Implementation of TSI requirements in railway infrastructure modernization projects of Ukraine in the context of EU transport system integration

Olena Bal Volodymyr Tverdomed Oresta Kovalchuk Liliia Solodiak Nataliia Borys

The article is devoted to the analysis of technical and institutional aspects of the implementation of the  requirements  of  the  Technical  Specifications  for  Interchangeability  (TSI)  in  projects  for  the modernization of the railway infrastructure of Ukraine with financial support from the European Union within the framework of the Connecting Europe Facility (CEF) program. The current regulatory and institutional framework is analyzed, barriers and risks are identified, and models of cooperation with European certification bodies are proposed. The main attention is paid to the project "Modernization of the  Mostyska-Lviv  railway  connection" as  a  representative  example  of  integration into  the  TEN-T network. The article substantiates the feasibility of implementing a pilot model of cooperation between Ukrainian institutions and European certification bodies to confirm the compliance of design solutions with  the  TSI  requirements.  Special  attention  is  paid  to  the  issues  of  ensuring  traffic  safety,  risk management,  environmental  safety,  and  compliance  with  functional  safety  standards,  which  are critically important for the certification of infrastructure facilities and obtaining funding from the EU. The pilot model of cooperation between Ukrainian participants and European certification bodies proposed in the article can become a scalable tool for ensuring TSI compliance. Institutional support from ERA and CINEA, technical dialogue, national capacity building and a multidisciplinary approach to project evaluation are the determining conditions for Ukraine's full participation in the European railway system
