Driving sustainable intercity connectivity through high-performance engineering
High-speed rail is a key enabler of sustainable development, offering fast, efficient and low-emission alternatives to air and road transport. At Sener, we bring more than 35 years of experience in high-speed rail engineering, having developed technical services for over 5,000 km of high-speed lines and feasibility studies for more than 8,000 km across Europe, the Americas and Asia. Our global presence, multidisciplinary teams and end-to-end approach make us a reliable partner for designing, managing and integrating large-scale rail infrastructure.
Our engineering footprint spans some of the world’s most iconic high-speed projects, including HS2 (London–Birmingham), the California High-Speed Rail (San Francisco–Los Angeles) and major nodes in Spain, Poland, France, Portugal, Norway, USA, UAE and UK. Our designs support not only line infrastructure, but also urban integration and multimodal terminals.
How we support the high-speed rail sector
We deliver integrated services for planning, design, construction and operation of high-speed rail systems and also depots and workshops.
We offer end-to-end services tailored to each client’s technical, economic and social context. Our engineering teams cover every discipline — from track design and viaducts to electrification, signaling and rolling stock specification. We also provide RAMS, ISA certification and system integration. As authors of multiple technical guides for the International Union of Railways (UIC), our expertise is trusted at a global level to define standards, not just follow them.
We authored UIC’s High-Speed Railway Implementation and Start-Up Handbooks, and our thought leadership has been recognized by international institutions. We are not only builders of high-speed infrastructure — we help define how it should be implemented and optimized through trusted, science-based frameworks.
Our experience spans iconic projects such as HS2 in the UK, the California High-Speed Rail, and national networks in Spain, Portugal, France, Poland, Norway, the USA and the UAE. By combining civil engineering, systems integration and certification expertise, we deliver corridors that connect regions efficiently, sustainably and at scale.
From strategic planning to construction oversight, we integrate design, digital modeling (BIM), technical studies and commissioning under a unified methodology. We work closely with public authorities, private developers, concessionaires and operators, ensuring that projects are aligned with strategic mobility goals and executed with the highest standards of quality and safety.
Our work spans track alignment, viaducts, tunnels, electrification, signaling, stations and terminals, complemented by RAMS methodologies, BIM integration and system simulation. We also support operators with rolling stock specification, operations consulting and certification services, ensuring that every corridor is safe, efficient and scalable.
We manage every stage of a high-speed rail system, including pre-feasibility, demand modeling, detailed engineering, risk analysis, operations support and certification. Our approach ensures consistency and cost-efficiency across the infrastructure and its supporting systems.
