First Claim
1. A system for reducing wheel sliding on a locomotive, the locomotive traveling at a locomotive speed and comprising a plurality of axles and respective pair of wheels, the system comprising:
- at least one speed inferring system coupled to each of said plurality of axles and respective pair of wheels for detecting rotation of each axle and generating at least one detection signal based upon detecting rotation of each axle, said at least one detection signal comprising at least one speed signal indicative of locomotive speed and at least one non-rotating signal indicative of a non-rotating axle; and
a main controller coupled to each of said at least one speed inferring system and responsive to said at least one detection signal, said main controller for identifying said at least one non-rotating signal and for initiating at least one alert signal of said at least one non-rotating axle of said plurality of axles based upon identifying said at least one non-rotating signal of said at least one detection signal.

Abstract
A system for reducing wheel sliding on a locomotive is provided for a locomotive including a plurality of axles. The system includes one or more speed inferring systems coupled to each axle to detect rotation of each axle and generate detection signals based upon detecting rotation of each axle. The detection signals include one of speed signals indicative of locomotive speed and non-rotating signals indicative of a non-rotating axle. More particularly, a main controller is coupled to each speed inferring system and is responsive to each detection signal. The main controller identifies non-rotating signals of the detection signals to initiate one or more alert signals of one or more respective non-rotating axles of the plurality of axles. Additionally, the main controller is coupled to an operator panel to alert a locomotive operator of an applied status of a locomotive parking brake in response to the alert signal.
