    摘要： Provided is a rail vehicle that can promote a weight reduction of the rail vehicle by providing a film body in a side film or a ceiling film, can ensure a large vehicle inner space, can prevent the occurrence of stains, scratches, and the like. The rail vehicle includes an underframe including a floor portion, side structures that each have a window and are erected along a longitudinal direction of the side structures at both end portions in a width direction of the underframe, and side films provided along surfaces of the side structures on a vehicle inner side. Each of the side films has a window opening portion at a portion corresponding to the window, and a window frame portion that presses a peripheral edge portion of the window opening portion toward the side structure is provided.

    摘要： 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.
