1. A method for identifying a location of a wheel of a rail vehicle, the method comprising:
- producing a first signal representative of a potential difference between leads electrically coupled with a wheel gate transducer;
modifying the first signal received over a first channel to produce a second signal over a second channel, the second signal differing from the first signal; and
monitoring the first and second signals over the first and second channels to identify the location of the wheel relative to the wheel gate transducer.

Abstract
A method for identifying a location of a wheel of a rail vehicle includes producing a first signal representative of a potential difference between leads electrically coupled with a wheel gate transducer and modifying the first signal that is received over a first channel to produce a second signal over a second channel, where the second signal differs from the first signal. The method further includes monitoring the first and second signals over the first and second channels to identify the location of the wheel relative to the wheel gate transducer.
