Abstract
A supporting system supporting a rail of a rail track above a substrate. The system includes a support having an tipper surface for supporting the rail and a lower surface facing the substrate. The support is maintained between the lower surface and the substrate and, in response to separation of the rail and the substrate, movement of the rail towards the substrate is inhibited.
