Abstract: The design of freight running gear has always been a rather steady field. Due to the very demanding tasks as the high ratio between laden and tare weight (up to 5:1), the low cost production and the necessity of easy maintenance procedures, many potential innovations have never found application in the freight wagon market. The design of the Y25 bogie does not allow speed higher than 100 km/h in laden conditions and adequate track friendliness. The paper introduces a new concept of bogie for freight wagons, focusing the attention on the dynamic behaviour of the vehicle and its interaction with the track.
