A special trackwork assembly including a special trackwork body formed to support wheels of a train moving over a running surface portion of an exterior surface of the special trackwork body that generate traffic-related vibrations of the special trackwork body having one or more frequencies of interest. The special trackwork assembly also includes one or more tuned mass dampers secured to the special trackwork body and formed to vibrate, in response to the traffic-related vibrations of the special trackwork body, at the frequency of interest, to at least partially dampen the traffic-related vibrations of the special trackwork body.

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.

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.
