With the historical opening of the express rail in April 2004, Korea has joined the league of France, Japan, Germany and Spain and entered into the super high-speed train era, operating at speeds of 300km per hour. Opening of the express rail, which has been referred to as the biggest national policy project since the national foundation, will not only bring about enormous changes to the lives of Koreans by enabling them to reach anywhere in the country within three hours, but it will also have a huge influence on the economic, social and cultural aspects of the country. Fast, safe, convenient and environmentally friendly, the express rail is a product of the latest technology and will secure its position as the newest and most preferred method of transportation for the next generation.       Express trains are generally defined as trains that operate at, or over, speeds of 200km per hour. Shinkansen of Tokaido, Japan (Tokyo ~ New Osaka) was the first train in the world to reach 210km per hour in 1964. Since then, express trains have developed rapidly, with many countries focusing on technological improvements to enhance the speed. Which, has resulted in the current production of trains that are capable of operating in excess of 300km per hour.
