The invention relates to a machine for stabilizing a track, including a machine frame supported on on-track undercarriages and a vertically adjustable stabilizing unit designed to roll on rails of the track by means of unit rollers, the stabilizing unit comprising a vibration exciter with rotating imbalance masses for generating an impact force (FS) acting dynamically in a track plane perpendicularly to a track longitudinal direction and a vertical drive for generating a vertical load acting on the track. In this, it is provided that the vibration exciter comprises at least two imbalance masses which are driven applying a variably adjustable phase shift (Δϕ1, Δϕ2). The invention further relates to a method for operating such a machine.
