Turnout is one of important infrastructures in high-speed railway. In order to study the law of wheel-set lateral displacement when a train passes a turnout at high speed, a wheel-set lateral displacement test system is developed by using laser displacement sensors and a corresponding digital data collection system. The test system is verified to be reliable through a field test focusing on turnout No.18 of Hefei-Nanjing high speed railway in China. Meanwhile, the field test reveals the wheel-set lateral displacement law of EMUs(Electric Multiple Units) as they pass the turnout No.18 at different speeds and from different directions: when the EMUs pass the turnout at high speed, in sections of switch rail top width ranging 15~35mm and nose rail top width ranging 45~65mm, the wheel-sets produce lateral displacement rapidly; comparing two conditions, i.e. the EMUs pass the turnout from forward and from reverse direction, the wheel-set lateral displacement under former condition is bigger and it will cause a bigger lateral vibration acceleration.
