Minimum Headway of EMU and Common Passenger Train of High-Speed Railways

The minimum headway of trains is an important technical standard in railway survey and design. Common passenger trains on high-speed railway have great influence on the headway of trains. This paper mainly analyzes the type of coach, passenger train composition, and train operation control system. The calculating model of headway of EMU and common passenger train was put forward in this paper. According to the calculating model, based on the train control system level 2 (CTCS-2) for China and the train running monitor and record device (LKJ) and the ground signals, taking the YunCheng northern station of Datong-Xi'an high-speed railway as example, the arrival-pass and arrival-arrival headway of common passenger trains and EMU and the pass-departure headway of EMU and common passenger train can realize 3 minutes. And the departure-departure headway of EMU and common passenger trains can realize 5 minutes. And some valuable research results will be provided for survey and design of special lines for passenger traffic.
