What is claimed is: 1. A method for monitoring the neutral temperature of a railway rail, the method comprising the acts of: installing at a rail site a field sensor system to collect data relating to the neutral temperature of a rail at the rail site; logging a first set of data relating to the neutral temperature of the rail at the rail site; collecting the first set of logged data relating to the neutral temperature of the rail using a data collection device; storing the first set of logged data relating to the neutral temperature of the rail on a storage medium; logging a second set of data relating to the neutral temperature of the rail at the rail site; collecting the second set of logged data relating to the neutral temperature of the rail using the data collection device; storing the second set of logged data relating to the neutral temperature of the rail on the storage medium; and accessing the storage medium and analyzing the first set of logged data and the second set of logged data by displaying a representation of the data on a display screen. 2. The method of claim 1, wherein the act of installing at a rail site a field sensor system includes the act of: calibrating a component of the field sensor system. 3. The method of claim 2, wherein the act of calibrating a component of the field sensor system includes the act of: establishing the initial neutral temperature of the rail at the rail site. 4. The method of claim 3, further comprising the act of: calculating the neutral temperature of the rail based on the first set of logged data. 5. The method of claim 4, further comprising the act of: calculating the neutral temperature of the rail based on the second set of logged data. 6. The method of claim 1, further comprising the act of: calculating the difference between the neutral temperature of the rail based on the first set of data and the neutral temperature of the rail based on the second set of data. 7. A method for monitoring the neutral temperature of a railway rail, the method comprising the acts of: installing at a first rail site a first field sensor system to collect data relating to the neutral temperature of a rail at the first rail site; installing at a second rail site a second field sensor system to collect data relating to the neutral temperature of a rail at the second rail site; logging a first set of data relating to the neutral temperature of the rail at the first rail site; logging a second set of data relating to the neutral temperature of the rail at the first rail site; collecting, at a data collection unit, the first set of data and the second set of data relating to the neutral temperature of the rail at the first rail site, where the first field sensor system communicates with the data collection unit through a wireless interface; logging a first set of data relating to the neutral temperature of the rail at the second rail site; logging a second set of data relating to the neutral temperature of the rail at the second rail site; collecting, at the data collection unit, the first set of data and the second set of data relating to the neutral temperature of the rail at the second rail site, where the data collection unit receives the first set of data and the second set of data relating to the neutral temperature of the rail at the second rail site through a wireless interface; and analyzing, at an analysis location that is not at the first rail site and that is not at the second rail site, the first set of data relating to the neutral temperature of the rail at the first rail site and the second set of data relating to the neutral temperature of the rail at the first rail site to determine the condition of the rail at the first rail site. 8. The method of claim 7, where the act of collecting the first set of data and the second set of data relating to the neutral temperature of the rail at the first rail site is carried out automatically without requiring intervention by data collection personnel, and where the act of collecting the first set of data and the second set of data relating to the neutral temperature of the rail at the second rail site is carried out automatically without requiring intervention by data collection personnel. 9. The method of claim 7, where the act of installing at a first rail site a first field sensor system includes the act of calibrating a component of the first field sensor system. 10. The method of claim 9, where the act of calibrating a component of the first field sensor system includes establishing the initial neutral temperature of the rail at the first rail site. 11. The method of 10, further comprising the act of: analyzing, at the analysis location, the first set of data and the second set of data relating to the neutral temperature of the rail at the second rail site. 12. A system for monitoring the neutral temperature of a railway rail, the system comprising: (a) a first field sensor system installed on a rail at a first railway site, where the first field sensor system is configured to collect data relating to the neutral temperature of the rail at the first railway site, where the first field sensor system logs a first set of data relating to the neutral temperature of the rail at the first railway site, and where the first field sensor system later logs a second set of data relating to the neutral temperature of the rail at the first railway site; (b) a second field sensor system installed on a rail at a second railway site, where the second field sensor system is configured to collect data relating to the neutral temperature of the rail at the second railway site, where the second field sensor system logs a first set of data relating to the neutral temperature of the rail at the second railway site, and where the second field sensor system later logs a second set of data relating to the neutral temperature of the rail at the second railway site; and (c) a data collection unit that is configured to receive data relating to the neutral temperature of the rail at the first railway site and relating to the neutral temperature of the rail at the second railway site, where the data collection unit is not located at the first railway site and is not located at the second railway site, and where the data collection unit is configured to receive the first set of data relating to the neutral temperature of the rail at the first railway site and the second set of data relating to the neutral temperature of the rail at the first railway site to enable analysis of the condition of the rail at the first railway site. 13. The system of claim 12, where the data collection unit is configured to receive data through a wireless interface. 14. The system of claim 13, where the data collection unit is configured to receive data without assistance from data collection personnel. 15. The system of claim 14, where the data collection unit is further configured to receive data relating to the neutral temperature of the rail at the first railway site and relating to the neutral temperature of the rail at the second railway site to enable analysis of the condition of the rail at the first railway site and the condition of the rail at the second railway site. 16. The system of claim 15, further comprising: (d) a computer configured to analyze the condition of the rail at the first railway site and the condition of the rail at the second railway site.
