Rail car underframe assembly and modular car body for a rail vehicle

摘要

A rail vehicle car body includes two end modules (14), at least one of which is provided with a lateral access door, and a tubular module (18) extending from one of the two end modules to the other and mechanically fastened to the two end modules. The tubular module comprises a doorless shell made of longitudinal aluminium alloy extruded profiles extending from one of the two end modules to the other and longitudinally welded together. With such a structure, the interior outfit of the rail car can be installed through one of the open ends of the tubular module, after the longitudinal profiles of the shell have been welded together and painted. Similarly, refurbishment is simplified, since one of the end modules can be removed to give access to the interior of the tubular module.
