Abstract: ZPW-2000A track circuit system of passenger dedicated line is widely used in high-speed railways, and is one of the core basic signalling equipment. The whole transmission channel laid on site is long, and is divided into indoor signalling equipment and outdoor trackside equipment. There are many different kinds of equipment; especially the parameters of outdoor cable lines and rail lines are greatly affected by the surrounding environment, so it is difficult to be familiar with the whole track circuit system in a short time. In view of the current situation that there is no ZPW-2000A track circuit training system close to the actual field application, this paper puts forward a set of practical training processes and methods with strong implementation, which provides a reference for the field front-line maintenance units to further familiarize themselves with the track circuit system and improve the on-site emergency handling capacity.

Key words: ZPW-2000A track circuit, training system, emergency handling
