A majority of the traffic related track deterioration cost originates from freight traffic, With heavier and faster freight trains the maintenance cost Is likely to increase. The present paper focuses on the possibility to improve ride comfort and reduce track forces on standard freight wagons with link suspension. The variation of characteristics in link suspension running gear is considerable and unfavourable conditions leading to hunting are likely to occur. Supported by on-track tests and multibody dynamic simulations it is concluded that the running behaviour of two-axle wagons with UIC double-link suspension as well as wagons with link suspension bogies (G-type) can be improved when the running gear are equipped with supplementary hydraulic dampers.
