Abstract: A rail gauge face applicator is provided. The gauge face applicator comprises a resilient pad comprising one or more than one channel extending from one or more than one inlet to one or more than one outlet. The one or more than one channel is operable from a closed position when the pressure within the channel is low to an open position when the pressure within the channel is raised. Thus, when the pressure of the friction modifying material is raised the one or more than one channel opens and material can be delivered from the one or more than one outlet. The applicator further comprises a rail engagement element which allows the gauge face applicator to be positioned appropriately to engage a rail. The applicator may be less prone to clogging and may be more efficient at delivering friction modifying material efficiently than prior art applicators.
