A rail grinder is a specialized railroad maintenance vehicle that uses rotating grinding stones to remove material from train tracks, restoring the rail's "profile" and smoothness to eliminate defects and wear. This process extends the life of the tracks, reduces train noise, improves ride quality, and enhances safety by preventing cracks from developing into more serious problems.
