A railroad car includes a body having a pair of side walls and at least a pair of parallel horizontal support beams extending along the side walls at substantially the same height. A movable end portion of a deck built as a lightweight composite structure may pivot with respect to the pair of support beams. A respective counterbalance apparatus is arranged between each of the pair of side walls and the movable deck portion at a location spaced apart from the pivot axis so as to provide a lifting force acting on the movable end portion to urge it to pivot upward about the pivot axis.
