An economical and technically feasible method for the transport of containerized cargo by means of an evacuated tubular system using hybrid propulsion drives is presented. A brief history is given of one of the propulsion drives, that of pneumatic thrust. The second drive component, that of electric motors, is discussed in the portion that describes the general operation of the hybrid propulsion evacuated tube system. The system utilizes the pneumatic thrust for the acceleration of the train to a selected cruising velocity, whereupon the electric motors take over to maintain the cruising velocity throughout the main guideway section of the route to the train's destination. An illustrative example of a specific train operation is developed that considers the tube dimensions, degrees of evacuation, train weight, acceleration phase and cruising speed. In conclusion, approximate costs for the system are estimated and extended mobility of the container-vehicle train units beyond the tubular terminals is mentioned.
