Grinding the rails only helps against roughness of the upper surface of the rail (which causes a "roaring" noise - https://en.wikipedia.org/wiki/Railgrinder#Rail_corrugation https://en.wikipedia.org/wiki/Railgrinder#Rail_corrugation). The most annoying noise in my experience is the screeching noise when going around curves (or on badly maintained straight tracks) - this can best be solved by using flange lubrication (https://centrallubrication.com/en/lubrication-techniques/wheel-flange-lubrication.php https://centrallubrication.com/en/lubrication-techniques/whe...).
