ABSTRACT:
A vehicle such as a railroad car is constructed by connecting together side and roof blocks, each equipped with interior components, in a manner to improve the outer appearance of the connections between the side and roof blocks. Longitudinal beams of the side blocks are in contact with the under surfaces of gutters formed by the outer plate of the roof block. The side and roof blocks, equipped with the interior components, are connected together at the gutter portions by a welding which can be conducted solely outside the vehicle. Inside the vehicle, the longitudinal beams and joints secured to the side blocks are connected to lateral beams of the roof block by rivets. Thereafter, a third interior plate is provided between interior plates of the side and roof blocks. Since the connections are formed at the gutter portions, the connecting operations can easily be conducted outside the vehicle and in a manner to assure a good outer appearance.
