A self steering railway bogie configured to run on a railway track having two opposed rails defining a track centerline therebetween. The bogie has a forward end and a rearward end and includes a pair of axle sets having a forward axle set and a rearward axle set disposed at the forward end and at the rearward end of the bogie, respectively. Each axle set has a pair of independently rotating wheels defining wheel axes, each wheel being disposed at a respective side of a corresponding axle set and further having a rail-engaging profile such that a wheel of each axle set moving away from the track centerline rises and a wheel of each axle set moving toward the track centerline falls. The axle sets are configured such that, when the bogie enters and traverses a curved section of track defining a center of curvature, the wheels of the forward axle set move away from the center of curvature and the wheels of the rearward axle set move toward the center of curvature whereby the forward axle set and the rearward axle set become inclined at different inclination angles with respect to a horizontal plane as a function of a curvature of the track. The bogie further includes a mechanism arranged and constructed for steering the bogie in response to the inclination angles of the axle sets such that the wheel axes converge on the center of curvature of the curved section of track.
