Abstract
Recently, Railway Systems are getting increased worldwide attention in order to reduce environmental pollution and traffic jam. The railway systems are Light Rail Transits in city or high speed railways between cities. Up to now, dynamic behavior of the vehicle running on a turnout at high speed wasn't researched. Dynamic behaivior of the vehicle running on turnout at high speed was calculated by this research. The developed simulation considered the longitudinal variation of crosssection of rail head with vehicle running on turnout (Tongue Rail and Crossing Rail). This paper shows dynamic simulation of the vehicle running on a turnout at high speed. And, the calculated results are also shown.
