The construction of the 411 km-long Seoul-Pusan high speed rail line began in June 30, 1992. The line connects Seoul and Pusan which are the first and the second largest cities in Korea. The line has two terminal stations and four intermediate stations. The maximum operating speed of the wheel-on-rail rolling stock on the line will be 300 km per hour. This paper shows how the optimum route and number of stations, among other system characteristics such as the maximum operating speed, were selected. Twelve route alternatives were scrutinized before the final selection of the route. In addition to the route alternatives, three maximum speed alternatives and many different stations were also analyzed. These three characteristics were analyzed in a combined form because these variables have impact on others. The development process of alternatives for routes, number of stations, and maximum speed is explained, followed by the description of the analysis process, such as patronage forecast and economic analysis for the combined alternatives. Results of economic analysis of the alternatives are also reported.
