A rail grinder is a piece of equipment used to improve the condition of railway tracks by smoothing and reshaping the surface of the rails. Over time, rails can become worn, uneven, or damaged from constant train traffic. A rail grinder uses rotating grinding stones to remove small amounts of metal from the rail surface, restoring its smoothness and ensuring proper contact between the train wheels and the tracks. This helps to reduce noise, improve the ride quality, prevent further wear, and extend the life of the tracks. Rail grinders are an important part of track maintenance for maintaining safety and efficiency.
