Abstract
Tests performed by Deutsche Bahn AG have shown that eddy-current brake introduced in modern high speed trains disturb signals of axle counters causing excess axle counts. Apart from design modifications at the eddy-current brake, it was also considered to improve the axle counter's detection mechanism. In a project at IITB a patent pending mechanism based on pattern recognition methods was developed to differentiate the signal patterns of wheels and eddy-current brake. Pattern recognition was necessary, because due to a wide range of train velocities and wheel diameters, only the general shape of signals remains sufficiently constant to be recognized.
