This paper investigates a high speed vacuum tube train system relying on wheels for suspension and a multi-mode linear electric machine for charging and propulsion: the machine will be configured as a doubly fed induction machine for charging at stationary, and as a permanent magnet synchronous machine for acceleration and deceleration. The system configuration is first presented, then a linear doubly fed induction machine which can be used for charging at stations is designed and optimized based on genetic algorithm. The design is also validated by finite element modelling. Afterwards, a 1275 km long journey between Damman and Jeddah through Riyadh in Saudi Arabia is selected to demonstrate the application of the presented system.
