The Return of Trains: High-Speed Rail Networks Transforming Regional Travel

High-speed rail is experiencing a global renaissance as countries invest in alternatives to short-haul flights and car travel. China operates the world's largest HSR network (45,000+ km, 350 km/h). Japan's Shinkansen carries 450M+ passengers annually with zero fatalities. Europe's network connects major cities: Paris to London in 2h15m, Madrid to Barcelona in 2h30m. The US is finally building: California HSR (under construction), Texas Central (Dallas-Houston in 90 minutes), and Brightline (expanding in Florida). India's first HSR (Mumbai-Ahmedabad) is under construction. HSR produces 90% less CO2 than short-haul flights and 80% less than cars per passenger-km. The economics work for distances of 200-800 km where HSR competes effectively with both aviation and road travel.
