A communications system for use in transmitting data in a railroad system is provided. The communications system includes a track circuit having a plurality of rails configured to transmit an electrical signal thereon, a first processor communicatively coupled to the track circuit via a first locomotive on said track circuit, and a trackside communications station operable to output cab signaling data, wherein the trackside communications station includes a second processor communicatively coupled to the track circuit. The first processor is programmed to compare a received data signal to a pre-stored database, and generate a response based on the comparison. The second processor is programmed to generate a corrected signal using the generated response.

1. A method comprising: correlating a data signal to a trackside communications station;transmitting the data signal from the trackside communications station along a track circuit;receiving the transmitted signal by a first rail vehicle;comparing the received signal to a pre-stored database;generating a response based on a comparison of the received signal to the pre-stored database;transmitting the response via the track circuit to the trackside communications station; andautonomously adjusting the data signal using the response, at a processor associated with the trackside communications station, to generate a corrected data signal. 2. A method in accordance with claim 1, further comprising transmitting the response wirelessly to an external receiver. 3. A method in accordance with claim 1, further comprising identifying a faulty trackside communications station based on the response that is transmitted. 4. A method in accordance with claim 3, wherein identifying the faulty trackside communications station further comprises locating the faulty trackside communications station using triangulation. 5. A method in accordance with claim 1, further comprising identifying a faulty processor onboard the first rail vehicle based on the comparison. 6. A method in accordance with claim 1, further comprising identifying a faulty onboard processor when at least one rail vehicle rejects the transmitted response generated by the faulty onboard processor. 7. A method in accordance with claim 1, further comprising updating an output parameter of the trackside communications station, wherein the output parameter includes at least one of a signal amplitude, a signal period, a carrier frequency, or a duty cycle. 8. A communications system comprising: a first processor communicatively coupled to a track circuit via a first rail vehicle on said track circuit, the track circuit comprising one or more rails configured to transmit an electrical signal thereon, said first processor configured to monitor a quality of a received data signal transmitted over the track circuit, wherein said first processor, when monitoring the quality of the received data signal, is configured to:compare the received data signal to a pre-stored database, the received data signal correlated to and received from a trackside communications station;generate a maintenance response based on the comparison of the received data signal to the pre-stored database; andcommunicate the maintenance response via the first rail vehicle and the track circuit to the trackside communications system; anda second processor, the second processor associated with the trackside communications station and communicatively coupled to said track circuit, the second processor configured to receive the generated maintenance response communicated via the first rail vehicle and to autonomously adjust the received data signal to generate a corrected signal for transmission via the track circuit using the generated maintenance response. 9. A system in accordance with claim 8, wherein said second processor is further configured to transmit the corrected signal along said track circuit to at least one rail vehicle. 10. A system in accordance with claim 9, wherein said first processor is further configured to transmit the response along said track circuit to at least one second locomotive rail vehicle. 11. A system in accordance with claim 8, wherein said first processor is configured to compare a received data signal to a pre-stored database comprising at least one of a signal amplitude, a signal period, a carrier frequency, and a duty cycle. 12. A system in accordance with claim 8, further comprising a remote system coupled in electronic data communication with said communications system. 13. A system in accordance with claim 12, wherein said first rail vehicle further comprises a wireless transmitter configured to transmit the maintenance response to said remote system. 14. A trackside communications station system operable to output cab signaling data, said trackside communications station system comprising a processor communicatively coupled to a track circuit, the processor configured to generate a corrected signal using a generated response received via a first rail vehicle, wherein the generated response corresponds to a signaling data signal previously communicated from the trackside communications station system via the track circuit to the first rail vehicle, and the generated response is based on a comparison of the signaling data signal to a pre-stored database by the first rail vehicle, and wherein the processor is configured to autonomously adjust the signaling data signal previously communicated to generate the corrected signal using the generated response. 15. A trackside communications station system in accordance with claim 14, wherein said processor is configured to transmit the corrected signal along the track circuit. 16. A system comprising: a first processor communicatively coupled to a track circuit, said first processor associated with a rail vehicle and configured to execute a process that facilitates monitoring a quality of a data signal transmitted over the track circuit to the rail vehicle, wherein said processor, when executing said process, is configured to:receive the data signal from a trackside communication station, the data signal correlated to the trackside communication station;compare the data signal that is received to a pre-stored database; andgenerate, based on the comparison, a maintenance response instructing the trackside communication station to autonomously adjust the data signal to generate a corrected signal for transmission over the track circuit using the maintenance response. 17. A system in accordance with claim 16, wherein said processor is further configured to transmit the maintenance response along the track circuit to the trackside communications station and at least one second rail vehicle. 18. A system in accordance with claim 17, wherein the pre-stored database comprises at least one of a signal amplitude, a signal period, a carrier frequency, or a duty cycle.
