A collision energy absorption column is provided on an end side of a railroad vehicle structure and extends from an end beam toward a roof structure. The collision energy absorption column includes a metal outer member having a transverse cross section of a channel shape, and an inner member made of reinforced plastic provided along an inner circumference of the outer member and extending in parallel with the outer member. The outer member is configured by joining two column halves extending along a column axis after arranging the two column halves are arranged in a direction perpendicular to the column axis of the outer member. The joined part of the column halves extends along the column axis. The outer member is coupled to the end beam and roof by a fastener. The inner member extends between the end beam and a part of the roof structure, excluding the fastening parts.
