The special train itself is a normal ordinary train, but it carries special people and things. For example, national leaders take special trains, special trains loaded with rescue and relief materials, special trains loaded with epidemic prevention first aid materials, special trains loaded with military materials such as rockets and weapons, and special trains temporarily organized in case of major emergencies.
The first train is the focus of the special train, and other trains must make way for the special train in time. Therefore, the railway system must make overall arrangements for the train diagram, create conditions for the special train to run, and ensure the safe, stable and punctual arrival of the special train.
