The apparatus has a supply of lubricant 116 leading to a first dispensing nozzle 140 arranged to deliver lubricant to at least a part of the field side part of the wheel tread but not at least a part of the tread central running part. The apparatus is carried by the rail vehicle and its supply of lubricant 116 may be a low coefficient of friction lubricant. The apparatus may be used to reduce rolling contact fatigue In the field side part of the wheel. There may be a second nozzle directed toward a different part of the wheel tread, e.g. the flange. The apparatus has also a means 106 for introducing compressed air to drive lubricant 116 through to the nozzles. The apparatus has GPS or an RFID tag to determine the vehicle position for possible lubricant dispensation.
