Abstract
A rail applicator assembly includes a rail having a head portion, a base portion, and a web portion extending between the head portion and the base portion. The head portion defines an outer surface. An applicator for applying a friction modifying material to the surface of the rail includes a foam body and an applicator support. The foam body is secured to the applicator support and defines a flow passageway that extends through the foam body for friction modifying material to flow through.
Claims20
A rail applicator comprising:
- an elongate resilient polymeric body configured to apply friction modifying material to a field surface of a head portion of a rail, the elongate resilient polymeric body comprising a flow passageway consisting of one conduit that extends through the elongate resilient polymeric body for the friction modifying material to flow through;
- and
- a rigid applicator support, wherein the elongate resilient polymeric body comprises a top surface and a bottom surface and wherein the bottom surface of the elongate resilient polymeric body is secured to a surface of the rigid applicator support,
- wherein the elongate resilient polymeric body is sufficiently resilient to compress when the top surface is contacted by a passing rail wheel and to subsequently return to its original position.
