Storage Assembly for Railcar
An IBC storage box assembly is elevated from a railcar. A vertical beam is used to elevate the storage box off the railcar so that the storage box is more easily accessed from a rail platform. Additionally, the vertical beam may provide some clearance for the storage box so that the storage box is not impacted by the railcar coupler during transport.
Railcar hatch cover
According to some embodiments, a hatch cover for an opening in a container comprises a body comprising a plate member for covering the opening in the container, a seal on the underside of the body for sealing the body to the container, and one or more pressure sensors disposed between the seal and the body. The one or more pressure sensors are operable to detect a pressure between the body and the container and are communicably coupled to a hatch status device operable to detect a change in pressure between the body and the container. Some embodiments may include a fill level sensor.
Manway relief for a tank car
A cryogenic tank car tank includes an outer tank, an inner tank positioned within the outer tank, an inner nozzle, and inner manway plate, an outer nozzle, and an outer manway plate. The inner nozzle defines an opening in the inner tank. The inner manway plate is welded to the inner nozzle and covers the opening in the inner tank. The outer nozzle defines an opening in the outer tank and is positioned above the inner nozzle, such that the inner manway plate is accessible through the outer nozzle. The outer manway plate couples to an upper edge of the outer nozzle to cover the opening in the outer tank. In response to applying the vacuum to the annular space between the inner and outer tanks, a differential pressure between the annular space and a space external to the outer tank secures the outer manway plate to the outer nozzle.

Safety railcar
A suppression system for use in a safety railcar may include a source of pressurized water connected to at least one foam tank containing a suppression foam. A controllable valve mediates flow of pressurized water from the source of pressurized water to the at least one foam tank. The controllable valve is controllable to permit flow of pressurized water to the at least one foam tank in response to detection of a hazardous event. A spray nozzle is connected to the foam tank via a rupture disc that is configured to rupture and permit flow of suppression foam from the spray nozzle when pressure within the foam tank exceeds a predetermined threshold.

COVERED HOPPER CAR WITH STIFFENED BULKHEADS
A covered hopper car including a plurality of hoppers adjacent one another along the length of the car, with a generally vertical stiffened bulkhead of sheet material between adjacent ones of the hoppers. The bulkhead may include a plurality of stiffeners of which each stiffener is a transversely oriented curved portion of the sheet material of the bulkhead itself, displaced from the vertical main plane of the bulkhead. A radius of curvature is great enough and all surfaces of the stiffener are steep enough that granular material will slide downward from the stiffener and all surfaces of the stiffener can easily be washed by a spray directed from a hatch opening in the roof of the covered hopper car.

Internal nozzle for a tank car
A cryogenic railway tank car includes an outer tank, an inner tank positioned within the outer tank, an internal nozzle, and a pipe. The inner tank includes a shell that defines an opening. The internal nozzle is coupled to the inner tank at least along a perimeter of the opening and extends in a radial direction through the opening and into the inner tank. A space defined by an interior surface of the outer tank, an exterior surface of the inner tank, and an interior surface of the nozzle is configured to hold a vacuum. The pipe is configured to transport the fluid between an exterior of the outer tank and the interior of the inner tank. At least a portion of the pipe extends from the outer tank to the inner tank through at least a portion of the nozzle.
