Abstract: High-voltage pulse track circuit is one of the new track circuit systems to solve the problem of poor shunting of track circuits. After being applied in some stations, the poor shunting caused by rail surface corrosion has been improved, but in practical application, there is the problem of interference with locomotive signals. Based on the actual cases, this paper analyzes the causes and mechanism of the potential problem caused by the high-voltage pulse track circuits applied in the electrified sections, and puts forward some targeted improvements.
