A steering bogey for a railway vehicle, suitable for use with a railway with static points, comprises a bogie chassis 6 pivotable about a vertical axis. The bogey or truck has four wheels 5, each of which is also pivotable about a vertical axis. The steering direction of the wheels may be controlled by linear actuators 2 and linkages 3, and the control may include torque feedback. The steering direction of the wheels may alternatively be provided by four respective steering direct drive motors with servo positioning control. Also described is a railway with static points. The points have flat areas at the regions of rail divergence so that flanges of vehicle wheels support the wheels at those regions. The flat areas are provided by rail head tapering downwardly at each end with a lower base rising to provide the contact with wheel flanges. Also described is a system wherein the points have, at the regions of divergence, two parallel pairs of rail, the vehicles having two corresponding sets of wheels. At the divergence regions with one wheel set engaging the rails of one pain, the other wheel set is lowered from an initial raised position to engage the other rail pair and the first set is then raised.
