As talk hots up in India about superfast trains linking its big cities, it would do well to recall the first and the most iconic of fast commercial train lines, the Japanese Shinkansen expresses what the world fondly calls the &lsquobullet train&rsquo. A symbol of Japan&rsquos rise as an Asian economic superpower barely a decade after the devastation caused by WWII, the Shinkansen trains (Shinkansen is Japanese for New Trunk Line) were first developed by Japan National Railways in the late 1950s. Designed ingeniously, these trains could reach a then-stupendous 145kmph. The construction of the first of these lines, the Tokyo Shinkansen linking the capital to the industrial city of Osaka, began in 1959, and the first train was flagged off to mark the beginning of the 1964 Tokyo Olympics.
