Generally there is a desire to keep the friction between the wheel flange and the gauge face of the rail as low as possible to reduce wear in this area and decrease the rolling/sliding resistance in curves. This can be attained by lubricating the gauge face of the rail with either trackside lubricators or onboard lubricating systems.
