A car body for a passenger rail vehicle includes a chassis having a front assembly at each vehicle end and a vehicle floor consisting of profiled metal sheet edged in a trapezoidal-like manner within the cross-section, wherein beads of the profiled metal sheet extend in a longitudinal direction of the car body, where the vehicle floor is fixedly connected to each front assembly at transition points to the front assembly via a connecting beam oriented transversely to the longitudinal direction of the car body, where the connecting beam is formed as a profiled metal sheet having a substantially L-shaped cross-section, and where the section of the connecting beam connected to a front assembly is equipped with a trapezoidal-like bead.

An electric rail carriage is described. The electric rail carriage may include a train carriage. The train carriage may be arranged to be powered by at least one power module, which is arranged to generate electric power. The carriage may include a main chassis, and at least one power module bay located underneath the main chassis. A power module can be removably located and secured within the power module bay, such that the power module is supported underneath the main chassis. A method of installing the power module into a power module bay is described.

A device for converting a diesel-electric locomotive into an electric locomotive includes operating components for an electric locomotive and an adapter frame on which the operating components are mounted. The adapter frame is designed so that it can be connected to connection points of a mechanical basic structure of the diesel-electric locomotive. There is also described a corresponding electric locomotive and a method for conversion.

A loss-prevention system includes a securing element securing components of a vehicle or rail vehicle and having a first portion and first and second lugs. The first portion is an elongate plate extending in a first plane. A first through-passage opening is disposed in the first portion. The first through-passage opening accommodates at least part of a first releasable connection for fastening the securing element on a first component. The first portion has a long side. The first and second lugs are disposed on the long side of the first portion, or opposite one another, and project from the first plane onto a common side of the first portion. The first lug is configured to rest on the upper side of the first component. The second lug is configured to support a second component on its underside and to secure the same against falling off.

A carbody of a railcar includes an underframe, a side bodyshell, and a roof bodyshell. At least one of the underframe, the side bodyshell, and the roof bodyshell includes: an outer plate portion facing a car outside; and a reinforced portion joined to an inside surface of the outer plate portion and forming at least one internal space between the reinforced portion and the outer plate portion. At least one sound absorbing hole communicating with the internal space is formed on the outer plate portion.
