The organization of project management of the modernization of railway transport infrastructure in conditions of digitalization is an important aspect of the development of the transport industry, which requires a deep analysis and understanding of modern trends. The article is devoted to the study of approaches to projects in the modernization of railway transport infrastructure aimed at the implementation of digital innovative technologies. The authors consider railway transport as a key element of urban mobility, which is experiencing a period of significant changes caused by modern trends towards digitalization and innovation. The research substantiates the current challenges facing the industry, including the need to increase efficiency, reduce costs and improve the quality of services. Emphasis is placed on the importance of implementing the latest IT solutions, such as IoT, AI, machine learning and 5G technologies, which can provide greater security, reliability and optimization of resource management. The article defines various aspects of the modernization of railway transport, which includes not only technical innovations, but also the development of an organizational and economic project management mechanism. The article develops an organizational and economic mechanism for managing infrastructure projects in railway transport. This mechanism includes a set of measures and structural relationships aimed at effective functioning and development of the project in the conditions of digital transformation. In particular, attention is focused on the need to implement information technologies for the automation of management processes, data analysis and strategic decision-making, as well as resource optimization and project effectiveness maximization. The authors suggested the use of modern project management methods, such as Agile and Scrum, and the introduction of innovative approaches to the management process based on Big Data analysis and the use of artificial intelligence. Strategies for risk management and ensuring a high level of information protection in terms of digital security have been developed, which plays a key role in the successful implementation of transport infrastructure projects
