A pipe clamp wedge is disclosed that can be used with an existing pipe clamp anchor to secure a brake line pipe to a rail car. The wedge has a cradle portion having a concave side receiving the pipe, and a convex wedge side opposite the concave side. The cradle portion has a height increasing in a longitudinal direction, and a pair of opposed channels on lateral sides of the wedge are adapted to receive tabs on the pipe anchor. A pair of tabs on the wedge extends in the opposite direction from the tabs on the pipe anchor on either side of the cradle portion. Thus, the wedge can be slid onto the anchor, tightening around the pipe as the wedge moves in the longitudinal direction onto the anchor, and the wedge is dimensioned so that when the wedge cannot move further, the tabs on the wedge extend beyond the pipe anchor and may be bent up (toward the railcar) to secure the wedge. The parts of the combination are adapted so that sliding the pipe onto the anchor and bending the tabs may be done with a hammer.

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.

An aircraft including: a penetration member that penetrates an airframe between an inside and an outside via an opening provided in the airframe; a seal that seals a gap set between an opening formation member forming the opening and the penetration member; and a retainer that presses the seal against the penetration member and the opening formation member, wherein each of the penetration member and the opening formation member includes a receiving section that receives the seal, both of the receiving sections are arranged along a direction connecting one side and the other side of the gap with the gap therebetween, and the seal is fixed to only one of the receiving section of the penetration member and the receiving section of the opening formation member.

A foldable handhold assembly for attachment to a railroad flatcar includes a handhold that has a pair of side rails connected with a horizontal grab bar. A pair of brackets, which each have a mounting surface conforming to the shape of the flatcar sill. The brackets each have a hinge that rotatably couples to the proximate end of one of the side rail, which enables the handhold to rotate about the hinges between a deployed position where the grab bar extends above the flatcar deck and a stowed position where the handhold extends below the flatcar deck. One of the brackets also has latch aligned to selectively retain the handhold at the deployed position.

A screen turning-over mechanism includes a rotating shaft connected to a screen and a motor drivably connected to the rotating shaft. The motor is connected to an electromagnetic damping loop which forms a closed path with the motor only when the motor is in a de-energized state. The rotating shaft is also connected to an elastic mechanism. When the motor is energized, the motor drives the rotating shaft to rotate to extend the screen, and the rotating shaft drives the elastic mechanism to deform elastically to store energy; and when the motor is de-energized, the elastic mechanism releases the stored energy to drive the rotating shaft to rotate to retract the screen. The screen turning-over mechanism according to the present application has a simple and compact structure, occupies a small volume of space, and has a long service life.

According to some embodiments, a railcar comprises a railcar door for accessing an interior of the railcar, and a storage box comprising an access opening. The storage box is disposed such that when the railcar door is in a closed position, the railcar door prevents access to the storage box access opening, and when the railcar door is in an open position, the storage box access opening is accessible. In some embodiments the railcar door comprises a double door, and the storage box comprises a first portion coupled to a first door and a second portion coupled to a second door and adjacent to the first portion of the storage box. The first portion of the storage box prevents access to the second portion when the double doors are in a closed position. In some embodiments, the storage box is recessed into the railcar floor beneath the railcar door.

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.
