The Next Chapter: High-Speed Rail in 2024 and Beyond

The global map of high-speed rail is changing fast. Dozens of new lines are under construction or in advanced planning across Europe, Asia, and beyond — while laboratory engineers are already testing the generation after next. Here is a comprehensive survey of where HSR is heading in the coming decades.

United Kingdom: HS2

Britain's High Speed 2 project is the most politically contentious HSR project in the world. Planned as a Y-shaped network connecting London Euston with Birmingham, then branching to Manchester and Leeds, HS2 has been scaled back significantly. In October 2023, Prime Minister Rishi Sunak announced the cancellation of the northern leg beyond Birmingham — a decision that left HS2 as a London–Birmingham commuter upgrade rather than the transformational national network originally envisioned.

Phase 1 (London–Birmingham, 230 km) remains under construction, with an estimated opening date of 2033–2035 and a total cost now estimated at £45–67 billion — more than double the original budget. Trains will operate at 360 km/h on dedicated track, reducing London–Birmingham journey time from 1h21 to approximately 49 minutes. The wider question of HSR for northern England has been redirected into a less ambitious "Network North" programme of conventional rail upgrades.

United States: California High-Speed Rail

California's HSR project — connecting San Francisco to Los Angeles and eventually San Diego via a 1,270 km network at 320 km/h — is simultaneously the most ambitious and most troubled HSR project in the Western world. First approved by voters in a 2008 referendum, the project has seen cost estimates balloon from an original $33 billion to current projections of $100–130 billion for the full system. Construction of the initial Central Valley section (Bakersfield to Merced, 119 km) is underway, but the politically and geographically challenging mountain crossings into Los Angeles and the Bay Area remain unbuilt and unfunded.

Supporters argue that when complete, the system will transform California's travel patterns and serve as a catalyst for HSR elsewhere in the US. Sceptics point to decades of overruns and political dysfunction. A new administration in 2025 has further complicated funding prospects. The Central Valley segment is now expected to open no earlier than 2033.

Japan: Chuo Shinkansen Maglev

Japan is building a train that operates on an entirely different physical principle from all other commercial rail. The Chuo Shinkansen uses magnetic levitation (maglev) technology — trains float above a guideway on a cushion of superconducting magnetic force, eliminating wheel-rail contact and its associated friction and wear. The result is a design speed of 505 km/h, with commercial operation planned at around 500 km/h.

The full route, from Tokyo (Shinagawa) to Osaka via Nagoya, is 438 km. The Nagoya section is furthest advanced: 86% of tunnels in Yamanashi and Nagano prefectures are complete. The Shizuoka Tunnel — the most controversial and geologically sensitive section — remained stalled for years due to concerns about its impact on local river systems; construction has begun following political resolution in 2024. JR Central now targets a Tokyo–Nagoya opening by 2034, with the full Tokyo–Osaka service by 2045.

Commercial maglev trains will cover Tokyo–Nagoya (286 km) in just 40 minutes — compared to 85 minutes on the fastest current Shinkansen — and Tokyo–Osaka (504 km) in 67 minutes.

India: Mumbai–Ahmedabad High-Speed Rail

India's first true HSR project is a 508 km corridor between Mumbai and Ahmedabad, using Japanese Shinkansen E5 technology and funding under a Japanese Official Development Assistance loan of ¥1.5 trillion. Maximum design speed: 320 km/h; planned journey time: approximately 3 hours (versus 7–8 hours by current express). Construction began in 2020 and is substantially advanced in Gujarat state; the Maharashtra section, including a challenging underwater tunnel in Mumbai harbour, has faced delays. A partial opening of the Gujarat section (Surat–Bilimora) is targeted for 2026, with the full route by 2028.

Morocco and Africa

Africa has already entered the HSR era: Morocco's Al Boraq line, connecting Casablanca and Tangier via Kenitra and Rabat, opened in November 2018. At 320 km and 320 km/h top speed, it is the first HSR line on the African continent. Operated with Alstom's Euroduplex double-deck TGV trains, Al Boraq reduces the Casablanca–Tangier journey from 4h45 to 2h10. Morocco has plans to extend the network south towards Marrakech and to upgrade Casablanca–Agadir conventional lines.

Egypt is studying an HSR network connecting Cairo with Alexandria and the Suez Canal zone, and several sub-Saharan African nations have conducted feasibility studies, though genuine construction is not imminent elsewhere on the continent.

Indonesia: Jakarta–Bandung (Whoosh)

Indonesia became Southeast Asia's first HSR operator when the Jakarta–Bandung Whoosh opened in October 2023. The 142 km line, built by a Chinese-Indonesian consortium using Chinese CRH technology, connects the Indonesian capital with Bandung in just 40 minutes — versus 3+ hours by road. Despite a challenging construction process and cost overruns, the project demonstrates that emerging economies can successfully deploy HSR technology with Chinese partnership financing.

New European HSR Plans

The European Commission's goal of tripling HSR passenger numbers by 2050 is driving a wave of new projects:

• Fehmarnbelt Tunnel (Germany–Denmark): Opens 2029, enabling Hamburg–Copenhagen HSR in ~2h30
• Lyon–Turin Base Tunnel (France–Italy): 57 km tunnel under the Alps, opening 2030+
• Rail Baltica (Estonia–Latvia–Lithuania–Poland): 870 km HSR connecting Tallinn to Warsaw, expected 2030
• Stuttgart 21 (Germany): New underground through-station enabling faster connections; completing 2025
• Brenner Base Tunnel (Austria–Italy): 55 km Alpine tunnel, passenger services from 2032

Southeast Asia and the Middle East

The global HSR expansion increasingly focuses on Southeast Asia and the Gulf. Following Indonesia's Whoosh success, Vietnam has approved a 1,545 km Hanoi–Ho Chi Minh City HSR line at an estimated cost of $67 billion — one of the largest infrastructure projects in Southeast Asian history. Construction is expected to begin in the late 2020s using Japanese and European technology, with completion targeted for 2040. Thailand, Malaysia, and the Philippines all have HSR studies underway, though funding and political commitment remain uncertain.

In the Gulf states, Saudi Arabia's Haramain High-Speed Railway — connecting Mecca and Medina via Jeddah and King Abdullah Economic City — has been operational since 2018, carrying Hajj pilgrims and regular passengers at 300 km/h across 453 km of desert. Saudi Arabia is now planning a broader national HSR network connecting Riyadh, Jeddah, and the Red Sea coast. Qatar's metro network, built for the 2022 World Cup, includes a planned intercity rail link to Saudi Arabia. The UAE's Etihad Rail freight network is being designed to eventually accommodate passenger services.

Hyperloop: Status Check

After years of hype, the hyperloop industry has undergone a sharp contraction. Virgin Hyperloop dissolved its US passenger development programme in 2022. Hyperloop One (backed by Richard Branson) shut down entirely in December 2023. European firm Hardt Hyperloop and others continue small-scale development in the Netherlands, but commercial hyperloop service by 2030 — once predicted confidently by entrepreneurs and feature writers — appears extremely unlikely. The consensus among transport engineers is that HSR at 320–400 km/h remains a far more deliverable technology for the realistic future of mass high-speed land travel. The vacuum-tube concept faces fundamental engineering challenges (pressure maintenance over hundreds of kilometres, emergency evacuation procedures, the enormous energy cost of maintaining near-vacuum) and economic challenges (per-km infrastructure costs estimated to exceed HSR by 3–5 times) that wheel-on-rail high-speed trains do not. The money and political will flowing into HSR worldwide in the 2020s and 2030s reflects this pragmatic assessment: the bullet train, not the hyperloop, is the technology of the near future.
