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 mechanical tension in the wire was raised to 40 kN from the usual 25 kN. The speed of the transverse wave generated by the train's pantograph increased accordingly, offering a safety buffer beyond the maximum train speed. Several monitoring points were placed along the test tracks to observe track and ballast stress levels, noise, aerodynamic impacts, and catenary behavior.
