A floor section for an insulated railcar includes a floor plate and a composite section coupled to the floor plate. The composite section includes a plurality of composite beams aligned parallel to one another. Each composite beam of the plurality of composite beams includes an inner core and an outer material surrounding the inner core. The inner core includes an insulating material and is configured to support the outer material. An upper surface of each composite beam of the plurality of composite beams, which extends along a length of the composite beam, is coupled to an underside of the floor plate.

A carbody of a railcar includes an underframe, a side bodyshell, and a roof bodyshell. At least one of the underframe, the side bodyshell, and the roof bodyshell includes: an outer plate portion facing a car outside; and a reinforced portion joined to an inside surface of the outer plate portion and forming at least one internal space between the reinforced portion and the outer plate portion. At least one sound absorbing hole communicating with the internal space is formed on the outer plate portion.
