Abstract:  Loss of occupancy is a very serious technical problem in the application of ZPW-2000A track circuit, which will lead to the upgrade of railway signals and seriously affect the safety of driving. This paper analyzes and discusses four causes of the problem of ZPW-2000A track circuit occupancy loss, including improper adjustment, bad shunting, detour loop and signal interference on the basis of actual cases.

Key words: track circuit, loss of occupancy, bad shunting, analysis and discussion
