A door system has a door leaf configured to be moved between closed and opened positions while carrying out a door leaf movement. The door leaf is moved in the vehicle transverse direction across a door leaf movement distance in the vehicle transverse direction, a door seal, disposed underneath a lower edge of the door leaf closing off the door leaf towards the bottom, and extends along the lower edge. The door seal is arranged such that the door seal, when the door leaf movement is carried out, undergoes a door seal movement and is moved in the process in the vehicle transverse direction across a door seal movement distance in the vehicle transverse direction. An arrangement of the door leaf and door seal that ensures that the door seal movement distance in the vehicle transverse direction is smaller than the door leaf movement distance in the vehicle transverse direction.

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.

A bifold door includes a first hinge and a second hinge configured to rotatably couple the bifold door to a doorframe. The bifold door includes a slider configured to slide within a track of the doorframe as the bifold door is opened and closed. At least one of the first hinge, the second hinge, and the slider includes a spherical bearing and a pin.

Disclosed is a hopper car gate assembly including a frame configured for attachment to a hopper car body. The frame defines an opening and includes a beam, wherein the beam has a slot formed therein. A stop plate is removably attached to the beam to selectively obstruct the slot. The assembly has a door supported by the frame. A stop block is attached to the door, wherein the stop block is located on the door such that when the door is inserted into the frame the stop block is aligned with the slot. With the stop plate attached to the beam, the stop block engages with the stop plate to define an open position and prevent further movement of the door in the open direction. With the stop plate detached from the beam, the stop block passes through the slot to allow removal of the door from the frame.

The present application relates to an opening and closing mechanism and a train having the same. The opening and closing mechanism comprise a driving device, a locking device and a support arm; the driving device is connected to the locking device to drive the locking device to rotate; a first end of the locking device is rotatably mounted on a baseplate; a sliding groove in which a second end of the locking device is slidably located is formed on the support arm; a first end of the support arm is rotatably mounted on the baseplate; a second end of the support arm is connected to a fairing; the driving device drives the locking device to rotate, the locking device drives the support arm to rotate by the sliding groove, so that the support arm opens or closes the fairing.

A pinch detection sensor, for detecting the occurrence of pinch during closing of a sliding door, includes a door front edge rubber including a hollow portion inside, to be attached to a front edge portion of the sliding door in a closing movement direction of the sliding door, and a plurality of linear shape pressure sensing members accommodated in the hollow portion, each linear shape pressure sensing member comprising a tubular elastic body and respective conductor wires spaced apart from each other in an inner side of the tubular elastic body. The door front edge rubber includes, in the hollow portion, a plurality of housing spaces, which accommodate the plurality of linear shape pressure sensing members, respectively. Movements of the linear shape pressure sensing members between the plurality of housing spaces are restricted by a partitioning portion.

A centering apparatus for bi-directionally pivotable hopper doors. The apparatus is coupled between a frame of a hopper car and a bell crank of a hopper door. The apparatus includes a housing with a piston extending from one end. An end of the piston within the housing includes a piston head. A pair of coil springs are disposed within the housing on opposite sides of the piston head and counteract one another to bias the piston head toward the center of the housing and thus bias the hopper door toward a closed state. In a second configuration the apparatus includes a double-acting actuator with a pair of independent piston assemblies. An actuation system coupled to the actuator maintains the actuator and an associated hopper door in a closed position in a normal state and returns the hopper door to the closed position upon a failure in the system.

A method for operating a boarding system for a vehicle includes reading in an inclination signal. The inclination signal represents an inclination of the boarding system relative to a reference. The method also includes reading in at least one movement process of at least one boarding element of the boarding system representing process signals and includes determining an operating signal for operating the boarding system using the inclination signal and the at least one process signal.

A control and drive assembly for a transport vehicle door, and which includes a main control unit; a main motor to drive the door leaves and which is controlled by the main control unit to displace the leaves; an auxiliary control module; an auxiliary motor operable to: control the auxiliary motor so as to displace the leaves in at least one direction to a closed position, control a locking of the leaves in the closed position; and a connection device arranged between the main control unit and the auxiliary motor to facilitate transmission of a reference signal by the main control unit to the auxiliary control module, the reference signal being representative of a proper operating state of the main motor and the main control unit. The auxiliary control module is operable to actuate the auxiliary motor when the auxiliary control module does not receive the reference signal.

A deployable measurement system for analyzing a rail of a railroad track includes a housing, a reflecting assembly coupled to the housing, a movement assembly coupled to the housing, and an optical measurement system disposed within the housing. Both the housing and the reflecting assembly are moveable between a stored position and a deployed position. The movement assembly includes a deployment assembly that moves the reflecting assembly from the stored position to the deployed position, and a retraction assembly that moves the reflecting assembly from the deployed position to the stored position. The optical measurement system emits and receives light. The reflecting assembly reflects the emitted light toward the rail. The reflecting assembly reflects light reflected off of the rail toward the optical measurement system. The light received by the optical measurement system is used to measure parameters related to the rail.
