The Vehicle Identification System enables operators of rolling stock to have visibility of the location and movement of their fleet. Combined with trackside condition monitoring equipment, unsafe conditions can easily be traced back to the offending vehicle.

The VIS 2 is capable of monitoring from 1 to 4 rail lines independently to detect the presence of RF Identification tags located on rolling stock. Tags are paired with vehicles using axle pattern recognition. The vehicle number stored in the RF tag, the vehicle type information, the direction and the speed of movement is constructed to build a train consist. The train consist data is transmitted to back office databases where the information is used by train operators to keep track of train movements in yards, sidings and main lines.
