Analysis and Validation of a General Expression for High-Speed Train Resistance

A general expression of resistance for a high-speed train is needed to obtain a resistance formula at a system design process. Resistance formulas of KTX-Sanchon and HEMU-430X was made with a general expression developed in France and Japan for a concentrated power train and a multiple power train. Resistance obtained by the formulas was compared with running test results. The computed resistance of KTX-Sancho and HEMU-430X does not agree with the running test results. However, considering the resistance increase, the general expression can be useful to make a resistance formula for a system design process.
