The mechanical tension in the wire was increased to 40 kN from the standard 25 kN. The speed of the transverse wave induced in the overhead wire by the train's pantograph was thus increased to , providing a margin of safety beyond the train's maximum speed. Several measurement stations were installed along the test tracks to monitor stresses in the track and ballast, noise, aerodynamic effects, and catenary dynamics.
The tension in the wire was raised from 25 kN to 40 kN. This adjustment led to a higher wave speed induced by the train's pantograph, ensuring safety beyond the maximum train speed. Various measurement points were placed along the test tracks to monitor track stress, noise levels, aerodynamic effects, and catenary dynamics.
