· THE RAIL GRINDING INTERVAL AND METAL REMOVAL Even more contentious than rail shape are the issues of how often to grind rail and how much metal to remove at each cycle. Although there is a consensus that grinding does extend rail life the trade off between the cost of frequent grinding and the increase in rail life is often debated. The current best practice has evolved over a .
