According to a railcar, a low-floor underframe includes side beams to which side bodyshells are coupled, a high-floor underframe includes a center sill disposed to extend in a car longitudinal direction at a center in a car width direction and a body bolster coupled to this center sill and to be an installation portion of a bogie, and the body bolster is coupled to the side beam by a coupling member. Thus, the car end compression load input to the high-floor underframe can be directly transmitted from the center sill and the body bolster to the side beams via the coupling member. This can disperse the car end compression load on the side bodyshells to ensure the car strength against the car end compression load.
