Abstract: A system for increasing the efficiency of the movement of a railroad car over a length of rail, including a fluid reservoir for containing a quantity of efficiency enhancing fluid, a fluid dispensing member, a fluid pump connected in fluidic communication between the reservoir and the fluid dispensing member for dispensing a predetermined quantity of fluid through the fluid dispensing member, a microprocessor operationally connected to the fluid pump, and a first sensor for generating a first sensor signal in response to a railroad car crossing a predetermined section of track and operationally connected to the microprocessor. The fluid dispensing member is positioned along a railroad portion substantially equal in length to the circumference of a railroad car wheel to provide a substantially continuous flow of efficiency enhancing fluid substantially equal in length to the circumference of a railroad car wheel onto the rail portion when the predetermined quantity of fluid is dispensed.

Abstract: The tracks of a railroad yard system have an access track and a plurality of switches leading to a plurality of yard tracks are lubricated by a lubricating station positioned on the access track. In addition to lubricating the tracks, lubrication nozzles are directed at the switch plates and switch points of the switches of the system. Detectors are positioned on the yard tracks to determine the speed of the cars as they roll down track and into the yard, and a computer, responsive to these detectors, control the discharge of lubricant by the lubricating station. Detectors are also positioned near each switch plate to detect when each switch plate moves, and a dispensing system dispense lubricant through the nozzle directed toward a switch plate whenever the switch plate is moved.

Abstract: A system for deicing a railroad portion, such as a switch point, switch plate, or length of rail, including a reservoir of deicing fluid, a deicing fluid dispensing assembly connected in hydraulic communication with the reservoir, at least one ice sensor positioned to report the temperature of the predetermined portion of the railroad system, and a deicing fluid flow actuator operationally connected to the reservoir. Energization of the flow actuator urges deicing fluid through the fluid dispensing assembly and onto the railroad portion.

Abstract: To lubricate a length of track, a plurality of lubricating nozzles are provided. Each nozzle is fed by the output of a single positive displacement pump, and all the pumps are controlled by a computer. Vibration sensors, sound sensors, or L/V ratio sensors detect physical qualities which occur as a train passes a given point, and another detector measures the time between successive wheels on the truck of a car as it passes a given point to measure train speed. The computer compares the output readings measured by the detector to a table of outputs in its memory that are indicative of a lubricated track to determine if lubrication is needed.
