Abstract: A railway traction vehicle comprising a plurality of axles, a fuel gas power unit (112), a fuel gas storage assembly (118) including a predetermined number of fuel gas storage modules (122), and a fuel gas delivery network (120). The fuel gas storage assembly (118) comprises a plurality of identical fuel gas storage module receiving devices (124), and, for each of said receiving devices, an identical fuel gas coupling (126) for coupling a module (122) with said network (120). The modules (122) share a standardised configuration such that each of them can be received in any of said receiving devices (124) and coupled to the corresponding fuel gas coupling (126). They are distributed over said fuel gas storage module receiving devices (124) such that the load on the axles is optimised. The predetermined number is adapted to the amount of fuel gas needed by the vehicle to operate on a predetermined railway line. Preferred application to regional passenger multiple units.

Abstract: A device for connecting rail vehicles formed of a plurality of interconnected first and second car parts having a rotary joint with a swiveling crown, includes a rotary-restraint device provided in the joint region between each two car parts. The rotary-restraint device includes two sliding bodies disposed at the periphery of the swiveling crown of the rotary joint. The sliding bodies interact with one another in a frictionally engaged manner and are each fastened to one of the two car parts connected in the rotary joint.
