Worldwide network at 200 km/h and above — {{km}} km in service
High-speed rail lines worldwide — routes, per-country mileage and served stations. A broad definition (UIC/Wikipedia): a new line at 250 km/h or above, OR an upgraded line at 200 km/h or above; "planned" stays out of scope, since an announced route isn't yet a geographic fact.
Three cross-checked sources: the route from OpenStreetMap (segments ≥ 200 km/h), per-country mileage from the Wikipedia/UIC "List of high-speed railway lines" table, served stations from Wikidata (P81) filtered against the route. Map and ranking share the same 200 km/h threshold so the two never diverge.
Colour by class: gold for new-build (≥ 250 km/h), steel blue for upgraded (200-249 km/h).
China (50,000 km in service) alone has more high-speed rail than the entire rest of the world combined — a network built in under twenty years, while Spain (3,973 km), Europe's pioneer alongside France (3,516 km), took four decades to reach a fraction of that total.
