A new eddy current instrument in a rail grinding train

  • The recognition of surface damage on railway lines is of critical importance in order to guarantee a high level of safety for normal train operation. Without early recognition systems, defect damage (e.g. cracks) in the rail, will in most cases, increase in size and can eventually lead to fracture of the rail. Special grinding trains are in general use for rail maintenance and are employed to machine down worn rails and prevent surface damage in an early stadium. The company SPENO INTERNATIONAL SA along with the BAM and other partners have integrated an eddy current instrument in the grinding train. The equipment has been developed for detection of Head Check type defects and provides information on defect position and depth. Initial experiments were presented at the DACH-conference 2004 in Salzburg. This system has been continually developed and as will be shown is ready for practical application. The main characteristics of this system are: - 4 channel measurement per rail. -The recognition of surface damage on railway lines is of critical importance in order to guarantee a high level of safety for normal train operation.
