A system is provided for regulating the speed of a rail vehicle traveling along a track. The track has a pair of rails. The system includes a temperature sensor positioned on an external surface of the rail vehicle. The temperature sensor measures a temperature of one of the rails. The system further includes a controller coupled to the temperature sensor. The controller receives data of the measured temperature, and regulates the speed of the rail vehicle based upon the measured temperature data. A method and computer readable media are also provided for regulating the speed of a rail vehicle traveling along a track.

That which is claimed is: 1. A system for regulating the speed of a rail vehicle traveling along a track, said track having a pair of rails, said system comprising: a pair of temperature sensors positioned on an external surface of said rail vehicle, said pair of temperature sensors being configure
That which is claimed is: 1. A system for regulating the speed of a rail vehicle traveling along a track, said track having a pair of rails, said system comprising: a pair of temperature sensors positioned on an external surface of said rail vehicle, said pair of temperature sensors being configured to measure a temperature of said rails; a controller coupled to said pair of temperature sensors, said controller being configured to receive data of said measured temperature, said controller being configured to regulate said speed of the rail vehicle based upon said measured temperature data; wherein the rail vehicle is front locomotive of a train; and wherein said pair of temperature sensors are positioned on an undersurface of opposing sides of the front locomotive, said undersurface of said opposing sides is selected such that said pair of temperature sensors are positioned above said respective pair of rails. 2. The system of claim 1, wherein said pair of temperature sensors is a pair of infrared sensors aligned with said respective rails, said infrared sensors being configured to measure said temperature of said respective rails based on an infrared spectrum of said respective rails received from said respective rails. 3. The system of claim 2, wherein said controller is configured to receive said measured temperature data of said respective rails from said pair of infrared sensors, said controller is configured to determine a maximum allowable speed of said front locomotive based on said measured temperature data of said respective rails, said maximum allowable speed based on said measured temperature data of said respective rails being stored in a memory of said controller. 4. The system of claim 3, wherein said controller is coupled to a speed sensor of said front locomotive to receive data of said speed of the front locomotive, said controller is configured to reduce said speed of the front locomotive to said maximum allowable speed if said speed of the front locomotive is greater than said maximum allowable speed of the front locomotive. 5. The system of claim 2, said controller is configured to transmit said received measured temperature data of said respective rails to a remote facility having a processor, said remote facility processor being configured to collect said measured temperature data of said respective rails from a plurality of locomotives traveling along a plurality of regions along said track. 6. The system of claim 5, wherein said remote facility processor is configured to evaluate said measured temperature data of said respective rails along said plurality of regions of said track, said remote facility processor is configured to determine a respective maximum allowable speed of said plurality of locomotives traveling along said respective plurality of regions of said track. 7. The system of claim 6, wherein said respective maximum allowable speed of said plurality of regions based on said measured temperature data of said respective rails is stored in a memory of said remote facility processor; said remote facility processor is configured to transmit said respective maximum allowable speed to said plurality of locomotives in said plurality of regions. 8. The system of claim 7, wherein said controller is configured to receive said maximum allowable speed data from said remote facility processor, said controller is coupled to a speed sensor of the front locomotive to receive data of said speed of the front locomotive, said controller is configured to reduce said speed of the front locomotive to said maximum allowable speed if said speed of the front locomotive is greater than said maximum allowable speed of the front locomotive. 9. A method for regulating the speed of a rail vehicle traveling along a track, said track having a pair of rails, said method comprising: positioning a pair of temperature sensors on an external surface of said rail vehicle; configuring said pair of temperature sensors to measure a temperature of one of said rails; configuring a controller coupled to said pair of temperature sensors to receive data of said measured temperature; regulating said speed of the rail vehicle based upon said measured temperature data; wherein said rail vehicle is front locomotive of a train; and wherein said pair of temperature sensors are positioned on an undersurface of opposing sides of the front locomotive, said undersurface of said opposing sides is selected such that said pair of temperature sensors are positioned above said respective pair of rails. 10. The method of claim 9, wherein said pair of temperature sensors is a pair of infrared sensors, said method further comprising: aligning said pair of infrared sensors with said respective rails; and configuring said infrared sensors to measure said temperature of said respective rails based on an infrared spectrum of said respective rails received from said respective rails. 11. The method of claim 10, further comprising: determining a maximum allowable speed of said front locomotive based on said measured temperature data of said respective rails, said maximum allowable speed based on said measured temperature data of said respective rails being stored in a memory of said controller. 12. The method of claim 11, further comprising: coupling said controller to a speed sensor of said front locomotive to receive data of said speed of the front locomotive; and reducing said speed of the front locomotive to said maximum allowable speed if said speed of the front locomotive is greater than said maximum allowable speed of the front locomotive. 13. The method of claim 10, further comprising: transmitting said received measured temperature data of said respective rails to a remote facility having a processor; and collecting said measured temperature data of said respective rails from a plurality of locomotives traveling along a plurality of regions along said track at said remote facility. 14. The method of claim 13, further comprising: evaluating said measured temperature data of said respective rails along said plurality of regions of said track; and determining a respective maximum allowable speed of said plurality of locomotives traveling along said respective plurality of regions of said track. 15. The method of claim 14, further comprising: storing said respective maximum allowable speed of said plurality of regions in a memory of said remote facility processor based on said respective measured temperature data of said respective rails from said plurality of regions; and transmitting said respective maximum allowable speed to said plurality of locomotives in said plurality of regions.
