According to the present invention, curved plates (6-8) for a railroad vehicle structure comprise: curve-shaped plate main bodies (11, 30, 40), each having an outer surface facing out from the vehicle and an inner surface facing into the vehicle; and reinforcing ribs (12-17, 31-36, 41-48) protruding toward the inside of the vehicle from the inner surfaces (11b, 30b, 40b) of the plate main bodies (11, 30, 40). The reinforcing ribs (12-17, 31-36, 41-48) have machining reference surfaces (A1, A2, A3) disposed in the same plane and formed as reference surfaces for the process of mechanically machining the outer surfaces (11a, 30a, 40a) of the plate main bodies (11, 30, 40). The reinforcing ribs (12, 15, 31, 35, 42, 43, 48) have attachment reference surfaces (X1, Y1, Z1, X2, Y2, Z2, X3, Y3, Z3) as reference surfaces for the process of attaching the reinforcing ribs to the vehicle, the attachment reference surfaces being orthogonal to the rail direction, the railroad tie direction, or the vertical direction.
