The invention relates to a vehicle operation piston effect exhaust vacuum pumping arrangement for evacuated tube transportation. The vehicle operation piston effect exhaust vacuum pumping arrangement for the evacuated tube transportation comprises a pipeline and a vehicle which is arranged in the pipeline, wherein a piston is arranged at the front end of the vehicle; the piston is fixedly connected with the front end of the vehicle through a connecting rod; the shape of the piston is matched with the interior contour of the pipeline; openings are formed in the wall of the pipeline at intervals of a certain distance and one-way valves are additionally mounted in the openings; and the one-way valves can be only opened towards outside of the pipeline. As the front end of the vehicle is connected with the piston, gas is exhausted out of the pipeline so that the operation cost is effectively reduced and economic benefits are increased.
