Zipping cross-country in a super-high speed train has become commonplace in many countries these days, but it was unheard of when Japan launched its bullet train between Tokyo and Osaka 50 years ago Wednesday. The Shinkansen, as it's called in Japan, gave a boost to train travel in Europe and Asia at a time when the rise of the automobile and the airplane threatened to eclipse it. The first bullet train, with its almost cute bulbous round nose, traveled from Tokyo to Osaka in four hours, shaving two and a half hours off the 513-kilometer (319-mile) journey. The latest model, with a space-age-like elongated nose, takes just two hours and 25 minutes. The first Shinkansen had a maximum speed of 210 kilometers (130 miles) per hour. The fastest trains previously, in Europe, could reach 160 kph. Today's bullet trains, in Japan and elsewhere, have reached and in some cases exceeded 300 kph (186 mph). By average speed, China has the fastest train in the world, averaging 284 kph. Turkey last year became the ninth country to operate a train at an average speed of 200 kph. South Korea and Taiwan also operate high-speed systems in Asia. The fastest train in the U.S., Amtrak's Acela Express, averages 169 kph (105 mph) on a short stretch between Baltimore and Wilmington, Delaware. Shanghai launched a German-built maglev train in 2004 on a 30-kilometer route between the city and the airport. It can hit 430 kph (267 mph). A Japanese maglev train in development has topped 500 kph (310 mph) in tests.
