SIDE SILL FOR LOW LEVEL FLAT RAIL CAR

摘要

A side sill includes an inner upper leg having a leading edge adapted t o be attached to the deck plate of a flat rail car. The inner upper leg extend s from the flat rail car to a generally horizontal connecting leg extending from the inner upper leg to an outer leg. An upper portion of the outer leg extends from the connecting leg down to a portion where the outer leg can be connected by the deck plate by welding or the like. A lower portion of the outer leg extends from the deck plate to a generally horizontal connecting leg which provides attachment for cross brace members, bolster assembly components and the like. The welding of the deck plate to the leading edge o f the inner upper leg and to the outer leg provides a tube configuration to the assemble d side sill greatly increasing the rigidity of the flat rail car.
