According to some embodiments, a railcar extension for extending the width of a railcar comprises: a top portion for attaching to a railcar support; a first side portion coupled to the top portion, the first side portion comprising two parallel transverse walls connected by a longitudinal wall all extending perpendicular from the top portion and the two transverse walls are for attaching to the railcar support; a second side portion coupled to the first side portion, the second side portion comprising two parallel transverse walls connected by a longitudinal wall all extending downward from the first side portion and the two transverse walls are for attaching to the railcar support, and wherein the second side portion pivots with respect to the first side portion to conform to the railcar support; and a bottom portion coupled to the second side portion, the bottom portion for attaching to the railcar support.

A double-deck rail vehicle and a vehicle body thereof are provided. An underframe (11) of the vehicle body comprises a lower-layer underframe (111), end underframes (112, 115), sealing plates (114, 116), and side underframes (118, 119); wherein the lower-layer underframe is provided with an underframe middle beam (1111); the end underframe is fixedly connected to the underframe middle beam by means of reinforcement middle beams (113, 117); the sealing plate is fixedly connected between the end underframe and the lower-layer underframe; and the side underframe comprises side beams (1181, 1191) of the side underframe that are integrated, and the side underframe is fixedly connected to the end underframe by means of the side beams of the side underframe. The vehicle body supplements the reinforcement middle beams capable of increasing the connection strength between the end underframe and the lower-layer underframe, and uses the integrated side beams of the side underframe. Therefore, the structure strength, rigidity and compression-resistant performance of the vehicle body can be enhanced, so that the safety of the double-deck rail vehicle can be improved, and a problem that a related double-deck vehicle body does not satisfy the requirements of America strength standard can be solved.

A railroad car including a plurality of penetration resistant and protective structures including a penetration resistant and protective underframe, penetration resistant and protective first end, second end, and center bulkheads, penetration resistant and protective first, second, third, and fourth side walls, and protective first and second roof hatches, all configured to protect internal cylinder assemblies, the pipes that communicate the gas from the cylinders of the cylinder assemblies, and the safety critical valves, regulators, and other equipment connected to such cylinders and pipes of the railroad car in an accident (such as a derailment, crash and/or roll-over).

The present invention provides a rail vehicle. The rail vehicle includes: an underframe assembly, a side wall assembly, a vehicle roof assembly, and a vehicle end assembly. The underframe assembly includes a primary energy absorption structure and an underframe edge beam which are connected. The primary energy absorption structure has at least two energy absorbing cavities that are set at interval. The lower end of the side wall assembly is connected with the underframe assembly. The upper end of the side wall assembly is connected with the vehicle roof assembly. The vehicle end assembly includes an end energy absorption structure whose lower end is connected with the primary energy absorption structure, and upper end is connected with the vehicle roof assembly. By using the technical solution of the present invention, that is, the primary energy absorption structure of the underframe assembly, the vehicle roof assembly, and the end energy absorption structure which is installed between the vehicle roof assembly and the primary energy absorption structure form the overall energy absorbing structure at the end of the vehicle body structure, there is no need to add an independent energy absorbing component. The present invention improves impact energy absorbing performance of the vehicle without increasing the overall dimension of the vehicle body structure.
