The invention relates to a novel train device and belongs to the field of vehicles. The novel train device comprises an air compressor, an air storage tank, a pipeline, a wind turbine train, a screw column, a vacuum tank and a vacuum pump; the air compressor is connected with the air storage tank; the air storage tank is used for storing high pressure air exhausted by the air compressor; a track is mounted on the pipeline; the wind turbine train is arranged in the pipeline; the wind turbine train comprises a plant and a wind turbine; a bearing is connected between the plant and the wind turbine; a circular hole is formed in the center of the plant; the plant is designed in front of the wind turbine; three or more blades are arranged on the wind turbine; and a special hole is formed in thecenter of the wind turbine. A mechanical arm is mounted on the inner wall of the pipeline. The high pressure air enters into the pipeline, the wind turbine on the wind turbine train in the pipeline isdriven by the high pressure air to rotate and advance along a thread; the wind turbine drives the plant to advance. The wind turbine train is pushed to advance by using the high pressure air as power; therefore, the novel train device has the advantages that the the novel train device is efficient and the energy is clean.
