A vessel for transporting a material that is solid or semi-solid at ambient temperature, includes a body having an interior surface comprising textured metal, and a superoleophobic coating on the interior surface for inhibiting the material from adhering to the interior surface, the superoleophobic coating including a nanotextured coating disposed on the textured metal and functionalized with a fluorinated compound. The superoleophobic coating facilitates flow of the material along the interior surface.

A manway cover assembly can be used to control access to the interior of a railroad tank car or other type of tank or structure. The manway cover assembly can have a tightening system, such as a screw tightening system and an attachment system. The attachment system can have a ledge configured to engage a flange that surrounds an opening. A cover can control access to the opening. The tightening system can secure the ledge to the flange and lock the cover over the opening. A manway cover assembly can also be used for selectively sealing an access passageway of a tank. The manway cover assembly can have an internal seal that remains sealed independent of movement between the cover and the opening within a set range of movement.

Disclosed is a railroad train or tank car for transporting oil and other combustible fluids with an outer fluid-filled shell designed to greatly reduce the potential for an explosion if a train car tank derails. The tank car has an outer shell that is surrounded by a flame-retardant fluid that eliminates sparks resulting from derailment that could cause the oil or other combustible fluid contained by the tank car to combust and burn. An additional feature of the invention is a train car coupler with springs on each side so the coupler can move freely. The movement allowed by the springs would prevent derailment that could occur when a train was going around a curve. This is especially beneficial when train cars are of different weights, such that a heavier car going around a curve that gets derailed could not derail a lighter or empty car that is connected.

A hatch cover for a covered hopper railcar includes a substantially circular shell member having a radially outer circumferential perimeter. The substantially circular shell member includes a topside surface and an underside surface. The hatch cover also includes a downwardly extending rim member coupled to and unitarily formed with the substantially circular shell member. The substantially circular shell member and the downwardly extending rim member define a shell/rim interface at the underside surface. The hatch cover further includes at least one sealing gasket fixedly coupled to the underside surface proximate the shell/rim interface.

A transportation device, such as a rail vehicle, has a water supply device with a freshwater tank, at least one used water device connected to the freshwater tank and a collecting container connected to the used water device. The collecting container collects and stores used water which comes from the used water device The water supply device includes a control device which, by way of at least one control signal, can predefine one of at least two different operating modes, specifically a normal operating mode and an economy operating mode in which, compared to the normal operating mode, at least one operational resource which is necessary to operate the water supply device is consumed to a lesser extent than in the normal operating mode.

According to some embodiments, a method of assembling a tank car comprises assembling a top platform. Assembling the top platform comprises coupling a first running board to a first handrail assembly such that it at least partially encloses the first running board; coupling a second running board to a second handrail assembly such that it at least partially encloses the second running board; and coupling the first handrail assembly to the second handrail assembly via at least one closure plate to form a passageway for a rail operator to pass between the first handrail assembly and the second handrail assembly. The method further comprises coupling the top platform to the tank. Particular embodiments include leveling the top platform on the top of the tank.

According to some embodiments, a tank car comprises a tank; a top platform coupled to a top of the tank comprising a walking surface; a walkway platform extending longitudinally between an end of the tank and the top platform comprising a walking surface disposed above a line tangent to the top of the tank; and a closure plate coupled to an end of the walkway platform proximate to the top platform. The closure plate extends below the walkway platform to cover access to a space between the walking surface of the walkway platform and the top of the tank. In particular embodiments, the top platform comprises a first and second handrail assembly and a space between the handrail assemblies for accessing the walkway platform. The closure plate covers access to the space between the handrail assemblies and below the walkway platform.
