Ziv-Av’s dedicated Failure-Analysis Saves Huge asset of Israel’s National Railways

Israel Railway discovered repeating cracks in passenger trainsets. The cracks appeared in specific recurring locations in the coaches. Ziv Av was approached to investigate the reason for these cracks, and to provide a solution that will allow the fleet to continue operation.



Ziv-Av performed a comprehensive study of the load regime acting on the coach body, 3D modeling and FEA of the relevant fuselage area, and supplied the root cause of these cracks. The investigation concluded that these cracks do not pose a safety risk and that the trainsets can continue their service while a repair plan is in progress, saving Israel Railways a lot of time, effort and expense.

Having located the root cause of the cracks,, Ziv-Av started work on designing a solution that would prevent the cracks from propagating, strengthen the surrounding area and be simple and cost effective in terms of execution costs.
Ziv-Av’s team devised a complete process of retrofitted repair with QA gates of approval along the different stages of the repair and trained local personnel to perform this task for the rest of the fleet
