EHIGHWAY. In the past few days, tests were made with the trolleybuses in column runs. Up to six vehicles were used and different aspects of the interaction with the infrastructure were investigated at varying distances between the trucks.

Among other things, the vibration behavior of the overhead contact line was measured in order to see whether, for example the distance of the trucks has an influence on the quality of the pantograph run. But also the energy demand of the trucks, the behavior of the substations under high loads – e.g. by simultaneous acceleration of the trucks – as well as the electrotechnical control mechanisms in case of overload were put to the test.
