Abstract Research purposes: The current signaling system can not meet the increasing transportation demand of heavy haul railway, the paper proposes the development trend and key technology of signaling system of heavy haul railway after analyzing the technical achievements abstracted from domestic and abroad typical signaling system, which can be taken as reference for signaling equipment development and technical solution selection.
Research conclusions: (1) The signaling system technology in foreign countries has made a big breakthrough, i.e., ETCS-2+ATO train control system applied in AutoHaul project in Australia has achieved GoA4 class automatic driving of heavy-haul railway. (2) The future trends of signaling system for heavy haul railway include: trackside equipment shall be as less as possible and onboard equipment shall integrate multiple functions; moving block and ATO shall be applied; intelligent and efficient traffic dispatching and maintenance shall be achieved. (3) The research results can provide reference for signaling equipment development and technical solution selection.
