Disclosed is a carriage body for a multiple unit train, comprising: a chassis (10) and a power system module mounted in a suspended manner below the chassis (10), wherein an access opening (11) for facilitating to overhaul the power system module is provided on the chassis (10), and a floorboard (12) of a passenger compartment covers a top surface of the chassis (10) and surround the access opening (11), and further comprising an access door (2) used for blocking the access opening (11), the access door (2) comprising a top panel (21), a reinforcement panel (22), and a sound-insulation panel (23) for sound-proofing, which are provided successively from top to bottom, the top panel (21), the reinforcement panel (22) and the sound-insulation panel (23) being fixedly connected as one piece; the periphery of the top panel (21) engages with the floorboard (12) of the passenger compartment; and the top panel (21) is detachably yet fixedly connected onto the floorboard (12) of the passenger compartment and/or the chassis (10). The carriage body for a multiple unit train can be conveniently opened during maintenance, and not only can the access opening be reliably blocked during normal operation, but the bearing strength of the access door is also improved, the safety, sealing, and sound-proofing effects are good, and noise transmitted from the power system module to the passenger compartments can be effectively reduced.
