ABSTRACT:
In a rail system one or more hydraulic assemblies comprising a movable cylinder (6) with a wheel-engaged rounded head (7) and a fixed piston (4) within the cylinder (6) are located adjacent a running rail (1). When engaged by passing rail wheels (2) the assembly provides pressurized fluid which is fed into a pressure line which leads to means for switching a set of points. Energy is thus extracted from moving rail vehicles and it is unnecessary to provide long-distance power supplies to a set of points.
