Abstract: This paper introduces the principle of ZPW-2000A frequency-shift modulated and impulse track circuit system and the technical advantages of this new track circuit system from three aspects: solving bad shunting, monitoring insulation damage and preventing insulation from scorching. By gaining practical experience from the track circuit design of the depot of Lanzhou West Station, this paper studies the differences between the new track circuit system and ZPW-2000A track circuit system, which can provide reference for relevant railway project designs.

Key words: ZPW-2000A, frequency-shift and impulse signal, track circuit, bad shunting, insulation damage, insulation burning
