Abstract: The paper is a brief summary of White Paper: Digital Transformation for China Railway Communication and Signaling Engineering, recently released by China Railway Society. The current situation of communication and signaling engineering is analyzed, and the full-lifecycle digital ecosystem of such engineering is put forward. This paper analyzes the digital transformation proposal from four aspects such as design, construction, the collaboration between construction and maintenance, as well as BIM technology application, and gives suggestions regarding the development and management of communication and signaling engineering based on digital twin engineering.

Key words: digital ecosystem, communication and signaling engineering, full lifecycle
