Integrated approach to implementing control-command and signalling, telecommunications, and power supply systems for High-Speed Rail in Poland

Abstract: In the introduction, the article discusses the specifics of CCS, telecommunications, and power supply systems on railway lines, as well as the barriers to effective implementation of these systems to date. It also characterizes the technical specifics of the planned Polish HSR network. The article then outlines the key role of the Eulynx specification in defining the requirements for CCS systems on this HSR network, presents the optimal hardware architecture for this system, and discusses the important role of telecommunications and data transmission systems and their designed technical characteristics. The next system described is the 2x25 kV AC traction power supply, where, in addition to the technical aspects, the succes story is presented regarding the design of this system and the arrangements for its connection to the power transmission grid in Poland. In conclusion, an implementation approach is presented, understood as the optimal split of tenders and contracts for industry packages.
