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.

A tanker railroad car with one or more non-contact sensing assemblies that are configured to sense a level of fluid in a tanker railroad car using one or more non-contact sensors, wherein the non-contact sensing assemblies are configured to communicate with a converter device that translates output signals from the non-contact sensors into readings of the level of fluid in the tanker railroad car in desired output units.

An electrically conductive assembly for providing a low electrical resistance contact between an antenna and the corrugated roof of a train. The assembly comprises a gel and skeletal gasket member which has an electrically conductive skeleton encapsulated in a tacky gel. Multiple foam and gel members, typically made up of compressible at least partially open cell foam, are laid in the troughs and are thick enough, such that the top surface of the foam and gel members is about equal to or slightly higher than the top surfaces of the ridges of the corrugated train roof. The antenna is then laid atop the gel and gasket member and bolted to the roof with fasteners in such a manner that the tacky flowable gel at least partially squeezes out the edges of the gel and gasket member as the antenna is compressed downward while the fasteners are snugged up. This compression allows the electrically conductive skeletal member to provide contact between the antenna and the roof, the roof typically metallic and that results in a decrease of EMI (electromagnetic interference).
