摘要： An embodiment of a rail switch heating system is disclosed, including a controller comprising a processor and memory, an electrically resistive heating element coupled to the controller, the heating element configured for mounting to and heating a railroad rail, and software stored on the memory for executing the steps of: (a) automatically determining a pulse width modulated (PWM) cycle corresponding to a target energy consumption for cycling the heating element on and off; and (b) cycling the heating element on and off according to the PWM cycle.

摘要： Systems, devices, media, and methods are presented for controlling remote equipment in a network. A switch heater control system includes a weather modeling function. The system periodically obtains weather data according to a predetermined time interval. Based on the closest weather data set, the weather modeling function generates a hyperlocal forecast associated with each switch heater location. The system includes an active snowfall mode and a maintenance mode that controls heating based on an estimate of local snow depth, adjusted for wind conditions and passing trains. When the hyperlocal forecast indicates heating is required, the system calculates a melt duration, starts a timer, and transmits a start signal to the switch heater.

摘要： A superstructure device (10) for a set of points having a switch support which is composed of a block of high-strength steel and which has stock and short point rails which delimit said switch support and are formed integrally from the block, wherein the block is connected to a lower part composed of a material other than the high-strength steel, such as mild steel, and is in particular connected in a materially joined fashion, wherein the block extends essentially over the entire length of a switch rail device as the superstructure device on both sides beyond the switch support, and the lower part is a means of supporting the block in the form of at least two supports which are spaced apart from one another.

摘要： A track rail heating assembly that is adapted to position a heater element in spaced relation proximate to a surface of a track rail of a railroad. The assembly includes at least one heating element, and a housing that is operable to at least partially surround the heating element while positioning the heating element near to track rail. The hood positions the heating element relative to the rail section such that a gap exists between the heating element and the rail section. As the heating element does not contact the rail, the heating element cannot form an electrical by-pass for signals passing through the rail section. The assembly further incorporates a flexible barrier that at least partially isolates a side surface of the track rail from ambient conditions to reduce heat loss.

摘要： A Geothermal Rail Cooling and Heating System is a reversible system process that accelerates heat transfer between the steel rail used in railway track and the adjacent earth. It is comprised of the Rail Heat Exchangers specially shaped to fit tightly inside the rail web, a refrigerant cycling on its physical condensing and evaporative characteristics, a mechanical and power supply system, and an underground tubing loop system for heat dissipation or absorption. When the railroad track undergoes a range of temperature changes that results in rapid rail expansion, it may cause track buckling or sun kink. Upon detection of such occurrence, the system responds with cooling effect to slow down expansion, and simultaneously reduce the risk of track failure. By switching the direction of refrigerant flow utilizing the system built-in reversing valve, the function is alternated for the evaporator and condenser to enable heating instead of cooling.
