Abstract
A steerable truck for a railway car is provided with a truck frame that is steered so as to be aligned with the tangential direction of a curved track by controlling only the steering angle of a rear wheelset. During travel along a curved track, the steering angle, which is the angle in a horizontal plane of the centerline of the rear wheelset with respect to an imaginary straight line connecting the center of the truck frame and the center of the curved track, is larger than the steering angle which is the angle formed between the imaginary straight line and the centerline of the front wheelset. As a result, a steerable truck for a railway car which has excellent ability to travel along a curve and which can be actually realized simply and at a low cost is provided.
