1. A method for guiding a tie gang to perform maintenance, comprising:
receiving at least one location signal including location data having latitude and longitude values for a machine, a maintenance item, or both;
comparing, via a processor, the latitude and longitude values with stored location information to calibrate a location of the machine, wherein the stored location information is stored in a file associated with a maintenance operation request including the at least one location signal, wherein calibrating the location of the machine includes updating the stored location information in the file associated with the maintenance operation request based on the latitude and longitude values of the at least one location signal when the stored location information and the latitude and longitude values of the at least one location signal are different;
calculating a distance of a path from the location of the machine to a maintenance item location; and
traveling to the maintenance item location.
