Abstract: A gangway bellow includes an outer bellow presenting corrugations forming a plurality of valleys presenting each a valley top portion facing upwardly and connected at each end to a valley top corner forming a junction between the valley top portion and a respective bellow side. The gangway bellow further includes at least one drainage channel so that liquid accumulating into at least one of the valley top portions flows through the at least one drainage channel along the respective bellow side.

Abstract: A levitated train is propelled by a system including at least a pair of wheels in cotact with a rail head. The rail head has a horizontal top surface and two vertical sides on either side of the horizontal top surface. A wheel of each wheel assembly has a cylindrical side face with flanges at the top and bottom. The cylindrical face of each of the wheels is in contact with the sides of the rail. The wheel assembly is power driven by a corresponding motor to impart motion to the train. The train is provided with a plurality of such wheel assemblies to be propelled along a rail track. The width of the wheels is greater than the width of the rail head. The flanges on the side of the wheels in a wheel assembly limit the freedom of motion of the train during the levitation.
