APT-E train preliminary experimental results of an EIT trailer bogie fitted with primary yaw relaxation on the Old Dalby test track (TM-DOS-031)

The preliminary results of a bogie fitted with a primary yaw relaxation device, show that the curving performance is favourable in terms of reducing the quasi-static H force asymmetry between axles. The results show that an ETT bogie fitted with primary traction rods (stiff yaw suspension) was sensitive to wheelset...
