The paper summarizes start， growth， accumulation， development，improvement， and leadership of the research on aerodynamics of high-speed rails in China， which focuses on train aerodynamics， vehicle-track-bridge-tunnel coupling aerodynamics， vehicle-wind-sand-rain-snow environmental aerodynamics， pantograph-catenary aerodynamic and body aerodynamics. It is devoted to finding the mechanism of formation， building fundamental theorem， creating technical breakthrough， proposing measures to tackle aero dynamical problems which pose a threat to development of high-speed railways and safety of operation， and realizing their engineering application. The paper introduces a series of experimental platforms for testing aerodynamics of high-speed rails and novel experiments we have accomplished， including moving vehicle model tests， human comfort/vehicle body stiffness/air tightness tests under alternating pressure， aero dynamical experiments in wind/sand/rain/snow coupling environment， vision inspection systems， experimental platform for full-scale vehicles， private/public wind tunnel and high-availability clusters for numerical simulation. Finally it discussed the ongoing research and our thoughts about further development.
