Abstract: Starting from a classification of "dead zones" in track circuit, this paper objectively analyzes the cause reasons of "dead zone" and the harmfulness in track circuit application, and proposes the countermeasures, i.e., eliminating the "dead zones", shortening the "dead zones" and relocating the insulation joint at the scissors crossover. Considering the current situation of "dead zone" management, it also proposes such suggestions as source control through improved design, improvement of existing equipment and improvement of rules and regulations, which have strong operability and high reference significance.

Key words: track circuit, dead zone, scissors crossover
