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.

The manual release mechanism described herein enables a passenger to attempt to manually open the transit door, but delays opening until the vehicle is no longer moving. A motion transfer device (14) moves to an unlocking position of the door lock (10) only when the manual release mechanism is activated to store energy in a mechanical energy storage device (40), and an electromechanical device (26) is de-energized to release the motion transfer device (14).

A double-track vehicle, comprising upper and lower carriages, which are respectively a passenger carriage (1) for providing passenger seats and a cargo carriage (2) for placing cargo, the passenger carriage (1) and the cargo carriage (2) being respectively provided with a passenger door (3) for passengers to get on and off and a cargo door (4) for loading and unloading cargo. The vehicle carries out simultaneous transport of passengers and cargo, allowing for the function of the rail vehicle to no longer be singular and largely reducing transport and maintenance costs. At the same time, passenger transport and cargo transport are divided into two layers, which completely separates cargo transport and passenger transport, thereby providing passengers with a comfortable seating environment and improving seating safety.

A fire suppression system includes at least one spray nozzle for expelling a fire suppression agent into a space; a first container at least partially filled with a first fire suppression agent. The first fire suppression agent within the first container has a first pressure. A conduit extends from the first container to at least one spray nozzle. A second container is at least partially filled with a second fire suppression agent and is arranged in fluid communication with the conduit. The second fire suppression agent within the second container has a second pressure less than the first pressure. A mixture of the first fire suppression agent and the second fire suppression agent is movable through the conduit to the at least one spray nozzle via the first pressure.

A movable side wall and opening/closing mechanism for railroad boxcars, comprising a side wall assembly (1), an end-portion opening/closing mechanism (2), a hinged rod assembly (3), a lateral door central clamping device (4), a upper transmission shaft assembly (5), a lower transmission shaft assembly (6), a upper track assembly (7) and a lower track assembly (8); upon loading/unloading cargo, the movable side wall can be opened further, so as to allow multiple forklifts of any tonnage on the ground to load/unload cargo to/from any positions of a carriage; the hinged rod assembly (3) and the central clamping device (4) are provided to keep the movable side wall reliably closed in order to ensure security and self-locking during transportation.

A multimodal platform is provided for a railcar. The multimodal platform includes a first underframe, a second underframe, a loading platform, and rail wheels. The first underframe carries a first container and the second underframe carries a second container. The second underframe is coupled to the first underframe and coupling the first underframe and the second underframe provides an articulation point. The loading platform is disposed above the articulation point and between a first end of the first container proximate the second container and a second end of the second container proximate the first container. The rail wheels are disposed under the loading platform and coupled to the first underframe and the second underframe. The rail wheels are configured to transport the multimodal platform on rails of a railway.
