Quick answer: 1. China, 2. Spain, 3. Japan, 4. France, 5. Germany, 6. Italy, 7. South Korea, 8. Turkey, 9. Saudi Arabia, 10. Austria.
High-speed rail — typically defined as dedicated passenger railways operating at speeds of 250 km/h (155 mph) or higher — has reshaped travel in countries that invest in it. This list ranks the world's ten countries with the longest operational high-speed rail networks, using the latest data from the International Union of Railways (UIC). The ranking is dominated by China's staggering buildout, which in under two decades has become the world's largest high-speed network by a wide margin. The rest of the top ten is a mix of early adopters (Japan, France, Germany) and fast-growing networks in Spain, Italy, and emerging markets like South Korea and Turkey.
China operates by far the world's largest high-speed rail network, at roughly 47,000 km of dedicated HSR track. The network has expanded at an extraordinary pace since the Beijing–Tianjin line opened in 2008, now connecting most major Chinese cities with trains reaching 350 km/h on the newest trunk lines.
Spain has the second-longest HSR network in the world and the longest in Europe, at roughly 4,200 km. The AVE network connects Madrid with Barcelona, Seville, Valencia, Málaga and beyond, largely built to standard gauge (1,435 mm) rather than Spain's traditional Iberian broad gauge.
Japan's Shinkansen network spans roughly 3,100 km, making it the third-largest HSR system. The world's first high-speed rail line — the Tōkaidō Shinkansen between Tokyo and Osaka — opened in 1964, and the network has steadily expanded to cover Honshu, Kyushu, and Hokkaido.
France's Lignes à Grande Vitesse (LGV) network extends roughly 2,800 km, making it Europe's second-longest network. The LGV Sud-Est (Paris–Lyon), which opened in 1981, was Europe's first high-speed line, and TGV services now radiate from Paris to most French regions and cross-border destinations.
Germany's ICE (InterCity Express) network comprises roughly 1,700 km of high-speed track and a broader 2,400 km of upgraded conventional lines. Unlike France's hub-and-spoke LGV model, Germany's HSR is more interwoven with its conventional rail system, with ICE trains using both dedicated high-speed sections and upgraded legacy tracks.
Italy's Alta Velocità (AV) network extends roughly 1,100 km of dedicated high-speed track, with a Turin–Milan–Bologna–Florence–Rome–Naples spine as its backbone. Le Frecce and Italo services compete on the main routes, making Italy one of the few countries with genuine HSR competition.
South Korea's KTX (Korea Train Express) network spans roughly 900 km of dedicated high-speed track, connecting Seoul with Busan, Mokpo, and Gangneung. The system opened in 2004 using French TGV-derived technology and has since expanded with the second-generation KTX-Sancheon trains.
Turkey's Yüksek Hızlı Tren (YHT) network has grown to roughly 730 km, connecting Ankara with Istanbul, Konya, and Sivas. Turkey is one of the few non-European countries building HSR to European standards, with an ambitious expansion plan targeting several thousand more kilometres.
Saudi Arabia's Haramain High-Speed Railway spans roughly 450 km, connecting Mecca, Medina, Jeddah, and King Abdullah Economic City (KAEC). It is the Middle East's first and only high-speed rail line, operating at up to 300 km/h with Spanish Talgo trainsets.
Austria's high-speed network, estimated at roughly 380 km, is centred on the Wien–Linz–Salzburg Westbahn and the Semmering Base Tunnel corridor. While its sheer HSR length is modest, Austria has invested heavily in upgraded lines that allow Railjet services to operate at 230 km/h on key segments.
| # | Name | Continent | Maximum test speed | Year HSR began |
|---|---|---|---|---|
| 1 | China | Asia | 486 km/h (CR400 Fuxing) | 2008 |
| 2 | Spain | Europe | 404 km/h | 1992 |
| 3 | Japan | Asia | 443 km/h | 1964 |
| 4 | France | Europe | 574 km/h (record, 2007) | 1981 |
| 5 | Germany | Europe | 406 km/h | 1991 |
| 6 | Italy | Europe | 394 km/h | 1998 |
| 7 | South Korea | Asia | 421 km/h | 2004 |
| 8 | Turkey | Asia/Europe | 300 km/h | 2009 |
| 9 | Saudi Arabia | Asia | 335 km/h | 2018 |
| 10 | Austria | Europe | 275 km/h | 1994 |
Countries are ranked by total operational high-speed rail route length in kilometres, as reported in the International Union of Railways (UIC) High Speed Rail 2025 report. The UIC defines high-speed lines as dedicated tracks designed for 250 km/h or higher, or upgraded conventional lines capable of 200 km/h or higher. Where the UIC figures are preliminary or incomplete, individual national railway operator reports and country-specific sources are used as supplements. Rank 1 is the country with the longest total operational high-speed rail network.
China has by far the longest high-speed rail network, at roughly 47,000 km of dedicated HSR track — more than 10 times the length of second-place Spain. China's network has grown at an extraordinary pace since the first line opened in 2008.
The International Union of Railways (UIC) defines high-speed rail as dedicated tracks designed for 250 km/h (155 mph) or higher, or upgraded conventional lines capable of 200 km/h (124 mph) or higher. The UIC publishes an annual compendium of member countries' HSR networks using this definition.
Japan launched the world's first high-speed rail system in 1964 with the Tōkaidō Shinkansen (Tokyo–Osaka), operating at 210 km/h initially. France followed in 1981 with the LGV Sud-Est (Paris–Lyon), which was Europe's first dedicated HSR line.
The United States does not appear in the top ten because it currently has no operational dedicated high-speed rail line meeting the UIC definition. The Acela service in the Northeast Corridor reaches up to 241 km/h (150 mph) on short segments, but operates primarily on shared tracks and is generally classified as higher-speed rather than high-speed rail.
