ABSTRACT:
A rail car includes substantially flat plate extensions interposed between upper and lower sections of the shell of the car to increase the internal volume of the car. The extensions are supported by lateral supports which extend laterally in the interior of the car and by longitudinal support beams also in the car interior which extend longitudinally of the extensions, are intersected by the lateral supports, and substantially prevent internal pressure in the car from being applied to the extensions.
