Fastening system for fastening a rail
A fastening system for fastening a rail for rolling stocks such as trains, including a base plate, an elastic material and a rigid casing, wherein the base plate is embedded in the elastic material and the elastic material is arranged, at least partially, between the base plate and the rigid casing.
BLOCK BOOT FOR RAILWAY TRACK SYSTEMS
A block boot (1) that has a rectangular ground plan, a bottom (5), and four side walls (2, 3). On the interior of the side walls (2, 3), ribs (10, 15) extending in parallel to the bottom are arranged. At least one of these ribs (10, 15) tapers from the respective side wall (2, 3) toward the interior of the block boot to a free end having a vertex line (24, 25). This block boot is simple to manufacture and offers improved properties with regard to static and dynamic rigidity in operation.
BALLASTED TRACK SYSTEMS WITH RUBBERIZED ASPHALT COATINGS AND RELATED METHODS
An example track system includes: a supporting structure; ballast supported by the supporting structure; a plurality of track ties supported by the ballast; a pair of rails supported by the plurality of track ties; and a layer of rubberized asphalt coating disposed as an interface between the ballast and the supporting structure, the rubberized asphalt coating having bituminous binder, crumb rubber particles, and small gradation hard rock aggregate; wherein resiliency of the layer of rubberized asphalt coating permits particles of the ballast in direct contact with the layer of rubberized asphalt coating to move elastically relative to each other while inhibiting abrasion of adjacent ones of the particles of the ballast against each other and against the supporting structure.
RUBBERIZED ASPHALT COATINGS FOR BALLASTED TRACK AND RELATED SYSTEMS AND METHODS
An example method for forming a track system includes: providing track ties configured to support rails; providing stone ballast configured to support the track ties; and disposing a layer of rubberized asphalt coating between the ballast and the track ties, the rubberized asphalt coating having a bituminous binder, crumb rubber particles, and small gradation stone aggregate; wherein resiliency of the layer of rubberized asphalt coating permits particles of the ballast in direct contact with the layer of rubberized asphalt coating to move elastically relative to the bottom of the tie and to each other while inhibiting abrasion of adjacent ones of the particles of the ballast against each other and against the bottom of the track ties.
AUTOMATED SPRAY SYSTEM TO PRODUCE AN ELASTOMERIC PAD ON A RAILROAD TIE
The present disclosure provides for an automated spray system (100) to produce an elastomeric pad on a railroad tie. The automated spray system (100) includes a two-component spray system (102) for spraying a two-component reaction mixture to produce the elastomeric pad on the railroad tie. The automated spray system further includes a gantry system (140) having girder (146) that supports the spray applicator.
BALLAST MATS AND METHODS OF FORMING THE SAME
An method and apparatus for coating transportation components such as a bridge deck with a coating. The coating includes a sealant and rubber mixed with a resin and a foaming agent. The apparatus includes a hopper for the rubber, a impingement gun for the resin and a gun assembly that combined the rubber and resin together at a combined nozzle for spraying.
BAND FOR RAILWAY TRACK BLOCK AND BOOT COMBINATION
A band adapted for use as a seal around an upper edge of a boot adapted for holding a block to which a rail is fastened, includes an elongated body having an outer face, an inner face, a first end and a second end. The first and second ends of the elongated body are secured to each other to form the band. An inner face of the elongated body is smooth and an outer face thereof includes a plurality of longitudinally spaced ribs. The ribs extend from the first end of the band to the second end thereof. The elongated body is made from an electrically insulating elastomeric material.
Switch
A switch (1) for a track system for rail vehicles, wherein the switch (1) has rails (2) and a sequence of sleepers (4) and, in each case on an upper side (5) of the respective sleeper (4), at least two of the rails (2) are fixed to each other in pairs opposite each other, and in each case an intermediate layer (6) is arranged between each one of the rails (2) and the respective sleeper upper side (5), and the sleepers (4) each have a sleeper pad (8) on their undersides (7), opposite their respective upper sides (5), and the sleeper pads (8) each have at least one elastomer layer (9), wherein the intermediate layers (6) each have at least one elastomer layer (10).
SWITCH
A switch (1) for a track system for rail vehicles, wherein the switch (1) has rails (2) and a sequence of sleepers (4) and, in each case on an upper side (5) of the respective sleeper (4), at least two of the rails (2) are fixed to each other in pairs opposite each other, and in each case an intermediate layer (6) is arranged between each one of the rails (2) and the respective sleeper upper side (5), and the sleepers (4) each have a sleeper pad (8) on their undersides (7), opposite their respective upper sides (5), and the sleeper pads (8) each have at least one elastomer layer (9), wherein the intermediate layers (6) each have at least one elastomer layer (10).
RESILIENT SOLE AND METHOD FOR MANUFACTURING SAME
Resilient sole 1 which is attached to a concrete layer (2) or which is positioned between a concrete layer (2) and ballast (3), and which is formed by a layer (4) of recycled rubber, in the revulcanised state after devulcanisation, and a layer (5) of structured fibres which is arranged so as to be in contact with the rubber layer, the fibres being partially impregnated in the rubber layer and having a free thickness (8) of structured fibres, assembly comprising the sole and method for manufacturing same.
