The invention discloses a lightweight intercity motor train unit body, which comprises an underframe assembly and a side wall assembly, wherein the bottom frame assembly comprises a floor formed by assembling and welding aluminum profiles and edge beams of the aluminum profiles. The floor is integrated with a C-shaped groove at the equipment position below the hoisting vehicle; under-vehicle equipment for hoisting, the edge beams are welded to the two sides of the floor. A sleeper beam installation beam with an installation connector is arranged in the area, connected with the bogie, of the boundary beam; the installation connector is used for being connected with the modular bogie; an ultra-wide doorway is arranged on each side of the side wall assembly; a door frame is installed on eachdoorway and formed by connecting closed profiles; the strength of the door frame profiles is higher than that of the side wall profiles, so that local rigidity and strength of the doorways are guaranteed. The motor train unit body has advantages of simple structure, light weight, reduced raw material cost, increased passenger capacity and reduced energy consumption.. Rapid overhaul, maintenance and overall replacement can be achieved, and the whole line transportation capacity of the motor train unit is improved. According to the invention, passengers can get on and off quickly, parking time is shortened, and high-density operation requirements can be met.
