HS1 Limited, operating under the concession name London St Pancras Highspeed since 2025, is the infrastructure manager and operator of High Speed 1 (HS1), the UK’s pioneering high-speed rail line connecting London’s St Pancras International station with the Channel Tunnel and onward international destinations like Paris and Brussels. The company holds a 30-year concession granted by the UK government until 2040 to maintain, operate, and renew the HS1 rail infrastructure including key international stations such as St Pancras, Stratford, Ebbsfleet, and Ashford.
HS1 was completed in two major phases—Section 1 completed in 2003, and Section 2 in 2007. The rail line is compliant with UIC GC structure gauge and European Technical Specifications for Interoperability, utilizing advanced signalling (TVM 430) and powered by overhead electrification enabling trains at speeds up to 300km/h. HS1 Limited’s main mission is to facilitate fast, seamless, and sustainable rail travel between the UK and mainland Europe, with an emphasis on enhancing customer experience, operational efficiency, and environmental benefits.
Ownership lies with pension funds Borealis Infrastructure, OMERS, and the Ontario Teachers’ Pension Plan, reflecting stable long-term investment backing. The concession includes strict asset stewardship obligations overseen by the UK’s Office of Rail and Road (ORR) that governs track access charges and compliance with rail regulations. HS1 Limited collaborates closely with train operators like Eurostar International Limited, Network Rail (High Speed), and other stakeholders to ensure smooth operation and future-proof asset management.
Since its incorporation in 2007, HS1 Limited has rebranded to emphasize a consumer-facing, growth-oriented strategy to increase rail travel modality over other transport types in line with European sustainable transport goals. While primarily a rail infrastructure operator, HS1 Limited also engages in lobbying activities within the EU framework to influence regulatory policies vital to international rail infrastructure, cross-border transport, and related environmental and commercial legislation
