Abstract
A height compensation device for a railway truck having at least two pairs of rail engaging support wheels. The height compensation device is secured at opposed ends of a truck bolster and compensates for car body height loss after the wheels are re-profiled. The compensation device comprises a bearing element having a top support surface on which the car body rests. A displaceable height adjustment plate having one or more shim sections of different thicknesses is provided with one of the sections being disposed between the bearing element and the truck bolster by lifting the car body off the bearing element whereby to dispose the top support surface of the bearing element at a predetermined desired height above the truck bolster to maintain the car body at a substantially constant height from track level after wheel profiling.
