The invention relates to the technical field of rail traffics, in particular to a low-noise damping rail. The low-noise damping rail comprises rail bodies and a fixing plate, wherein the top end of each rail body is fixedly connected with a top plate; the bottom end of each top plate is fixedly connected with a supporting plate; one side of each supporting plate is fixedly connected with the corresponding rail body; the inner side of each supporting plate is fixedly connected with a sleeve; the inner side of each sleeve is in sleeve connection with a telescopic tube; the bottom end of each telescopic tube is fixedly connected with a fixing plate; one end of each fixing plate is fixedly connected with a spring; a partition is arranged at the bottom end of each fixing plate; a silencing holeis formed in the inner side of each partition; the bottom end of each fixing plate is fixedly connected with a connecting plate; the bottom end of each connecting plate is fixedly connected with a bottom plate; a fixing block is arranged between the rail bodies; a connecting hole is formed in the outer side of the fixing block; and the top end of the fixing block is fixedly connected with a connecting plate. Noises generated by a train and vibration generated by collision of carriages are reduced. The low-noise damping rail has huge economic benefit and extensive market prospect, and is worthy of being popularized and used.
