A railway car having a lowered center of gravity is provided. The underframe of the railway car is preferably formed by extending a series of cross bearers between a pair of side sills and spacing them laterally between a pair of end sills. A center sill is then preferably disposed on top of the cross bearers and extended between the end sills along a center line of the railway car underframe. One or more floor stringers are preferably also included and disposed generally parallel to the center sill and extended between the end sills. In one embodiment, the one or more floor stringers may be disposed on stringer support spacer beams positioned on one or more of the cross bearers.
