Non-destructive testing methods, such as Magnetic Barkhausen Noise method, are widely used on railways for examining the stress state of running railway rails. Detailed information about the morphology of the microstructure features of the rail surface is derived by Scanning Electron Microscopy. Phase composition, hardness and residual stress state of the rails are determined by MBN signal.
