(100, 100a, 100b, 100c, 100d, 800, 1000, 1100) upon which a plurality of rails (190) can be supported, wobei a slab (110,1010) of the rail support arrangement is mounted to a bedding layer provided directly onto an installation area of compacted ground.

A module (100) for a system for the laying of underground and railroad and tram lines both in tunnel and on the surface, in particular railroad and tram lines, comprising a supporting slab (101) for the tracks (6), with substantially parallelepiped shape, the slab having at least four peripheral housings (1), passing from the extrados to the intrados and suitable to house respective adjustable levelling devices (120).

Method of design and manufacturing concrete structures subjected to relevant cyclic loads along their service lives, as wind towers, and a fatigue testing machine. The method consists on the design of concrete structures conditioned by cyclic loads considering a fatigue strength value specified by the project as one of the main design parameters, which will be verified during the manufacturing phase as one of the control parameters of the quality assurance plan by performing fatigue strength test on concrete samples representative of the concrete structural elements produced on said manufacturing phase. The method allows to decouple the concrete fatigue strength from the compressive strength of the material, which is why includes a verification of the fatigue strength as a part of a quality assurance plan of production according to a new developed procedure.

This method for manufacturing a railway track support comprising a plurality of prefabricated elements (28) comprises the following successive steps: providing, in a production zone (16) for prefabricated elements (28) located near an installation zone (14), a movable insertion machine (52) configured to arrange at least one insert (34) in a fresh concrete block, the production zone being separate from the installation zone; pouring and shaping fresh concrete in order to form individual fresh concrete blocks having predetermined dimensions; arranging at least one insert in each fresh concrete block using the movable insertion machine (52); drying the fresh concrete blocks to obtain the prefabricated elements (28).

The invention relates in particular to a guided transport track section intended to be fixed to a ballastless track formation (15), characterised in that said section comprises: a track panel (20) comprising two stringers (21, 22) and at least one structure transverse to the stringers (23, 24), each stringer (21, 22) comprising an upper longitudinal groove (25) for receiving a rail; a plurality of panel supports (31, 32, 33, 34), each support comprising at least one stud (35) for fastening to the track formation, a cradle (37) for supporting a stringer (22) that is mounted so as to be movable vertically in said stud (35), and means for vertical movement of said cradle (37) relative to said stud (35) so that the height of the panel (20) relative to said track formation (15) can be adjusted, and the superelevation of the track section thus formed can be defined by means of coordinated adjustment of the various cradles (37).

Track and more particularly slabs (1) for a light railway track in which the slab comprises a convex end (2) and a concave end (3) which are generally concentric and reciprocal to each other such that in use the convex end of one slab and engage the concave end of another slab with the respective slabs at an angle to each other. The slabs are secured together to provided straight and curved sections with a modular slab shape and allowing other features for monitoring and/or improved operation.

A module (100) for a system for the laying of underground and railroad and tram lines both in tunnel and on the surface, in particular railroad and tram lines, comprising a supporting slab (101) for the tracks (6), with substantially parallelepiped shape, the slab having at least four peripheral housings (1), passing from the extrados to the intrados and suitable to house respective adjustable levelling devices (120).

A support (32) adapted to be used in place of ballast in supporting a rail support member (31) of a rail track comprises a body (50). The body (50) includes a lower face (70) for resting on a support surface, and an upper surface (71) for supporting the rail support member (31).

A bonded fastener for a railway rail comprising: top and bottom generally horizontal plates bonded and separated by an insulating material wherein the top plate defines a rail bed; a plurality of clip housings wherein each clip housing houses part of a hold-down clip for attaching the rail to the bonded fastener; a plurality of anchor assembly areas wherein each anchor assembly area defines an opening through the bonded fastener for receiving an attachment device for attaching the fastener to a supporting surface; and one or more generally vertical barriers comprising part of the bonded fastener. Further, a first generally horizontal barrier may extend from the bonded fastener underneath each of the clip housings, and a second generally horizontal barrier may extend from the rail bed underneath the rail on each side of the bonded fastener.
