In the present study, the wind pressure transients on platform screen door in island platform caused by a passing train are investigated numerically. The transient compressible 3-D full Navier-Stokes solution is obtained with actual operational condition of subway train and the moving mesh technique adopted for the train movement. To achieve more accurate results, detailed shape of train is included in a computational domain and the entrance and exit tunnel of platform are also modeled. Numerical analyses are conducted on three operational conditions of different velocity variation.
