A linear propulsion assembly imparts a force upon an elevator car in a hoistway, and includes primary and second portions, and an active damper system. The primary portion mounts to one of the car and the hoistway, and includes a plurality of electric coils. The secondary portion mounts to the other of the car and the hoistway, and includes a rail and a plurality of magnets engaged to the rail for moving the secondary portion with respect to the primary portion. The active damper system is in contact with the rail for damping rail vibration. The rail includes a first side through which the plurality of magnets are exposed, and an opposite second side engaged to the active damper system.
