A system for detecting wheel-slip comprising: (a) means for detecting the speed of at least three wheels of a railroad car, (b) means for using the wheel with the highest speed as the basic speed, (c) means for determining the speed differential of each wheel to ascertain the amount of reduction of

A system for detecting wheel-slip comprising: (a) means for detecting the speed of at least three wheels of a railroad car, (b) means for using the wheel with the highest speed as the basic speed, (c) means for determining the speed differential of each wheel to ascertain the amount of reduction of the speed when the speed exceeds a set level, (d) means for using the speed differentials to determine when a slip of the wheel will take place, (e) means for establishing the set value to be a first set value and a second set value with a value higher than the first set value, (f) means for ascertaining when the first set value is exceeded by the speed differential when all the speeds of the wheels are less than the second set value and the speed differential and all the degrees of acceleration determined by the differentiation of each wheel falling below the basic acceleration slipping is determined to be occurring on all the wheels so that information on all the wheels which are slipping forms a storable output, and (g) means for causing all the wheel-slipping information to be outputted regardless of the magnitude of the acceleration so that wheel-slipping information is stored and when at least one of the speed differentials has exceeded the first set value and the wheel-slipping information is stored.
