The article focuses on the preventive rail grinding policy launched by Deutsche Bahn (DB) which aims to extend rail life to minimize life-cycle costs in Germany. DB adopted a regular grinding cycle for tangent track and large radius curves which aims to achieve a rail life of 40 years. The strategy includes initial grinding of new rails and flaw removal on the other rails and cyclical grinding on high-density suburban lines.
