The interior system 22 includes interior facilities and interior structure.

[0079] In this embodiment, the in-vehicle facilities include a lounge 221, a restroom 222, and a corridor 223. The lounge 221 is located near the cargo area 3, and a window is provided on its side wall. The restroom 222 is located between the lounge 221 and the corridor 223. A lounge door 2210 connects the restroom 222 and the lounge 221, and a corridor door 2230 connects the restroom 222 and the corridor 223. The corridor 223 is located between the restroom 222 and the end wall 14, and a living / working area entrance / exit door 20 is provided on the side wall of the corridor 223. End doors 200 are respectively provided on the end walls 14 at both ends of the vehicle body 1.

[0080] In this embodiment, the interior structure includes a floor, a ceiling, partitions, and wall panels (all not shown). The floor is located above the base unit 11 and includes a resilient floor, an aluminum honeycomb panel, and a rubber pad. The resilient floor is located on the aluminum honeycomb panel, the aluminum honeycomb panel is located on the rubber pad, and the rubber pad is located on the steel plate of the base unit 11.
