Ballast pick-up at high-speed railway route

In the course of the launch of the new route Vienna – St. Pölten the measurement parameters were comprehensively examined during specifically performed high-speed test runs. A partial aspect of these test runs was the study of potential occurrence of ballast pick-up at the new high-speed railway route in the area of Tullnerfeld.

The objective of the investigation was to identify the influence of ballast height in sleeper bays on ballast movements in train passages in order to prevent the appearance of ballast pick-up from the infrastructure side. Three 30 m long test sections with different ballast depths were established and marked with colours in order to be able to document any movements of the ballast grains.
