It's good. Southwest Jiaotong University has a national laboratory in this field. A national laboratory is equivalent to at least five national key laboratories, with only 19 in China, representing the highest level in all industries. The National Laboratory of Modern Rail Transit is built on the basis of the existing State Key Laboratory of Traction Power (Southwest Jiaotong University) and is one of the second batch of 10 national laboratories designated by the state in 2006. It is the only national laboratory in universities in western China and the only national laboratory in the field of rail transit in China.
