The Railway Industry Association's (RIA) report, 'Delivering a lower cost, higher performing net zero railway by 2050', addresses the need for a strategic approach to decarbonize the UK's rail industry while ensuring economic sustainability and improved performance. The report advocates for the deployment of battery electric multiple units (BEMUs), electrification of intensively used routes, and discontinuous electrification or fast chargers for less intensively-used routes to achieve significant carbon reduction by 2050. RIA's strategy emphasizes the importance of a unified industry approach to inform government policies and support the railway supply chain. The report also highlights the economic benefits of eliminating 'boom and bust' procurement practices and emphasizes the necessity of consistent delivery of electrification projects to reduce costs and ensure efficiency. While considering hydrogen trains as a potential solution for specific routes, the report favors BEMUs for their technological maturity and proposes the establishment of fast charging stations for optimal operations. RIA's thorough methodology, including independent assessments of potential passenger growth, provides a foundation for future planning and development in the UK's rail industry.
