A full side openable boxcar is provided according to the present application, which includes multiple doors movable in a direction of a body of the boxcar, and opening and closing devices each being configured to activate the opening and closing of the respective doors; in a closing state, the doors are arranged sequentially to form one side wall of the full side openable boxcar, and opening is required, the opening and closing devices activate the doors to translate in an inner-outer direction, to allow the doors to he staggered and moved in a longitudinal direction of the car body to open the corresponding position of the full side openable boxcar. The design of a door assembly is optimized so as to improve the simplicity and flexibility of door opening and closing, thereby ensuring the improvement in cargo loading and unloading efficiency.

Provided is a railway vehicle capable of constructing a highly reliable seal for a side hinged door with a small number of manufacturing steps. The railway vehicle includes: a side structure 20; an opening portion 10 provided in the side structure 20; a side hinged door 12 configured to close the opening portion 10; a door pillar 22 provided on a vehicle interior side of a peripheral edge portion of the opening portion 10; a retainer 24 provided on the door pillar 22; and an expandable seal rubber 25 gripped by the retainer 24 and expanded by pumped air. The retainer 24 includes a seal damming portion 24a that protrudes toward the opening portion 10.

A door assembly for a railcar includes a sliding system and a latching system. The sliding system is operable to slide the door to a side of the entrance of the railcar to provide an opening path to an entrance of the railcar. The sliding system comprises one or more rollers used for sliding the door. The latching system is operable to plug the door to the railcar such that the door moves inward toward the railcar, and unplug the door from the railcar such that the door moves outward from the railcar. The latching system comprises a lever operably coupled with two or more gears. The lever turns a particular number of rotations in a first direction to plug the door to the railcar. The lever turns the particular number of rotations in a second direction to unplug the door from the railcar.

A vehicle lock which eliminates the need for lubrication and which includes a bracket, a first base attached to the bracket, a second base attached to the bracket, aligned first and second apertures in the first and second bases for slidably receiving a. locking pin, a replaceable first locking pin wear protector lockably insertable in and selectively removable from the first base to prevent contact between the locking pin and the inner edge of the first base which defines the first aperture, and a replaceable second locking pin wear protector lockably insertable in and selectively removable from the second base to prevent contact between the locking pin and the inner edge of the second base which defines the second aperture.

The invention relates to a double-leaf vehicle door device comprising at least the following: two door leaves, each of which can be moved between an open position and a closed position in the form of a respective end position and into any intermediate position between the first open position and the first closed position, wherein a first movement of the first door leaf between the first open position and the first closed position is carried out without mechanically coupling the first door leaf to the second door leaf in contrast to a second movement of the second door leaf between the second open position and the second closed position, and a common locking device is provided which locks the first door leaf in the closed position when the first door leaf is located in the closed position and which locks the second door leaf in the closed position when the second door leaf is in the closed position. A pre-locking function is provided such that of the first door and the second door leaf, the door leaf which first reaches the closed position is held in the closed position at least until the other door leaf has also reached the closed position, and the locking device is additionally designed to only then lock or become capable of locking the first door leaf and the second door leaf.

An assembly-type car body and a rail vehicle. A roof, an underframe, side roofs and side walls of the assembly-type car body are separately formed by assembling double-layer pultruded profiles, and each double-layer pultruded profile comprises an outer plate, an inner plate and cavities formed by separating an interlayer between the outer plate and the inner plate using ribs; the upper edge and the lower edge of each side roof are respectively connected to an edge of the roof and the upper edge of a side wall by means of lapping joints, and the lower edge of each side wall is connected to an edge of the underframe by means of a side wall connector; each side wall connector is a double-layer pultruded profile unit, the upper edge of the side wall connector is connected to the lower edge of the side wall by a plug joint.
