The invention discloses a shuttle vehicle of a high-speed rail fast transportation mode and mainly used for passengers of high-speed rail transportation. The shuttle vehicle mainly comprises a shuttlecarriage A, a shuttle carriage B, a balance arm, a pulley A, a pulley B, a pulley C, a pulley D, a steel wire rope, an electromagnet suction cup A and an electromagnet suction cup B. The main workingprinciple of the shuttle vehicle comprises allowing passengers about to get on an electric multiple unit (EMU) to enter a passenger carriage A of the shuttle vehicle in advance to wait and allowing passengers about to get off the EMU to enter a passenger carriage B of the EMU in advance to wait before the passengers get on or off the EMU, simultaneously electrifying a plurality of electromagnetsA of the shuttle vehicle and a plurality of electromagnets B of the EMU when the EMU enters a suspension system from the right side at high speed, accelerating the shuttle vehicle from a stop state toa state of speed synchronization with the EMU under the driving of the EMU, lowering the passenger carriage A into a transition carriage A of the EMU by virtue of the balance arm, and raising the passenger carriage B into the shuttle carriage B of the shuttle vehicle at the same time to complete the exchange work of the passengers getting on or off the EMU.
