Abstract: In railroad operations, a method and apparatus for optimizing on-board rail lubrication for both curved and tangent track. The apparatus is mounted on the car body of the last locomotive of a locomotive consist behind the last axle. A lubricating device applies two different lubricants, one on the crown of the rail and the other on the gage side. The amount and type of the crown lubricant are chosen such that the crown lubricant is totally consumed by the passage of the train wheels. The amount of application of the two lubricants is controlled by a microprocessor. A new sensor has been devised which measures degree of rail curve and estimates the angle of attack of the wheel on the rail by converting lateral displacement into either of the two quantities. This value is provided to the microprocessor. Other sensors measuring speed, temperature, humidity, etc. provide input signals to the microprocessor. This invention not only reduces the friction coefficient between the wheel flanges and the rail but also reduces the forces between the wheel flanges and the rail. Both rail and wheel wear are reduced while simultaneously also reducing the fuel consumed in the train.

Abstract: In railroad applications, an improved method and apparatus for optimizing on-board rail lubrication for both curved and tangent track. The lubricants are applied by an apparatus directly to the rails behind the last axle of the last locomotive of a locomotive consist. The system uses lubricant delivery nozzles which are integrated with the sand pipe and nozzle for each rail. The lubricant nozzles are aimed toward the wheel rail contact at a distance of several inches behind the contact for accurate application of one lubricant on the top of the rail (TOR) and another on the rail gage side (RAGS). The lubricant quantities sprayed on the rail are controlled by a miroprocessor with the use of a flow injection pulse, system or flow control valves. Furthermore, the microprocessor triggers sand application when emergency brakes are applied. A new method of determination of trailing tons in the train is used by averaging the total power used by the locomotives at a certain speed.

Abstract: This invention concerns a creepage control system for locomotives that optimizes adhesion while minimizing wasted energy, rail/wheel wear and shock loading on the drive train. The basis of the invention is to always maintain a small but positive value of the slope of the wheel-rail adhesion creep curve (or differential of adhesion versus creep) for all traction axles of the locomotive through microprocessor control. The value of the differential of adhesion versus creep is used to define an operating window for control and operation of motors continually in the optimum domain when high adhesion is demanded. When, due to a sudden increase in rail contamination, the value of the control function becomes negative, the microprocessor control reduces the generator excitation in stages until the function becomes positive and inside the operating window again. The microprocessor controls a rail cleaning system which is turned on or off depending on the cleanliness of the rail. It also controls a rail sanding system which is turned on or off depending on the magnitude of wheel creep.

Abstract: A method and apparatus for enhancing traction capacity and energy efficiency of locomotives and powered cars while helping to maintain the crown of the rail profile for better ride quality of trains. This is achieved by utilizing beneficially the effects of lateral creepage of a number of small, hard nonpowered cleaning wheels with alternately opposite angles of attack. The apparatus may include deflector shields and hot air jets for cleaning and preparing the rail crown surface, when the apparatus is used in locomotives or cars. An arrangement for automatically adjusting the angle of attack of the cleaning wheels is also given. The degree of cleaning of the rails can be electrically controlled by the locomotive engineer as desired including shutting off the device altogether.

Abstract: A wayside lubricator for railroad cars has a number of sensors mounted adjacent the track which detect the approach and passage rail cars. A lubricant supply and a pressurizing system are mounted adjacent the track and in fluid communication with a control valve and spray nozzle. The spray nozzle is aimed to shoot lubricant into a target zone when the control valve is opened. The spray nozzle is turned on for a defined duration of time so that the quantity of the lubricant is kept under control. Application of the lubricant to the wheels of the locomotive is avoided by detecting locomotive wheels and leaving the valve closed until they pass. This invention reduces the friction between the wheel tread and rail on curves for the trailing cars and thus reduces the friction and the force that is experienced by the wheel flanges on curves.

Abstract: A lubrication system for a railroad locomotive applies a lubricant with great accuracy in computer-controlled, precise quantities behind the last axle of the last locomotive such that the lubricant is consumed by the time the entire train has passed under all track, speed, temperature and train size conditions. Hydraulic pulse-width modulation (PWM or % PWM) controls the quantity of lubricant delivered. Time is divided into a series of windows each consisting of a few seconds. Lubricant delivered from a pressurized tank through long hoses to a solenoid controlled valve is then metered by the duration within this time window for which the computer computes and opens the valve. Compensation is provided for train tonnage and lubricant temperature as well as track curvature and train speed.
