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.
