China Railway Wagon for Mineral–K18Series

China Railway Wagon for Mineral–K18Series

Write in front
First, thank you to @彬伐 for providing reference materials for this series of carriages.
This is my first time modeling and making, so there may be some imperfections. When conducting detailed research on real cars, we only referred to information from one place. These cars will actually have some components customized according to user needs, such as reducing some transmission devices and braking equipment. Therefore, usually these cars are almost It also has local characteristics. I chose to make these places that did not match the drawings based on my own real shots, so this is a deviation.

Introduction
In 1967, my country developed a 60t coal hopper car that could improve the efficiency of railway coal transportation. After more than three years of application testing, summary, and improved design, it was officially designated as the K18 coal hopper car in 1971. In 1979, based on the K18 coal hopper car, the hopper, bottom door, and bottom door opening and closing mechanism were optimized and improved, and the K18F coal hopper car was developed. In 1980, based on the K18F coal hopper car, the bottom door opening and closing mechanism was improved from a double-armed knife-type eccentric locking mechanism to a top-locking opening and closing mechanism. The car body structure was partially modified accordingly, and the braking device was the K18D coal hopper car. Later, based on the K18D coal hopper car, the car body and wind control piping device were optimized and improved, and the K18DG series coal hopper car was developed. In 1999, based on the K18D coal hopper car, the independent wind control pipeline was optimized to take the wind source from the train supervisor, and the bottom door opening and closing device was optimized and improved. The K18DA coal hopper car was developed. In 2002, in order to adapt to the development requirements of my country’s railway freight cars to speed up, based on the K18DA coal hopper car, the K18AT equipped with an 8G bogie, and the K18AK coal hopper car equipped with a K2 bogie were developed. In 2004, based on the K18D coal hopper car, the K18DK coal hopper car equipped with a K2 bogie was developed.
The prototypes of the six cars produced this time, K18AK/BK/DK, are from real cars shot in Handan, Hebei. All pictures of K18, K18F, and K18GI are from the Internet. In addition to the current common black paint, these six cars also have factory red paint versions. The following is the preview made

Due to limited space, each car will not be displayed individually, please explore by yourself.
In addition, this time, like the previous one, the height is adapted to different cargo capacities.
