Track vibration damping device

The invention relates to the technical field of rail transit vibration isolation, and discloses a track vibration damping device. The track vibration damping device includes a vibration damping unit mounted between two adjacent fasteners of the rail, the vibration damping unit comprises a counterweight and an elastomer, wherein the elastomer comprises an elastic base connected to the rail waist ofthe rail and an elastic extension connected to the elastic base and extending toward a side away from the rail waist; the elastic extension and/or the elastic base are provided with a plurality of mounting holes into which the counterweight blocks are inserted, and the centerline of the mounting holes is parallel to the longitudinal direction of the rails. The track vibration damping device provided by the invention is characterized in that a vibration damping unit is arranged on the rail waist of the rail, the vibration damping unit comprises an elastomer and a counterweight connected with the elastomer, so as to ad
