Through the external flow analysis of 200 km/h high-speed container flat wagon utilizing SST k- turbulence model, we got the surface pressure distributions, flow field, locomotive resistance, containers resistance and so on. The researches show that pressure drag dominates large resistance of high-speed container flat wagon; the size difference between locomotive and container as well as the gap between vehicles will complex the flow in return increase the total aerodynamic resistance of train; due to the influence of bottom flow, the pressure drag of middle container with bogies is smaller than without, but still large.
