Is it difficult for mechanical undergraduate to design and manufacture automatic railway administration?

Difficult. Even if the major of unified recruitment is mechanical design, manufacturing and automation, the railway department is directly recruited through schools, not professional railway schools. Because the major is not right, the railway department will not go to the school to recruit. Even if the railway department recruits for the society, most of them are labor dispatchers. Mechanical design, manufacturing and automation is an undergraduate major in colleges and universities in China, which belongs to the mechanical category. After studying for four years, I was awarded a bachelor's degree in engineering.
