摘要： Disclosed is a rail for a railroad, wherein the rail has a vibration absorbing assembly which can reduce vibration and noise generated when a railroad car driven on the railroad. According to the present invention, the rail for a railroad comprises a head part, a first and a second web part formed at both lower sides of the head part, and a first and a second flange part respectively, horizontally, and oppositely extended from the bottoms of the first and the second web part, wherein at least one of the web part has a surface on which a noise reducing assembly is fixed and mounted by multiple fixing clips. The noise reducing assembly used for the rail and supported to be fixed on the web part by the fixing clips comprises: a damping sheet adhering to the surface of the web part; a vibration absorbing body adhering to the outer surface of the damping sheet; a sound absorbing body positioned outside the vibration absorbing body; and a vibration damping steel sheet positioned outside the sound absorbing body. The fixing clip is an elastic clip made from a high elastic metal material, and partitioned into a first part corresponding to the web part, a second part corresponding to the lower side of the flange part, and a third part facing the first part and corresponding to the front end of the flange part. The first and the second part of the elastic clip form a certain angle so that an elastic force applied to the first part faces the second part, wherein the first part has a front end touching the vibration damping steel sheet which is the outermost member of the vibration absorbing assembly and a curved part formed at a boundary between the third part and the second part houses the side end of the flange part.
