geneva – led to dynamic developments in this means of transport which until recently was dealt with under its value.
