摘要： A double-track vehicle, comprising upper and lower carriages, which are respectively a passenger carriage (1) for providing passenger seats and a cargo carriage (2) for placing cargo, the passenger carriage (1) and the cargo carriage (2) being respectively provided with a passenger door (3) for passengers to get on and off and a cargo door (4) for loading and unloading cargo. The vehicle carries out simultaneous transport of passengers and cargo, allowing for the function of the rail vehicle to no longer be singular and largely reducing transport and maintenance costs. At the same time, passenger transport and cargo transport are divided into two layers, which completely separates cargo transport and passenger transport, thereby providing passengers with a comfortable seating environment and improving seating safety.
