摘要： A wayside lubrication apparatus (10) for applying a lubricant (26) in response to the presence of a train (14) on the rail (14). To avoid excessive lubricant on the rail, lubricant may be applied in response to a second train only if a predetermined time period has elapsed between first and second trains. The amount of lubricant applied in response to the second train may be controlled by refilling a lubricant container (68) at a controlled rate. The application of lubricant may be terminated before a number of rearmost load cars (46) of the train pass the lubricant applicator (28) so that the quantity of lubricant remaining on the rail is reduced by the wheels (40) of the cars at the end of the train. This prevents the lubricant from reducing the traction capability of the drive wheels (38) of the next oncoming locomotive (16). Operation of the lubricant dispensing apparatus (22) may be bypassed by an operator-controlled bypass device (60) located on-board the train.

摘要： An adhesion control system for a locomotive is provided for achieving and maintaining a maximum adhesion value. The adhesion control system includes a means for determining from an appropriate adhesion-creep curve an ideal creep rate that must be achieved and maintained in order to achieve and maintain a maximum adhesion value, a means for estimating an actual creep rate through the measurement or estimation of motor or wheel acceleration and locomotive acceleration, a means for selecting a creep rate set point based on a comparison of the actual creep rate and the ideal creep rate where the creep rate set point is set to a positive value if the actual creep rate is less than the ideal creep rate minus an acceptable differential and is set to a negative value if the actual creep rate is greater than the ideal creep rate plus the acceptable differential, and a means responsive to the creep rate set point for adjusting the operation of the locomotive so that the maximum adhesion value may be realized where the actual creep rate is increased if the creep rate set point is set to the positive value and is decreased if the creep rate set point is set to the negative value.

摘要： A system is provided for use with, a wheeled vehicle. The system includes a media reservoir capable of holding a tractive material that includes particulates; a nozzle in fluid communication with the media reservoir; and a media valve in fluid communication with the media reservoir and the nozzle. The media valve is controllable between a first state in which the tractive material flows through the media valve and to the nozzle, and a second state in which the tractive material is prevented from flowing to the nozzle. In the first state, the nozzle receives the tractive material from the media reservoir and directs the tractive material to a contact surface such that the tractive material impacts the contact surface that is spaced from a wheel/surface interface. The system can modify the adhesion or the traction capability of the contact surface with regard to a subsequently contacting wheel.

摘要： A locomotive (or other rail vehicle) truck and method for distributing weight asymmetrically to axles of the truck includes a first axle of a truck uncoupled from a traction system of the locomotive and a first suspension assembly coupling the first axle to the truck for applying to the first axle a first portion of a locomotive weight. The truck also includes a second axle coupled to the traction system and a second suspension assembly coupling the second axle to the truck for applying a second portion of the locomotive weight to the second axle that is greater than the first portion so that weight is asymmetrically distributed to the first axle and the second axle so as to transmit a corresponding incremental amount of tractive effort for a given amount of a driving torque applied to the second axle via the traction system of the locomotive. The axle weight distribution involves relatively slight weight distribution compared to the nominal weights normally carried by the axles.
