Abstract
A railcar includes an underframe and an energy absorber provided at the underframe. The underframe includes a first end beam, a second end beam, and a sliding center sill connecting the first end beam and the second end beam with each other. The sliding center sill includes a first beam member connected to the first end beam, a second beam member connected to the second end beam, and a coupling member coupling the first beam member to the second beam member. The first beam member slides relative to the second beam member when the coupling member breaks by application of an impact load higher than a predetermined load. The sliding center sill and the energy absorber are arranged in a region located between the first end beam and the second end beam.
