LGV Sud-Est
Next, the wheel-rail interface was attended to. Axle bearings were unmodified items, broken in for 10,000 km in revenue service on the LGV Sud-Est. Yaw dampers were stiffened, and doubled up on each side for a total of four yaw dampers on each truck, for redundancy in case of a high-speed failure. As a result of earlier testing and computer simulations, transverse dampers were stiffened on the power trucks.
