In order to reduce the lateral force between wheel and rail during curve negotiation, the possibility of railway trucks with actively steered wheelset has been investigated. This paper deals with a basic study about the active steering trucks, which employs force control that is proportional to bogie angle. Three different types of steering control are compared under the condition of expected operation speeds of +45km/h over the regulation, and the control type that steers only leading axles in each truck is recognized to be appropriate. Here, tilting trains with the tilt angle of 7 degrees are premised. The wheel lateral forces are compared with those of usual tilting trains without steering mechanism running at speed of +25km/h. Simulation results show that the wheel lateral force of the leading axle in the active steering truck is smaller than that of other trucks. The active steering truck shows also its superiority over the conventional trucks on the axle lateral force under the practical curving condition with truck irregularities.
