"The Erfurt-Leipzig/Halle route was used for the record-breaking journey without any modifications. According to Nagl, this shows that infrastructure investments create a solid foundation that lasts for generations. The insights gained will help with future renovations and the development of new high-speed trains.
The ICE test train used was a Velaro Novo test car from Siemens Mobility. Thomas Graetz, Vice President High Speed and Intercity Trains at Siemens, explained that the test runs provided important insights into acoustics, aerodynamics, and handling. The Velaro Novo is set to establish new standards for capacity, economy, and efficiency.
Dr. Hiie-Mai Unger from DB Systemtechnik led the measurements with the special ICE-S test train. This train is equipped with extensive measurement technology and collected data on the interaction between train and track."
