A floor structure is provided with an underframe, which is part of a carriage body, is elongated along a longitudinal axis coinciding with the advancement axis of such carriage, and has a plurality of longitudinal attachment rails arranged on an area of the lower surface of the underframe; the attachment rails project downwards so as to define therebetween a plurality of compartments, which are engaged by panels having insulating material to form a fire protection system; such a system has, furthermore, a plurality of section bars, which are attached to the attachment rails and are shaped so as to retain the panels in fixed positions in the compartments and, at the same time, cover the attachment rails.

A solebar for a railway vehicle has an elongate body that comprises a first leg and a second leg, wherein the first leg and second are configured to meet at a vertex and have an obtuse angle therebetween such that the solebar has an obtuse L-shaped cross-sectional profile. The solebar is mounted as an underframe side member in a railway vehicle such that the first leg extends in a downwardly direction towards a floor supporting the railway vehicle and clears a lower sector of a loading gauge, and the second leg inclines upwardly in a direction away from railway vehicle and clears an upper sector of the loading gauge. The second leg is configured to support an upper sidewall of a body of the railway vehicle such that the upper sidewall clears the upper sector of the loading gauge.

A railcar includes: an underframe including a pair of side sills located at both respective ends of the underframe in a car width direction and extending in a car longitudinal direction and a plurality of cross beams coupling the pair of side sills to each other in a car width direction; and an underfloor cover covering an underfloor portion of the underframe. The underfloor cover includes upper and lower plate-shaped members (a shielding plate and a closing plate) made of stainless steel, and the upper and lower plate-shaped members are at least partially spaced apart from each other.

The present invention relates to a container assembly comprising a container, and a load bearing exoskeleton for the container, the exoskeleton comprising a space frame construction. Also disclosed are a vehicle trailer, a rail wagon, and dump body for a dump truck comprising the container assembly.

An attaching metal fitting is used to attach an underfloor device to an underframe of a railcar including a beam member and includes: a first member located at a lower side of a projecting portion projecting in a horizontal direction at a lower end portion of the beam member and formed integrally with or separately from the beam member; and a second member located at an upper side of the projecting portion, wherein: the first member includes a first supporting portion overlapping the projecting portion from below to be fixed to the projecting portion; the second member includes a second supporting portion overlapping the projecting portion from above to be fixed to the projecting portion; and an upper surface of the second supporting portion supports the underfloor device with the projecting portion sandwiched between the first supporting portion and the second supporting portion.

A method for producing a porous metal foil comprising causing a metal foil together with a soft sheet to pass through a gap between a pattern roll of a hard metal, which has high-hardness, fine particles having particle sizes of 50-500 m on the surface, and a hard metal roll opposing the pattern roll, to press the metal foil and the soft sheet, thereby forming fine pores in the metal foil; the soft sheet being a laminate sheet of a relatively hard plastic layer and a relatively soft plastic layer; and the pressing of the metal foil being conducted with the relatively hard plastic layer on the side of the metal foil, and the relatively soft plastic layer on the side of the hard metal roll.

A railcar includes: an underframe including a pair of side sills and a plurality of cross beams each connected to the pair of side sills, the cross beams being arranged at intervals in a car longitudinal direction; and a floor pan arranged in a space surrounded by the pair of side sills and a pair of adjacent cross beams among the plurality of cross beams, the floor pan being fixed to the underframe, the floor pan being configured as a strength member configured to bear at least one of a compressive load and shearing load applied from the underframe.
