Roll2Rail was one of the lighthouse projects of Shift2Rail, supported by the Horizon 2020 programme of the European Commission (2015-2017).

Roll2Rail was one of the lighthouse projects of Shift2Rail, supported by the Horizon 2020 programme of the European Commission. The Roll2Rail project focussed on rolling stock and aimed to develop key technologies as part of a longer term strategy to revolutionise the rolling stock for the future.

Roll2Rail aimed to impact the performance of railways at the system level by introducing breakthrough technologies that should revolutionise the train concept for the future. The project expected innovations in 8 different areas such as traction and power electronics, train communications, car bodyshell, running gear technologies, brakes, train interiors, noise and vibration and energy performance.

Our work was based in WP7 Noise in which we played a leading role. To reduce the overall noise from railways in Europe and allow for better designs there is a specific need to further develop an assessment procedure that can separate track noise from vehicle noise. One example of rolling stock legislation is the TSI NOISE where pass-by levels are often dominated by rolling noise for which track noise contribution plays an important role and track parameters are key factors.

The work aimed to develop a practical and reliable hybrid method for the separation of rolling stock noise from track noise during vehicle pass-by. Extensive validation tests were conducted near Munich in Germany including a microphone array developed at ISVR.
