Abstract:

Sustainability has become a critical aspect of railway manufacturing engineering projects due to environmental concerns, regulatory requirements, and the need for long-term economic viability of large-scale infrastructure systems. Beyond strict regulations, innovative technologies, and stakeholder coordination, Germany is one of the examples of the progressive implementation of sustainability principles in the railroad industry. The paper provides a concept synthesis of the sustainable practices in the railway engineering project based on the literature in manufacturing engineering, railway systems, project management and sustainability research. The concept of sustainability is encompassed in the project lifecycle, design, material selection, production processes, digitalization, supply chain management, and governance structures. Among the areas of focus, lifecycle orientation can be mentioned, along with the use of green technologies, the adoption of digital technologies, and tools that facilitate sustainable decision-making, e.g., BIM, automation, and data-based systems. The articles highlight the significance of stakeholder engagement, alignment of regulations, and the sustainability of the supply chain to project success. There are also persistent challenges that are addressed, high initial costs, technical integration issues, organizational resistance and regulatory discrepancies. Experiences in Germany provide insight into how sustainability can be improved through regulatory compliance, digitalization, and collaboration. The research offers systematic insights for future research and practice that could be used to enhance environmental performance, functional effectiveness, and sustainability.
