New suspension system for reducing wheel and track wear

Featured story
Liebherr-Transportation Systems, Grand Central Rail (part of Arriva Group) and NewRail (The Centre for Railway Research at Newcastle University) have received funding from RSSB to develop an Active Radial Suspension System (ARSS) to reduce wheel and track wear on the railway.

The Liebherr ARSS uses electro-hydraulic actuators originally developed for aerospace applications to actively steer wheels on rail vehicle bogies, preventing damage to the wheel or rail.

The innovation has the potential to reduce track wear costs for train operators by helping lower the variable usage charge paid to run trains on the UK rail infrastructure.

During the project, the consortium will first model the effects of retrofitting the Liebherr ARSS to an existing UK bogie design – the BT-10. The next step will be installing the model on a trial vehicle for testing in the UK.

The project is expected to complete by the end of 2019.
