The present invention relates to a method and a combined-propulsion system for high-speed vehicles, which comprises a closed tubular guiding structure and a vehicle designed to move through the inside of the tubular structure, the system comprising: a vacuum system coupled to the tubular structure to provide a safe atmosphere at low pressure, always above the Armstrong limit; electric propulsion means arranged in an initial section of the structure, to accelerate the vehicle to a determined cruising speed; and compressed-air propulsion means arranged on the vehicle, to maintain the cruising speed.
