The invention discloses a train automatic-parking executing system which comprises a servo motor, a driving beam, a driven beam, a turnout control relay, a trolley, a turnout structure with magnetic levitation plates and a turnout controller. The turnout structure with the magnetic levitation plates is arranged on the driven beam. The servo motor is mounted under the driving beam and connected with the trolley, the turnout control relay and the turnout controller. The driving beam and the driven beam are mechanically connected. The servo motor drives the trolley to drive the driven beam, underthe action of the driven beam, the turnout structure with the magnetic levitation plates, the driven beam and the driving beam are moved to a set rail as a whole, and thus a train runs to the set rail. An existing magnetic levitation rail structure is improved, levitating magnets are arranged in groove structures, airflow resistance is reduced, energy consumption of the magnetically levitated train is lowered, the safety guarantee capacity of magnetic levitation traffic is enhanced, and riding of magnetic levitation traffic is more quiet and comfortable.
