Abstract: A shipping container support mechanism for a rail freight wagon is adjustable between a retracted position in which a container can be supported in a well of the wagon between elevated end platforms which extend over wheels and bogies. In the deployed, extended position, the mechanism supports an end region of a container, the opposite end of which can be supported on another such mechanism or an end platform. The support mechanism is mountable in the side wall of the wagon and has a pivotal support arm which can move from a stowed position in the wagon frame to a horizontally extended position.

Abstract: A freight rail car suspension has independent but co-operating springs; a first spring is load carrying and has a variable damping function and a second control spring operates on a friction shoe to apply a constant damping component. A practical embodiment has a friction shoe engaged for vertical displacement by the first spring which is mounted on a side frame and the second spring is obliquely arranged between the bolster of the bogie and the friction shoe, which has guides to cause it to move into greater frictional engagement upon load being applied through the spring. This arrangement provides a dual damping characteristic involving both constant damping and variable damping forces.
