The analysis of selected issues of signalling system selection for a railway line with set railway service and traffic parameters

One of the essential elements of the railway transport modernization in Poland is the implementation of modern systems of interoperable ERTMS / ETCS (European Rail Traffi c Management System / European Train Control System) fulfilling the tasks and functions of CCS (control-command and signalling) systems. Th e investment process including the implementation of ERTMS / ETCS requires prior development of a number of documents, which include feasibility study, terms of reference, a description of the contract and many others. Th e initiation of the investment process is preceded by a series of activities including the evaluation and selection of the right target railway traffic control system for the selected railway line. Due to the interoperability requirements, it becomes necessary to develop methods for assessment of the possible ERTMS / ETCS confi gurations and later selection of a confi guration for a railway line with predefi ned service and traffic parameters. The aim of the publication is to present a concept that can be considered as the basis for methods of analysis and rail control traffic system selection. The sample line, which was selected to carry out research and analysis, is a section of the selected railway line section of the railway line No. 7 due to its strategic location and traffic load.
