Abstract：After a concise introduction to the track transitions and the theory of vehicle-track cou?pling dynamics,the vehicle/track interactions on the ballast track and ballastless track transition section are systematically analyzed in this paper. The evaluation, indexes are chosen,and a new method, called critical transition scot ion length,is put forward in determine track transition section length.
