A ceiling module for a vehicle has a pivotally mounted ceiling flap for covering a ceiling opening, and a carrier device for holding one or more electrical components. In order to save space in the vehicle, the carrier device includes a lateral wall with a hinge opening on which the ceiling flap is pivotally mounted.

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.

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.

Intermodal vehicles may be loaded with items and an aerial vehicle, and directed to travel to areas where demand for the items is known or anticipated. The intermodal vehicles may be coupled to locomotives, container ships, road tractors or other vehicles, and equipped with systems for loading one or more items onto the aerial vehicle, and for launching or retrieving the aerial vehicle while the intermodal vehicles are in motion. The areas where the demand is known or anticipated may be identified on any basis, including but not limited to past histories of purchases or deliveries to such areas, or events that are scheduled to occur in such areas. Additionally, intermodal vehicles may be loaded with replacement parts and/or inspection equipment, and configured to conduct repairs, servicing operations or inspections on aerial vehicles within the intermodal vehicles, while the intermodal vehicles are in motion.

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.

Cover assemblies for railroad cars are disclosed. In some embodiments, the cover assemblies include a cover pivotably movable between closed and open positions. The cover assemblies additionally include a lid stop assembly including a release handle positioned adjacent to a cover handle and a first locking element operatively connected to the release handle. The lid stop assembly additionally includes a second locking element attached to, or formed with, the housing. The first locking element moves between a locking position in which the first locking element engages the second locking element to secure the cover in the open position, and a releasing position in which the first locking element is spaced from the second locking element allowing the cover to be moved from the open position toward the closed position. The release handle allowing the user to move the first locking element between the locking and releasing positions.
