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.

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.

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.

A carbody of a railcar includes: a roof bodyshell; a supporting body provided under the roof bodyshell, the supporting body being attached to the roof bodyshell in a state of being positioned in the vertical direction; a rotating body which is threadedly engaged with the supporting body and rotates relative to the supporting body about an axis extending in a vertical direction to be displaced relative to the supporting body in the vertical direction; and a support target member supported by the roof bodyshell through the supporting body and the rotating body, the support target member being attached to the rotating body in a state of being positioned in the vertical direction, a vertical distance between the roof bodyshell and the support target member being adjustable by displacement of the rotating body relative to the supporting body.

A method for modular manufacturing of a car body shell of a rail vehicle includes manufacturing at least two directly adjoining large assemblies of the car body shell in parallel. The large assemblies are selected from among the group including an underframe, a side wall, a roof, an end wall, and a head of the body. The at least two large assemblies manufactured in parallel as described above are joined by structural adhesive bonding. A car body shell of a rail vehicle manufactured by the method is also provided.

The invention relates to a head module for a rail vehicle, said head module being suitable to be detachably fixed to the front face of a subsequent railcar unit without additional underframe. The head module consists of an inner and an outer shell and includes three systems which convert, in the event of a crash, the collision energy into a deformation one after the other or simultaneously and substantially independently of another.

A car body has at least: two lateral walls, each of which is made of a lower and upper longitudinal member that are connected by multiple lateral wall segments and vertically arranged columns, a roof, a base, two end walls or one end wall, and a head module, wherein the lower longitudinal members of the two lateral walls are connected to the base by means of connection elements in the longitudinal direction of the car body, and the upper longitudinal members of the two lateral walls are connected to the roof by means of connection elements in the longitudinal direction of the car body. The lower and upper longitudinal members are designed as multichamber hollow profiled sections which are continuous over the entire length of the car body, the lower and upper longitudinal members are made of fiber-reinforced plastic, and the connection elements at least partly consist of metal.

A railcar that allows a first end beam to move toward a second end beam when an intended load is input is provided. A railcar includes a fuse member that couples a first end beam to a second end beam along a car longitudinal direction, and the fuse member buckles when a load received in collision exceeds a predetermined value to allow the first end beam to move toward the second end beam, thus ensuring reduction of variation of the load that allows the first end beam to move toward the second end beam. Consequently, when the intended load is input, the first end beam is allowed to move toward the second end beam.

A method of assembling a body of a rail vehicle includes steps of: creating a numerical model of at least one specific module; dimensioning in the numerical model, the position of fixing holes in the specific module, the dimensioning of each fixing hole being defined at least with respect to one edge of the specific module extending in a direction of greater length of the specific module and with respect to an axis transverse to the longer direction; supplying the specific module; drilling the fixing holes in the specific module by a drilling device at the position listed in the numerical model; and assembling the body, the assembly including attaching the specific module to at least one adjacent module utilizing a fixing unit inserted into the fixing holes drilled in the specific module.
