Salzburg AG has ordered another 13 trolleybuses from the Swiss manufacturer Hess for the years 2023 and 2024. When the vehicles that have now been ordered have been delivered, a total of 42 trolleybuses will be on the road in Salzburg.
In 2019, Salzburg AG called off the first 15 vehicles under a framework agreement with Hess. These lightTram 19 DC vehicles were put into operation in 2019 and 2020. In mid-2021 and early 2022, another fourteen identical trolleybuses were delivered from Switzerland to Austria. With the 13 additional trolleybuses ordered these days, the Hess fleet in Salzburg will increase to 42 vehicles in the future.
The articulated buses are 18.7 meters long and can carry up to 155 passengers. The buses have what is known as Hess’ dynamic charging technology and can therefore travel on sections of the route without an overhead line. The traction battery is charged while driving via the power supply of the catenary and can therefore also be used without a catenary.
The background: The overhead line network ends at the Salzburg city limits. Since the ordered trolleybuses also have a battery, they can cover the 4.2 kilometer extension to the Unterbergsbahn without having to install new overhead lines. In battery mode, the range is around ten kilometers with a full load, and up to 35 kilometers when driving empty.
