Barreling Down the Tracks.

Discusses how high-speed trains are offering a comfortable, convenient and fast alternative to flying. Backed by the European Union, a network of high-speed lines is appearing on the Continent, challenging the pre-eminence of the airlines. By 2020 almost every European capital will have a system of new or upgraded tracks. At the same time, national rail companies are joining forces to create transnational services and build a shared fleet. The enthusiasm is global. The Japanese, who introduced high-speed rail travel with bullet trains, are extending their network. China talks of a line between Shanghai and Beijing. In the United States, Amtrak's high-speed Acela line has cut the travel time between Washington, D.C., and New York, luring passengers off the air shuttles.
