A brush assembly for engaging and conducting electricity to or from a surface is provided. The brush assembly comprises a monolithic, electrically conductive bus block and a bristle holder removably attached to the bus block. The bristle holder is formed as a monolithic block having a plurality of parallel bristle holes formed therethrough. The brush assembly further comprises a plurality of bristle assemblies, each bristle assembly having an elongate, electrically conductive bristle and an electrically conductive bristle cap having a sleeve, the proximal end of the bristle being secured within the sleeve so that the bristle is in electrical communication with the sleeve. At least a portion of the bristle cap of each bristle assembly is removably disposed within an associated bristle hole so that the bristle of each bristle assembly extends through its associated bristle hole and downwardly away from the lower bristle holder surface. Each bristle cap is in electrical communication with the bus block.

A data processing system is provided for use in conjunction with a rail inspection system having a detection carriage with a plurality of sensor units configured to sense discontinuities in a rail of a railroad track as the detector carriage travels along the railroad track. The system includes a data processing and recording computer connectable to the plurality of sensor units for receiving sensor data therefrom. At least one processor card may be included in the data processing and recording computer that includes at least one data object builder configured for building data objects using the sensor data from the plurality of sensor units. The at least one processor card may also include device for synchronizing the data objects with respect to location along the rail. The system may further include a defect detection module in the data processing and recording computer. The defect detection module is in communication with the at least one data object builder and is configured for using the data objects to determine rail locations having suspected defects.

A railroad rail inspection system is provided for use in conjunction with a non-railbound vehicle having an equipment bay. The system comprises a detector carriage adapted for being propelled over a two-rail railroad track by the non-railbound vehicle. A magnetic induction sensor system adapted for magnetic induction inspection of at least one rail of the track is attached to the detector carriage. The system further comprises a data acquisition system in communication with the magnetic induction sensor system, the data acquisition system including at least one data processor adapted for processing induction data received from the magnetic induction sensor system. The system further comprises a power supply system adapted for supplying electrical power to the magnetic induction sensor system. The data acquisition system and the power supply system are configured for disposition and operation within the equipment bay of the non-railbound vehicle.

A method and apparatus for testing rails for structural defects, the rails being associated with a railroad track include providing and using a first rail traveling vehicle for movement along a segment of rails followed by a second rail traveling vehicle for disposition behind the first rail traveling vehicle along the rails for testing with the first rail traveling vehicle having a first digital computer and a first analog computer and the second rail traveling vehicle having a second computer for display of data associated with the rails. A first modem assembly is provided in the first vehicle with a second modem assembly being provided in the second vehicle in communication with the first modem whereby data may be exchanged between the rail traveling vehicles. During testing, the first rail traveling vehicle transmits complete digital and analog rail structural and defect location information data to the second computer for analysis and action by the operators of the second vehicle.
