Claims

1. 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 for use in calculating the neutral temperature of the rail at the first railway site,

where the first field sensor system collects a first set of data for use in calculating the neutral temperature of the rail at the first railway site, and

where the first field sensor system later collects a second set of data for use in calculating 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 for use in calculating the neutral temperature of the rail at the second railway site,

where the second field sensor system collects a first set of data for use in calculating the neutral temperature of the rail at the second railway site, and

where the second field sensor system later collects a second set of data for use in calculating the neutral temperature of the rail at the second railway site;

(c) a wireless network used by the first field sensor system and the second field sensor system to transfer data to a receiving apparatus,

where the first field sensor system transfers over the wireless network the first set of data and the second set of data collected at the first railway site, and

where the second field sensor system transfers over the wireless network the first set of data and the second set of data collected at the second railway site; and

(d) an apparatus that evaluates the condition of the rail at the first railway site based on the first set of data collected at the first railway site and the second set of data collected at the first railway site,

where the apparatus is not located at the first railway site and is not located at the second railway site, and

where the apparatus is configured to evaluate the neutral temperate of the rail at the first railway site based on the first set of data collected at the first railway site and the second set of data collected at the first railway site, and carry out a notification function if the evaluation suggests that the condition of the rail at the first railway site is unsafe.

2. The system of claim 1, where the apparatus is configured to evaluate the neutral temperate of the rail at the second railway site based on the first set of data collected at the second railway site and the second set of data collected at the second railway site.

3. A method for monitoring the neutral temperature of a railway rail, the method comprising the acts of:

(a) installing a first field sensor system on a rail at a first railway site, where the first field sensor system is configured to collect data that can be used to calculate the neutral temperature of the rail at the first railway site,

where the first field sensor system collects a first set of data that can be used to calculate the neutral temperature of the rail at the first railway site, and

where the first field sensor system later collects a second set of data that can be used to calculate the neutral temperature of the rail at the first railway site;

(b) installing a second field sensor system on a rail at a second railway site, where the second field sensor system is configured to collect data that can be used to calculate the neutral temperature of the rail at the second railway site,

where the second field sensor system collects a first set of data that can be used to calculate the neutral temperature of the rail at the second railway site, and

where the second field sensor system later collects a second set of data that can be used to calculate the neutral temperature of the rail at the second railway site;

(c) communicating over a wireless medium information from the first field sensor system,

where the first field sensor system transfers over the wireless medium the first set of data and the second set of data collected at the first railway site;

(d) communicating over a wireless medium information from the second field sensor system,

where the second field sensor system transfers over the wireless medium the first set of data and the second set of data collected at the second railway site; and

(e) enabling evaluation of the condition of the rail at the first railway site based on the first set of data collected at the first railway site and the second set of data collected at the first railway site,

where the condition of the rail is evaluated by calculating the neutral temperate of the rail at the first railway site based on the first set of data collected at the first railway site and the second set of data collected at the first railway site, thereby enabling a determination of whether the condition of the rail is potentially unsafe.

4. The method of claim 3, where the act of enabling evaluation of the condition of the rail includes determining whether the rail is potentially unsafe due to a potential rail break.

5. The method of claim 3, where the act of enabling evaluation of the condition of the rail includes determining whether the rail is potentially unsafe due to a potential rail kink.

6. The method of claim 3, where the act of installing a first field sensor system on a rail at a first railway site includes the act of:

calibrating a component of the first field sensor system and establishing the initial neutral temperature of the rail.

7. The method of claim 3, further comprising the acts of:

calculating the neutral temperature of the rail at the first railway site based on the first set of data; and

calculating the difference between the neutral temperature of the rail at the first railway site based on the first set of data and the neutral temperature of the rail based on the second set of data.

8. The method of claim 3, where the act of communicating over the wireless medium includes communicating with a vehicle traveling on the railway rail the first set of data and the second set of data collected at the first railway site.

9. The method of claim 3, where the act of communicating over the wireless medium includes communicating with a vehicle traveling on the railway rail a set of data collected at the first railway site and a set of data collected at the second railway site.

10. The method of claim 3, where the act of communicating over the wireless medium includes communicating, without assistance from data collection personnel, the first set of data and the second set of data collected at the first railway site.

11. The method of claim 3, where the act of communicating over the wireless network includes communicating, without assistance from data collection personnel, a set of data collected at the first railway site and a set of data collected at the second railway site.

12. A system for monitoring the neutral temperature of a railway rail, the system comprising:

(a) a plurality of field sensor systems, each installed at one of a plurality of locations on a railway,

where each of the field sensor systems are configured to log data that can be used to perform a neutral temperate calculation relating to the railway rail,
