A railway or tramway track includes track rails arranged on a foundation surface. Noise and vibration reduction elements are arranged between the track rails and outward of the track rails. The noise and vibration reduction elements include at least one non-humic layer that absorbs water, reduces rate of flow and outflow of the water, and allows evaporation of the water.

An inspection device includes: an obtainer that obtains at least one captured image of a plurality of sound insulation plates; a deriver that derives a displacement of each of the plurality of sound insulation plates in the image; and an extractor that, based on the displacements of the plurality of sound insulation plates, extracts, from the plurality of sound insulation plates, a sound insulation plate of interest that moves differently from another sound insulation plate included in the plurality of sound insulation plates.

A transport vehicle is provided. The transport vehicle includes a front driving device including front wheels, a front drive shaft transmitting a driving force to the front wheels, and a front vibration reduction device, and a rear driving device including rear wheels, a rear drive shaft transmitting a driving force to the rear wheels, and a rear vibration reduction device, wherein, when the transport vehicle moves in a straight section, the front vibration reduction device and the rear vibration reduction device are coupled to each other, and when the transport vehicle moves in a corner section, the front vibration reduction device and the rear vibration reduction device are separated from each other.

A flexible rail boot designed to encase a rail. The rail boot includes antenna and a truss, allowing for the storage and release of energy, locking the rail boot in place under the head of the rail after installation. The flexible rail boot may include a corrugated inner surface along the bottom of the base of the rail, compressing and deflecting energy from a train as well as allowing for the passage of water and debris.

A damping arrangement for tracks to be travelled over by rail vehicles having flanged wheels, including a) a rail, and b) an outer lateral profile of elastomer material which bears on the outer side of the rail at least in a region of a lateral outer rail head flank and in a region of an outer rail head underside, wherein the outer lateral profile has, in the region of the outer rail head underside and in the region of the lateral outer rail head flank, close to the rail, a soft region which is elastically resilient with respect to the rail head, and, in the region of the lateral outer rail head flank, remote from the rail, a substantially non-elastic hard region.

A rail tie pad for use with a cast rail tie. The rail tie pad may be flexible, polymeric body having first and second opposite sides and, when viewed in cross-section, includes an upper surface and a lower surface defining a first vertical thickness and including a plurality of undulations with alternating concave portions and convex portions. The rail tie pad further includes a pair of side anchor portions respectively disposed at the first and second opposite sides of the pad, each including at least one anchor projection for embedment within the side portions of a cast rail tie. In this manner, the anchor portions of the rail tie pad are embedded within, and fixably secure, the sides of the rail tie pad to the cast rail tie to mitigate or prevent separation of the rail tie pad from the rail tie during transport and/or positioning of the rail tie during installation.

A clip assembly for securing first and second tuned mass dampers to respective first and second sides of a rail. The clip assembly includes a bar element having a connector portion extending between first and second ends thereof and formed to be positioned in a predetermined location relative to the rail at least partially under a foot of the rail, and a first clamping arm connected with the connector portion at the first end of the connector portion, the first clamping arm being formed to engage the first tuned mass damper. The bar element also includes a linkage section located at the second end of the connector portion. The clip assembly includes a second clamping arm extending between upper and lower ends thereof, the lower end comprising a locking portion securable to the linkage section, and the upper end being formed for engagement with the second tuned mass damper.

A tuned mass damper for damping airborne vibrations at one or more rail frequencies from a rail generated by movement of wheels over the rail. The tuned mass damper includes one or more damper elements including a damper element material, and a body element including a body material. The damper elements are at least partially embedded in the body element. The body element has inner and lower exterior surfaces formed to fit within first and second pockets on opposite first and second sides of the rail defined by a web portion and a foot. The damper element material and the body material are selected and formed so that the tuned mass damper vibrates in response to movement of the wheels over the rail at one or more damper frequencies that at least partially interferes with the rail frequencies.

The present invention concerns a gabion (1) comprising: a cage (10) basically box-shaped, made up of a bottom (11), two frontal walls (12, 13) and two side walls (14, 15). That bottom, frontal and side walls are all formed from meshes respectively (11.1, 12.1, 13.1, 14.1, 15.1) that are fixed to each other; two compartmenting partitions (20, 30), that each connect the side walls to one other within the interior of the cage so that the internal volume (V10) of the cage is divided into: two frontal compartments (C1, C2) that are each filled with a filler material (70) made up of aggregate that cannot pass through the respective meshes of the bottom, the frontal or the side walls, nor through the compartmenting partitions in such a way that it is retained within those frontal compartments, and an intermediate compartment (C3), bounded by the compartmenting partitions and which is able to receive a granular acoustic insulation material (2); and at least one lifting partition (50, 60), that fixedly connects the frontal walls (12, 13) to each other within the cage extending through each of the frontal compartments and the intermediate compartment, which, opposite the bottom (11), is provided with at least one grab handle (51, 61), and which, for the part that is set out in the intermediate compartment, is suited to allowing the acoustic insulation material granules (2) to pass through it in such a way that the acoustic insulation material may spread freely, within the intermediate compartment, on either side of the lifting partition.

A system for actively attenuating acoustic vibrations of a rail for rail traffic is provided including at least one sensor for detecting at least a vertical acoustic vibration of the rail, at least one actuator for exciting at least a vertical counter-vibration of the rail and at least one control unit communicatively connected to the at least one sensor and the at least one actuator for controlling the at least one actuator depending on the vibration detected by the sensor, the counter-vibration being adapted to destructively interfere with the detected vibration, and the at least one actuator being mechanically coupled to the rail and to a carrier element supporting the rail. Also provided is a carrier element for the system and a method for actively attenuating acoustic vibrations of a rail for rail traffic.
