Abstract: A ground stabilisation system is used for stabilising a subgrade region which includes a peat layer under a railway having rails supported across rail ties on a ballast layer over the subgrade region. The system uses a plurality of drain members submerged in an upright orientation within the peat layer of the subgrade region in which each drain member has a hollow interior and a plurality of openings therein which allow communication of fluid from the peat layer surrounding the drain member into the hollow interior of the drain member so as to be arranged to reduce fluid pressure in the peat layer when the peat layer undergoes dynamic loading from a passing train. Each drain member is a semi-rigid pipe having an axial stiffness greater than a dynamic stiffness of the peat layer to reduce loading on the peat layer under dynamic loading from a passing train.

Abstract: The sleeper block unit (1) for railway track systems consists of a sleeper block (2) and of a sleeper shoe (3) that partly surrounds the sleeper block (2). The sleeper block (2) has a head portion (4) and a base portion (6), the head portion (4) extending beyond the base portion (6) in length and in width, thus forming a step (10). At the upper edge of the sleeper shoe (3), a surrounding, upwardly and outwardly extending sealing lip (14) that lies against the step (10) is arranged. As a result, during vertical movements of the sleeper block (2) in the sleeper shoe (3), the sealing lip (14) is deformed substantially vertically in the elastic range rather than rubbing against an outer wall of the sleeper block as in known sleeper block units. In this manner the sealing lip is subject to reduced wear so that the sealing effect is maintained for a longer period and the sleeper block unit (1) has a longer lifetime.
