Application Analysis of CTCS-3 in City Railway

Abstract

Objective At present, there is still no practical case of using CTCS 3 (Chinese Train Control System Level 3) in city railway in China. The application of CTCS-3 system in city railway should be explored to expand its application in urban railway. Method The characteristics of the existing city railway and the current status of CTCS application in city railway are analyzed. The technical scheme of CTCS-3 application in city railway is proposed, its applicability is analyzed, and the optimization proposal for its application scheme is put forward. Result & Conclusion Compared with the CTCS-2, the CTCS-3 (without CTCS-2 as backup) has better applicability in city railway in terms of its advantages in traction power supply system adaptability, protection section setting method, interconnection with other rail transit systems, and lower signalling engineering cost.
