The relative flow around two passing-by train models in double-bore railway tunnel with vertical ventilation were analyzed by Moving IBM(Immersed Boundary Method). The flow field in the vertical ventilation in the railway tunnel was also investigated. The tested car body was modeled by cylinder type body and relatively moved each other. On the other hand, the tunnel and vertical ventilation were fixed. The momentum equations were solved by LES method in FDS code developed by NIST. The initial condition of fluid in the railway tunnel was stationary. The Reynolds number is 1,500 based on the railway car radius. The turbulent flow field in the railway tunnel and vertical ventilation were qualitatively investigated
