Bahnstromversorgung mittels 3. Schiene: U-Bahn Wien

Vienna U-Bahn

A bottom-contact third rail

The underground with the longest planning history

The city on the Danube holds the record for the longest planning history for its underground network – the plans go all the way back to the 1840s. However, it was not until 1968, that the construction of the Vienna U-Bahn was given the go-ahead by the city council. The U-Bahn officially opened in 1978, though trains had been running on the route between Heiligenstadt and Friedensbrücke since 1976.

Due to the complex planning history of the U-Bahn network, parts of it are actually much older – it incorporates the light rail system built by Otto Wagner in 1898, which was actually a standard-gage railway for steam engines. Today, the five lines measuring a total of 78.5 km in length are used by around 1.4 million passengers per day.

Our solutions

Since 1987, we have provided the Vienna U-Bahn network with around 100 km of cover profiles and 25,000 glass fiber-reinforced conductor rail carriers.

Good reasons to opt for our traction power supply systems

Our conductor rail cover profiles are

  • UV-stabilized, making them ideal for outdoor use,
  • highly resistant to a range of chemicals,
  • extremely impact-resistant and can take the weight of a person, and
  • are tracking-resistant, reliable and insulating.
  • Quick to set up and requiring little maintenance, they are suitable for installation in a wide range of situations.

Our carrier systems consist of

  • shock-resistant, chemical-resistant and corrosion-free materials with a high level of durability.
  • They are also less likely to break than ceramic or cast resin insulators and
  • have much better electrical properties than steel beams
  • They have been tried and tested in various climates, are easy to install and require little maintenance.
