Abstract：Abstract ： Research purposes ： This paper focuses on difficulties in Dandong - Dalian railway signal engineering design， including integrated grounding at subgrade sections outside stations， remote video monitoring of switch gaps， balises
setting at link stations to C3 sections and not - only - passenger stations，and dispatching design of Jinzhou station，
analyzes the feasibilities of various programs，and proposes the ultimate solution.
Research conclusions ：( 1 ) The directly buried mode linking up grounding wire at subgrade sections outside stations
could conform to requirements of ground resistance mostly. ( 2) Switch gap video monitoring system networking
independently could make the remote monitoring real - time. (3) Balises setting mode of C2 and C3 at link stations to
C3 sections should be compatible with each other. (4 ) Balises setting at not - only - passenger stations should satisfy requirements of transport. (5 ) Jinzhou station should have different centralized control mode of railway bureau or
station，depending on requirements of transport. (6) The research result can provide reference for other similar railway
project.
