Europe boasts one of the world’s most extensive high-speed rail networks, with multiple countries operating trains at speeds of 200–320 km/h. As of 2025, Spain has the largest high-speed network in Europe (approximately 3,973 km of lines, followed by countries like France, Germany, and Italy. High-speed services have become integral for intercity travel across Western and Central Europe, often linking major cities in under 3–4 hours and providing a competitive alternative to air travel on those routes. Many lines are also interoperable across borders, enabling international high-speed services (for example, trains running between France, Belgium, the Netherlands, Germany, and the UK). Reservations are typically required or recommended on most high-speed trains (especially in Western Europe), and ticketing is usually available through the operators’ websites or international booking platforms. Major hub stations – Paris Gare du Nord/Lyon, London St Pancras, Brussels Midi, Frankfurt Hbf, Madrid Atocha, Milan Centrale, etc. – serve as interchange points where different high-speed lines and services connect.

Western Europe

France and Benelux

France was a pioneer of high-speed rail in Europe and today has an extensive TGV network radiating from Paris. French high-speed lines (LGV – Lignes à Grande Vitesse) connect Paris to major cities: Paris–Lyon (~2 hours), Paris–Bordeaux (~2h 5m), Paris–Marseille (~3h 15m via Lyon), Paris–Lille (~1h) and more. These lines operate at up to 300–320 km/h with SNCF’s TGV InOui services (standard TGV trains) and Ouigo (low-cost, all-reserved TGV trains). Ticket reservations are mandatory on TGVs. Paris is the primary hub – it has multiple terminus stations for high-speed lines (Gare de Lyon for southeast routes, Montparnasse for west/southwest, Nord for north and Eurostar/Thalys, Est for east). Other TGV hubs include Lyon Part-Dieu (key interchange between north–south routes) and Lille Europe (connecting London/Brussels and domestic TGVs).

French TGV lines also extend internationally. TGV trains (branded TGV Lyria when jointly operated with Switzerland) link Paris with Geneva and Zurich (~3h 5m Paris–Geneva). Thalys (a high-speed service historically separate from TGV) links Paris, Brussels, Amsterdam, and Cologne. As of 2024–2025, Thalys is being merged into the Eurostar brand under a single Eurostar Group, but services continue on the same routes. Thalys/Eurostar trains run Paris–Brussels (~1h 22m) and onward to Amsterdam (~3h 20m Paris–Amsterdam) and Cologne (~3h 15m Paris–Cologne). These trains operate at up to 300 km/h on the dedicated HSL (High Speed Line) in Belgium and the Netherlands. Major interchange: Brussels Midi station, where Thalys (Eurostar Group) connects with Eurostar and ICE. Amsterdam Centraal and Cologne Hbf are other Thalys termini (Cologne also sees German ICE trains).

Eurostar is the high-speed service traversing the Channel Tunnel, linking the UK with France, Belgium, and the Netherlands. Eurostar runs from London St. Pancras International to Paris Nord (~2h 15m) and Brussels Midi (~2h) as core routes, with some services to Amsterdam (~3h 50m London–Amsterdam via Brussels). Eurostar trains (operated by Eurostar Group) run at up to 300 km/h on High Speed 1 in the UK and LGV Nord in France

All Eurostar travel requires advance booking and includes security/border controls. Reservation: Eurostar tickets are separate from continental rail passes and must be booked, with check-in deadlines ~30–45 minutes before departure due to immigration checks.

Belgium and the Netherlands have their own domestic high-speed lines primarily used by international services. Brussels–Liège–Aachen (HSL 3) and Antwerp–Netherlands (HSL 4/HSL-Zuid) are the corridors used by Thalys, ICE, and Eurostar. The Dutch HSL-Zuid connects Amsterdam and Rotterdam to the Belgian border; it is used by Thalys/Eurostar at 300 km/h and also by Intercity Direct domestic trains (at 160 km/h). The primary operators on these lines are the international consortia (Eurostar Group for Thalys/Eurostar) and domestic operators like NMBS/SNCB (Belgium) and NS (Netherlands) for the limited domestic high-speed services. Major hub in this region: Brussels Midi, where Thalys/Eurostar/ICE converge (passengers can connect between London, Paris, Amsterdam, and Cologne there).

New services/routes (Jul–Dec 2025): While France’s network in 2025 has no brand-new lines opening in this specific period, a significant service expansion is happening with Spain’s Renfe entering the French domestic high-speed market. In late 2024, Renfe (Spain) began running its own AVE trains from French cities: notably Paris–Lyon–Marseille and Paris–Barcelona routes.

United Kingdom

The UK’s high-speed rail infrastructure centers on the HS1 line (High Speed 1, also known as the Channel Tunnel Rail Link) which runs from London to the Channel Tunnel. Eurostar uses this line as described above. Additionally, domestic high-speed commuter services operate on HS1: Southeastern High-Speed trains run from London St. Pancras to towns in Kent (e.g. Ashford, Canterbury) at up to 225 km/h. For example, London to Ashford International takes as little as 38 minutes on the Javelin high-speed trains. These are operated by Southeastern Railway; while they are part of the UK rail network, a small high-speed supplement or specific high-speed ticket is required, and seat reservations are not mandatory (trains are commuter-style). The UK’s other mainlines are not classified as high-speed rail by continental standards (they are older lines with top speeds of 125 mph / 200 km/h). However, a major project High Speed 2 (HS2) is under construction. HS2 aims to link London with Birmingham and northern England on new 330 km/h lines. HS2 is not expected to open until late 2020s, so no passenger services on HS2 will be operating in 2025 – thus it is outside our July–Dec 2025 scope except as a future development. The key UK hub for high-speed services remains London St. Pancras Intl, where Eurostar and Southeastern high-speed originate. (Connections: at St. Pancras, one can change between Eurostar and domestic HS1 services or cross the street to King’s Cross for onward trains on classic lines.)

Major Hubs & Interchanges (Western Europe)

• Paris: A central node of Europe’s high-speed network. Paris’s stations connect multiple international routes – e.g. Gare du Nord (Eurostar to UK, Thalys to Benelux/Germany, TGV to northern France), Gare de Lyon (TGV south/east, Trenitalia to Italy, Renfe AVE to Spain), Gare Montparnasse (TGV west/southwest). Paris is a transfer point between domestic TGVs and international trains.
• Brussels: Brussels Midi/Zuid station is an interchange for Eurostar (to London) and Thalys/ICE (to Paris, Amsterdam, Cologne). It allows convenient cross-platform transfers between London-bound and Amsterdam/Cologne-bound high-speed trains.
• Lille Europe: An important hub in northern France where some London–Paris and London–Brussels Eurostar trains call, and where TGVs on the domestic LGV Nord line connect. Lille Europe enables transfers between UK-France services and French domestic TGVs (including a direct London–Lille–Marseille Eurostar/TGV combination service on certain days).
• London St. Pancras: Terminus for Eurostar and Southeastern HS; connected via nearby stations to other UK routes. It’s effectively the UK’s international high-speed gateway.
• Amsterdam & Cologne: Endpoints of Thalys; Amsterdam connects onward to Dutch domestic network and Cologne to German ICE network (e.g. Cologne–Frankfurt high-speed line).

By late 2025 these services fall under the single Eurostar Group brand, linking London with Paris, Brussels, Amsterdam, and Cologne
