Abstract: In the modern urban rail transit signal system, the axle counting system is equipped with
high degree of intellectualization and perfect system functions, which is gradually replacing track
circuits to detect the train occupation. This paper analyzes effects of axle count failure of the signal
system for Chengdu metro line 4, and discusses the emergency disposal of axle count failure during
operation of trains.
Keywords: axle count; working principle; emergency disposal; case analysis
