The Japanese bullet trains ______ .

For years now, the world’s fastest trains, operating in Japan and France, .have been stuck at a maximum operating speed of around three hundred kilometers an hour--in fact the latest Japanese bullet trains travel a bit slower than their predecessors, the emphasis of the designers being more on smoothness and economy. Now JR East, the country’s largest railway company, has unveiled a much faster train, capable of sustained speeds of around 360 kilometers an hour.
     The new train, which has been displayed in a dazzling teal color, looks very similar to the streamlined models already running on Japan’s high-speed railways, except for one unusual feature--extra emergency brakes in the form of cat’s ears--this, a response to the derailment of a bullet train after an earthquake last year.
