Device and method for building a new ballastway for a rail line
The present invention relates to a method and a device for building a new ballastway for an at least single-track rail line (100, 101) when there is initially no existing track. The new ballastway should have at least one PS layer (2) and one ballast layer (3), and the PS layer (2) is built up on a subgrade (1) and the ballast layer (3) is built up on the PS layer (2) in a continuous working process in a working direction (A). The PS layer (2) is built up by a PS layer-producing unit (20) (PSL unit), and the ballast layer (3) is built up by a ballast bed-producing unit (30), which is operated at a predefined distance behind the PSL unit (20) in relation to the working direction (A) and is equipped with a chain track or caterpillar track (31) for driving on the PS layer (2). The PSL unit (20) and the ballast bed-producing unit (30) are each supplied with the materials (K, S) needed to build up the PS layer (2) and the ballast layer (3) by means of an associated conveying device (12a, 12b) from at least one open-top wagon (10a, 10b), which is operated at a predefined distance in front of the PSL unit (20) in relation to the working direction (A).

Method for covering a ballast bed with foam in a railway track system
A method is provided for foaming a ballast bed of a railway track wherein the railway track comprises sleepers positioned on the ballast bed and rails positioned on the sleepers, wherein the rails are covered at least in a partial area along a region of the ballast bed to be foamed, and a foaming agent is introduced into the ballast bed while the rails are covered, wherein the ballast bed has in a sleeper bay defined by two successive sleepers an upper side facing against the gravitational direction, and the ballast bed is heaped up so that the upper side of the ballast bed reaches at least up to an underneath side of the sleeper facing in the gravitational direction.

Subgrade Peat Stabilisation System for Railway
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.

Shear Resistant Drain System for Improving Weak Foundation Soils
Shear drain devices are used to prepare ground with a weak soil layer to receive a static load, for example a structural foundation or a soil embankment, in which the ground includes a weak soil layer that consists of fine grained soils over a base layer. Each shear drain devices each include an elongate perforated pipe member, a surrounding reinforcement member providing tensile reinforcement and aggregate fill. The ground is prepared by (i) inserting the pipe members and reinforcement members in an upright orientation within the fine grained soils such that fluid in the surrounding soil can readily pass into the pipe members and (ii) subsequently placing the aggregate fill in the pipe members to occupy the hollow interior thereof such that the resulting shear drain devices increase a shear strength of the weak soil layer.
