For example, the distinction is made between the honor car and the ordinary car by changing the size of the seat, the front-back distance, the size of the window, and the like. One set of vehicles traveling long distances is configured by connecting these plural types of vehicles.

[0003] As for the body of a conventional railway car, a separate car body is designed and manufactured for each purpose of use, or Japanese Unexamined Patent Publication No.
As disclosed in Japanese Patent No. 6755, a vehicle suitable for each purpose of use is provided by using a common vehicle body and having a structure in which in-vehicle facilities such as a seat and a partition wall can be freely arranged.

[0004] On the other hand, in a railway vehicle running at a high speed, it is required to reduce the weight, improve the rigidity, and improve the strength of the vehicle body. From this viewpoint, it has been proposed to form a vehicle body by welding a brazed honeycomb panel made of a light alloy. The honeycomb panel has a core having a large number of hexagonal cells arranged between two face plates. In addition, a thick connecting member is disposed on an outer peripheral portion between the two face plates. The two face plates, the core and the connecting member are brazed to adjacent members to be integrated. The honeycomb panels are welded to each other at a joint member, and are welded to a bone (a pillar or the like) to manufacture one vehicle body. This vehicle body is disclosed in Japanese Patent Application Laid-Open No. 03-90468.

The plates of the honeycomb core 82 are arranged with their longitudinal direction in a direction (longitudinal direction of the vehicle) orthogonal to the direction of the arc of the mold. For this reason, since the plate is orthogonal to the curved surface of the arc-shaped face plate 81, the ends of the honeycomb core plate located inside in the radial direction are in contact with each other, and the outside ends are separated. If the distance between the separated portions is small, the ends are joined by a brazing material. Therefore, an arc-shaped panel can be obtained.

The pieces 83a and 83b of the connecting member 83 are welded to the adjacent laminated panel, the floor 30, the shoulder 65, the entrance / exit units 45A and 45B, etc. to form a vehicle body.

FIG. 14 and FIG. 15 show a private room vehicle, in which eight private rooms 90 are provided. The configuration of the side part 40 is the same as that of FIG.

As described above, the length of the laminated panel P1 and the like is set to be a multiple (integer) times the pitch of the windows 42.
The laminated panel P1 and the like can be standardized, and can constitute a main part of one vehicle body. Further, the length of the welding line can be shortened and the cost can be reduced.

The above-described vehicles are examples of the main ones, and there are various combinations such as combining the private room 90 and the guest room for the honor vehicle into one vehicle.

In one train, after the vehicle is manufactured,
After several years, changes in the balance of passengers between ordinary cars and honor cars, changes in the need for service facilities such as private rooms and cafeterias, changes in the purpose of using the trains (from express trains to stops at each station), etc. Occurs. In this case, since the window pitch of the train set is the same, it can be easily coped with by changing the interior equipment.

The embodiment shown in FIG. 16 will be described. Here, the laminated panel between the entrance units 45A and 45B will be mainly described. In this embodiment, the laminated panel of the side portion 40 includes a portion below the window 42 (second laminated panel) , a portion above the window 42 (first laminated panel) , a window 42 and a window 42.
