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.

The invention relates to a system for securing sleepers in a ballastless track formed by a base plate, sleepers and an interposed elastic intermediate plate, wherein the sleeper body comprises at least one through-hole, and the base plate comprises the corresponding blind holes in which a securing pin is embedded, to which a guide rod that can be inserted in the through-hole is joined, via which the sleeper is secured to the base plate in such a way that no additional pretensioning is added to that caused by the positioning of the sleeper thereon, and only a certain amount of vertical movement is permitted, forming a disassemblable assembly of the securing elements and the sleepers.

The present invention relates to a process and to a system for laying tracks for ballastless railway and tramway lines, both in tunnel and in surface.

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.
