The Midland Main Line electrification project (MMLE) by SPL Powerlines tackles the challenge of increasing rail capacity and sustainability across the UK’s Midland corridor. Faced with complex multidiscipline coordination, SPL adopted cutting-edge digital solutions, including a digital twin made with Bentley applications. This unified digital approach provided all project teams with real-time access to synchronized data via a secure, common platform, enhancing safety and reducing costs. Automated quality assurance, UAV surveys, and efficient workflows yielded a 94% reduction in site visits and significant environmental savings, including carbon reduction equivalent to 500 airline flights between New York and Paris. By streamlining design and preventing on-site errors, these digital tools accelerated the project timeline, minimized waste, and ensured sustainability in line with U.K. decarbonization goals. The MMLE is now a model for sustainable, digital-first infrastructure development.
