A gondola car has a body for lading carried on an underframe. The underframe includes a center sill and cross-bearers. The car has deep side beams having top chords, side sills, and side sheets. The lower portion of the car includes tubs that seat between the cross-bearers. The car may have an internal volume of more than 8000 cu. ft. The car may have rotary dump claw sockets. The car has opposed internal and external stiffeners aligned at the longitudinal stations of the cross-bearers. The internal stiffeners may be triangular cantilevers extending upwardly inside the side sheets. The side sheet lies intermediate the stiffeners and their flanges. The top chords may be wider in cross-section than the side sills. The side sills may define torque tubes that co-operate with the sidewall stiffeners and the top chords to resist lateral deflection. The car may include a false deck, or dog-house at one end to accommodate the brake reservoir and brake valve, such that the car is longitudinally asymmetric.

A component fastening structure has a first component and a second component connected by a bolt and a nut. The first component includes a through hole through which a bolt is inserted, a seating face on which the bolt head is mounted near an upper end opening of the through hole, two rotation preventing wall portions which are formed near the seating face at both sides of the head to position the head between them, and lifting suppressing portions which are formed at positions apart above the seating face on the individual rotation preventing wall portions and protruded toward the head side. The interval between the two rotation preventing wall portions is smaller than the distance between the tip ends of two arm parts formed on the bolt head, and the seating face sides of the lifting suppressing portions are opposed to the upper surfaces of the arm parts.

A layered building element for protecting exterior or interior building surfaces is disclosed. Exterior or interior surfaces may include both vertical and horizontal surfaces, such as walls, roofs, or floors. The layered building element includes a flexible sheet comprising at least one elastomer layer in communication with an elastomer-impregnated fiberglass layer. Each elastomer layer may be bound in communication to the fiberglass layer at an interface comprising elastomer-impregnated fiberglass. The flexible sheet may form, for example, shingles, tiles, or a cylindrical roll, which may support portability and installation of the layered building element.

An improved reefer wall panel having better foam adhesion includes purposefully spaced gaps in the looped sections to be foamed. Such spaced gaps may extend horizontally, vertically, diagonally or in combinations of directions. These gaps (random or patterned) may be applied to the whole of a reefer panel or to just the more vulnerable lower sections where traffic impact during loading/unloading is more common and/or where delamination is known to occur more frequently. A method of reefer panel manufacture with such spaced gaps is also disclosed.

The present invention relates to an equipment envelope (10) for a hopper wagon. The equipment envelope comprises a housing (11) that is configured to define an enclosed cavity storage space (12) in a bulk commodities storage chamber of a hopper wagon body, in which hopper wagon control means and/or other component parts of the hopper wagon (30) can be housed for use. The equipment envelope may be configured to be arranged in the chamber such that it is located above a hopper wagon bogie (40), preferably adjacent a closable outlet. The equipment envelope may comprise a first end wall (111) that is configured to extend at a predetermined incline angle towards the outlet. Depending on the configuration of the hopper wagon, the equipment housing may be configured to be located adjacent a further or alternative closable outlet. The equipment envelope may comprise a second end wall (112) that is configured to extend at a predetermined incline angle towards the further outlet. The first end wall and second end may be configured to meet at an apex (14) such that the equipment envelope has a cross-sectional profile of a triangle, preferably a scalene triangle. A further aspect of the present invention relates to a hopper wagon comprising at least one equipment envelope.

A large component for a rail vehicle includes a grid structure of bows and ribs, and paneling formed from the grid structure, where the ribs are formed as planar sheet metal parts that are butt-welded to the paneling, and the bows are configured as planar sheet metal parts that are butt-welded to the paneling, and where a C-rail is arranged on at least one of the bows.

According to some embodiments, a system may include an additive manufacturing platform that provides additive manufacturing capability data. A customer platform, associated with a customer, may transmit an industrial asset item request for an industrial asset item. A digital transaction engine may receive the additive manufacturing capability data and the industrial asset item request. The digital transaction engine may then associate the industrial asset item request with an industrial asset definition file, and, based on the additive manufacturing capability data and the industrial asset definition file, assign the industrial asset item request to the additive manufacturing platform. The assignment of the industrial asset item request may be recorded via a secure, distributed transaction ledger. Responsive to the assignment, the additive manufacturing platform may create the industrial asset item (e.g., via an additive manufacturing printer) and provide the item to the customer.
