Is it easy for Chengdu subway track maintenance personnel?

It is not easy. The subway runs for a long time, all during the day, and it stops at eleven o'clock in the evening, and maintenance can only be carried out after it stops. Subway maintenance personnel work hard, often late at night, and have great responsibilities, so it is not easy for Chengdu subway track maintenance personnel. As one of the important tasks of urban rail transit, the professional ability of subway track maintenance personnel is directly related to the safety of trains. The subway track maintainer assists in planning the work of the rail transit department and manages the decoration design and construction of various projects as a whole.
