Disclosed is a railway vehicle body, the body including at least one floor module, at least one wall module and at least one roof module, the modules being connected to one another by rivets. The rivets include lower rivets connecting each wall module to the floor module, the lower rivets including at least one group of stiffening rivets including at least three stiffening rivets that are all arranged along a curve formed in a plane perpendicular to a transverse direction of the body, and having a first end with a first tangent and a second end with a second tangent, the first and second tangents forming an angle between them smaller than or equal to 90.

A rail vehicle, in particular a locomotive, includes a railcar body having a head end provided with a front nose. The railcar body has an interface, in the region of the head end, which is configured and provided for fastening and connecting differently shaped front noses forming a set of variations. A front nose selected from the set of variations is thereby fastened to the interface by a welded connection. The rail vehicle therefore permits more flexibility in the shaping of the head end of the railcar body.

A frame includes a first member having a side wall, and a second member having side walls. The first member has first through-holes. The side walls have slits inside which the first through-holes are unobstructed while the side wall is received in the slits, and locking portions that protrude and fit into the first through-holes.

Some embodiments of the present disclosure provide a roof component of a railway vehicle, and a railway vehicle. The roof component of a railway vehicle includes: two upper boundary beams, the two upper boundary beams being provided at an interval; a camber beam component, the camber beam component being provided between the two upper boundary beams; and a transitional structure, provided on the camber beam component, the transitional structure being connected with at least one of the two upper boundary beams. The technical solution of the present disclosure solves the problem in the conventional art of inconvenient connection between a camber beam component and an upper boundary beam, and a transitional structure of the present application facilitates processing and forming.

A process for manufacturing a base board of a high-speed rail equipment cabin using a composite material is disclosed. The composite material includes: aramid honeycomb, PET foam, 3K twill carbon fiber flame retardant prepreg, unidirectional carbon fiber flame retardant prepreg, glass fiber flame retardant prepreg, aramid flame retardant prepreg, and 300 g/cm.sup.2 single component medium temperature curing blue epoxy adhesive. The process includes manufacturing a base-board main plate (1), a base-board handle (2) and two base-board sliders (3). While installation, the base-board handle (2) is stuck to one side of the base-board main plate (1), and the two base-board sliders (3) are respectively stuck to another two opposite sides of the base-board main plate (1). The weight of the base board made from the composite material is 35%-40% lower than the base board made from the aluminum alloy material, which leads to a good prospect of application.

The railway vehicle comprises at least one end car, each arranged at a respective end of the railway vehicle, and, for each end car, a first car adjacent to this end car, and at least one second car, one of which is adjacent to the first car. Each second car comprises a second structural body. Each first car comprises a first structural body substantially identical to the second structural body of each second car, and a structural extension part attached on the first structural body and intended to be connected to the adjacent end car.

The invention relates to a work vehicle for carrying out work operations on a track, comprising a vehicle frame which can be moved on the track supported on rail running gears, a drive cab which is connected to the vehicle frame, and various mounted structures with assigned functions for a work operation. The mounted structures are designed as self-supporting function modules with predefined interfaces and connected to the vehicle frame and/or each other by means of threaded connections. The predefined interfaces enable the interconnection of different function modules without further adaptations. All modules are continuously checked with regard to their geometry and their functions to enable joinability in the final assembly without welding and adjustment processes.

A railcar bodyshell includes: a plurality of modules into which at least one of a floor portion, side portion, and roof portion of the bodyshell is divided in a car longitudinal direction; and an elongated member extending in the car longitudinal direction, the plurality of modules being attached to the elongated member. The elongated member includes a groove portion for fixing the plurality of modules to the elongated member the groove portion extending in the car longitudinal direction.
