High-Speed Rail & Intercity Fast Rail

High-speed rail is passenger rail designed to operate at significantly higher speeds than conventional rail — greater than 155 miles per hour — typically connecting major cities with frequent, reliable service. It uses dedicated infrastructure, advanced signaling and purpose-built trains to reduce travel times, increase capacity and improve system performance.

A broader concept than high-speed rail, intercity fast rail also includes upgrading conventional railways to cater for faster and more frequent trains, providing an improved service and shorter journey times at a lower cost than dedicated lines. 

High-speed rail and intercity fast rail programs face challenges including complex approvals, engineering challenges, funding uncertainty, cost escalation, schedule delays and multi-stakeholder coordination. Without integrated planning and strong governance, these challenges can impact public confidence and long-term performance.  

High‑speed rail and intercity fast rail deliver faster, more reliable intercity travel — opening labor markets, boosting productivity and unlocking economic growth. By adding capacity on protected alignments and integrating with airports, metro and conventional rail, it strengthens a resilient, multimodal network. Attracting passengers who might otherwise have driven or taken ‑short haul flights cuts congestion and emissions while catalyzing ‑transit-oriented development, benefiting cities through new homes and communities.

Jacobs defines our high‑speed rail solutions through integrated digital delivery, flexible design and a strong focus on decarbonization—enabling faster, safer and more sustainable rail networks at scale. 

Jacobs builds climate resilience into every stage of delivery through data‑driven planning, resilient materials and systems, and designs that address extreme weather, sea‑level rise and long‑term operational performance. 

Our approach enables seamless integration into existing cities through compact station design, strong multimodal connections and phased delivery that minimizes disruption while maximizing community, economic and mobility benefits.
