Flat Wheel Detector (FWD)

Wheels of the railway vehicles are subject to extreme stresses and strains, which inevitably lead to wear and tear. The flat wheel detection system uses precision fiber-optic technology to detect off-center wheels and flat wheel sections of coaches with wheel loads of up to 30t. It is designed as a stand-alone system or as a companion system to the HABD system. In addition to the wheel status, FWD can also report ballast status, train weight and overloads.
