[CRL_3] KF1 steam locomotive

In order to complete the railway from Chenzhou to Shaoguan, the Nanjing National Government borrowed money from the United Kingdom, and the United Kingdom also obtained the priority to provide the necessary railway vehicles. This section of the railway requires a locomotive with high power and low axle load, but there is no such locomotive in the UK. So the Nanjing government asked the engineer Ying Shangcai to start the design work.Because China did not have the ability to manufacture such locomotives, after a bidding process, the Vulcan Fondry in the UK won the bid for manufacturing. This is the first steam locomotive designed independently by the Chinese and the only locomotive with 4-8-4 axles after the founding of the People's Republic of China.There are currently two KF1 steam locomotives in existence, one in Beijing and one in York, England.

Known issues:
1. The pictures used for reference when making the module were taken by other people in the museum in Beijing. There were some parts that could not be identified, so I had to omit it first.
2. There are errors in the process of calculating the data in the geometric method when making animation, so there are abnormal vibrations in some parts.
3. The texture is still handled badly.
4. The bogie of a coal water waggon should have three axles, but the model seems to have a size problem. If a three-axle bogie is used, the distance between the bogies is too tight. In the early days, a two-axle bogie was used instead (I kept the total length at the correct size. The locomotive seems to be made a bit longer, making the coal water waggon shorter.)

annual summary:
This year I have produced and released a total of 34 freight cars, 3 locomotives, and 1 EMU. There is also a freight car that has not been released after completion.
The production level of freight carriage modules is showing a gradual improvement and getting better and better. However, the production of locomotives and EMU modules is still immature.
In summary, it should be caused by my overall thinking when making the model. I have received an education in mechanical engineering, so for a carriage, what I observe is not a shape, but a number of institutions that meet different functions. My modeling is also carried out according to this idea. Therefore, once it is impossible to understand what kind of function is realized by a set of mechanism that realizes a certain function, module production will fall into a dilemma. When I couldn't explain the functions and principles realized by the mechanism, I had to choose to omit the entire mechanism.
This idea can make freight cars very good, such as boxcars. Others will regard boxcars as internal and external shapes, while I see boxcars as floors, walls, and roofs. So the car I made naturally has an internal structure. This idea is also good when used on locomotives, but it will result in too delicate parts and rough overall. This can be improved, but I don’t know how to use this idea to make EMUs. The EMU I prototyped was made in accordance with the external and internal shapes. This is an idea I am completely unfamiliar with. Therefore, I have difficulty dealing with the problems encountered when making this car, which makes it a bloated work at present.
I believe my level will be better next year.
