Guiyang completes signal system connection between metro lines 2, 3

Guiyang Urban Rail Transit Operation Co, together with China Railway Wuhan Electrification Engineering Group Co, recently finished building the interconnecting signal system for Guiyang Metro Lines 2 and 3 in Guiyang, capital of Southwest China's Guizhou province. 

The project aimed to establish a signal system interface at the junction of Line 2 and Line 3, providing system protection for train switching and ensuring the safety of such operations. 

With the successful interconnection of these signal systems, Guiyang Urban Rail Transit Operation Co will collaborate with the Line 3 operator and related manufacturers to carry out debugging work for the signal system interlocking function on the connecting line between Line 2 and Line 3, to ensure the safety, stability, and reliability of the signal system.
