A fastening system for track rail includes a molded support block, and a direct fixation fastener positioned upon an upper side of the molded support block. The direct fixation fastener includes a metallic frame and a non-metallic overmolded jacket. Clamping fasteners of the fastening system are structured to engage with retention elements integrally molded in a concrete matrix material of the molded support block to clamp the direct fixation fastener to the upper side within a range of lateral positions.

A ballastless track system comprises a base; a track slab arranged above the base; a poured-field layer arranged between the base and the track slab, the poured-field layer being formed by filling self-compacting concrete, emulsified asphalt cement mortar or resin mortar, and the inside of the poured-field layer being of a steel bar structure; a connecting piece, the first end of the connecting piece extending into the track slab, and the second end of the connecting piece extending into the poured-field layer; and two rows of rail-seat arranged on the track slab in parallel; and rails arranged on the rail-seat. The ballastless track system is high in reliability, good in durability, and easy in construction and maintenance.

A system for detecting and pre-warning railway roadbed deformation includes: a control box and an optical fiber-pressure sensor group. The optical fiber-pressure sensor group is formed by disposing a plurality of optical fiber-pressure sensors into a cuboid shape, and is buried in the railway roadbed for detecting magnitude of roadbed deformation in each direction. The direction of the deformation can be acknowledged easily, allowing the staff to eliminate potential risks purposefully. A time series prediction algorithm is performed to forecast a trend of the roadbed deformation in each direction, such that the staff may purposefully overhaul and correct the tracks where the roadbed is deformed excessively. At the same time, the staff may overhaul the track before the magnitude of the roadbed deformation reaches a predetermined value. Potential safety hazards may be eliminated in advance, ensuring the safety for the operation of the railroad.

A device for transferring an infrastructure component pre-positioned on a ground, particularly a track support plate, into a target arrangement, comprises a connecting means for fastening the device to a mating connecting means of the infrastructure component, a ground contact means for support on the ground, an actuating device for absorbing a first rotational movement about a first axis of rotation, and a transmission device for converting the first rotational movement into a first transferring movement of the ground contact means relative to the infrastructure component with a translatory movement component orientated perpendicular to a first axis of rotation. A combination and a system comprising at least one such device. A method for transferring an infrastructure component.

A turnout arrangement of a slab track with a ballastless superstructure for forming a main track (1) and a branch track (2) which branches off from the main track for railway traffic has a plurality of prefabricated turnout bases (3) of untensioned reinforced concrete, a casting compound (5), which is cast and hardened between the aligned turnout bases and the ground (4), a plurality of fastening areas (6) which are rail support points (7) provided on the turnout bases for the rail fastening of the main track, the branch track, and further turnout components. The turnout bases of the turnout arrangement are elastically supported, and each turnout base is provided with a positive-locking arrangement for positively holding the turnout base horizontally with respect to the casting compound. An elastic layer (8) is provided between a projection (13) of an element of the positive-locking arrangement and the turnout base.
