A rail vehicle includes a roof structure that configures an upper face, a side structure that configures a side face, a gable end structure that configures an end face in a longitudinal direction, and an underframe that configures a lower face. The underframe is configured from a hollow shaped member formed from two face plates and a rib that connects the face plates to each other. The hollow member that configures the underframe includes a first upper side face plate arranged at a central portion in a widthwise direction of the underframe, a first lower side face plate arranged at the central portion in the widthwise direction of the underframe, a second upper side face plate arranged at an end portion in the widthwise direction of the underframe and positioned below the first upper side plate, a second lower side face plate arranged at the end portion in the widthwise direction of the underframe and positioned below the first lower side face plate, a third upper side face plate that connects the first upper side plate and the second upper side plate to each other, and a third lower side face plate that connects the first lower side face plate and the second lower side face plate to each other. A space is provided below the first lower side face plate, and a closing plate that connects adjacent end portions of a pair of the second lower side face plates to each other is arranged in the space.

The present invention addresses the problem of providing a method for molding, using a honeycomb core, a composite material structure that is high-quality, low cost, and leaves less voids. The present disclosure addresses the problem of providing a method for molding, using a honeycomb core, a composite material structure with which it is possible to reduce dimples in a composite material skin at low cost. According to a method for molding a composite material structure of the present disclosure, an uncured composite material honeycomb sandwich panel in which prepreg is laminated on upper and lower surfaces of a honeycomb core via an adhesive is covered with a vacuum bag and placed in an autoclave. After that, the vacuum bag is evacuated and, while the evacuation is being continued, is heated and pressurized by the autoclave to cure a matrix resin of the prepreg and achieve adhesion to the honeycomb core.

A floor panel (100) for transport means, in particular for trains, ships or boats, the floor panel (100) comprising a metal plate (1); at least one heating cable (2, 3) adapted to generate heat when it is crossed by electric current; a net (4) provided with a plurality of meshes (41); wherein said at least one heating cable (2, 3) is arranged between the net (4) and the metal plate (1). wherein said at least one heating cable (2, 3) is in contact with the metal plate (1).

A railcar floor structure includes: a plurality of floor panels arranged over an entire length of a passenger room of a railcar in a car longitudinal direction and including respective electric heaters; a wiring duct extending in the car longitudinal direction and arranged between a side bodyshell and car width direction end portions of the floor panels; an electricity supply cable arranged at the wiring duct, electric power being supplied to the electric heaters through the electricity supply cable; and a wire insertion opening formed at a side wall portion of the wiring duct, the side wall portion being located close to the floor panels and extending along the car longitudinal direction, the electricity supply cable passing through the wire insertion opening.

A railway vehicle car includes a lower level and an upper level that are separated by an intermediate floor. The intermediate floor defines an opening emerging on the upper level and on the lower level, and also defines a bridge extending at least partially along the opening. The bridge connects a first longitudinal end and a second longitudinal end of the car on the upper level. The circulation of passengers is blocked on the lower level at least at one of the first and second longitudinal ends. The car provides for dining for travelers. The lower level includes a preparation area and a dining area, with the preparation area extending continuously between a first side wall and a second side wall of the car, over an entire width of the lower level.

A railroad tank car may have external fittings, such as brake fittings. A low mount brake fitting is located in a recess formed in the end sill of the car or in the side sill of the car between the main bolster and the end sill. Where an end sill installation is used, the end sill may be asymmetric, with the recess being formed to one side of the center sill. Alternatively, the end sill may be offset longitudinally away from the striker, and a spacer inserted.
