The flange climb derailment of railway vehicle is caused by the phenomenon that the wheels climb up the rail when the lateral force gets excessive. In particular, the turnout has a structure that the flange climb derailment is likely to occur compared with the general track. In this paper, the running safety of turnout sections is analyzed using the multi-body dynamics analysis tool. As the results, it is showed that the first wheelset on the turnout of trailing direction should be especially noted in terms of the value of the wheel rise. It is also confirmed that the larger the friction coefficient is, the larger the value of the wheel rise.
