Claim One:
1. A mobile tracking unit comprising: a rotation measurement unit for generating data substantially indicative of rotational rate of the set of wheels; a motion sensor for generating data indicative of motion at least along a generally vertical axis relative to the railtrack; a data processor coupled to the motion sensor and to the rotation measurement unit for receiving the rotational rate and motion data, said data processor being adapted to detect, based on the received rotational rate and motion data, a defective condition associated with at least one wheel of the wheel set, said data processor being further adapted to detect, based on the received motion data, a defective condition associated with at least a portion of the railtrack; a navigation set for generating data substantially corresponding to a respective railway vehicle position so that the location at which any respective defective condition occurs can be substantially determined; and an electromagnetic radiation emitter for transmitting predetermined data associated with the railway vehicle to a remote location.
