The invention relates to a track geometrical state rapid precision measurement system. The system comprises a carrying platform and a measuring unit arranged on the carrying platform. The carrying platform is a rail car; the measuring unit comprises a control terminal, a data acquisition module, a total station and a sensor; the data acquisition module sends a measurement instruction to the sensor, receives, stores and synchronizes sensor data in a time mode, and sends acquired data to the control terminal in real time; and the total station observes CPIII control points arranged on the two sides of a line according to a measurement instruction of the data acquisition module, and transmits observation values of the CPIII control points to the control terminal. In the invention, a problem that measurement precision and measurement efficiency cannot be effectively balanced after the existing track measurement equipment is used for track maintenance is solved; and absolute control of theCPIII point can be considered, the rapid detection of the rail smoothness can be realized, effective balance between the measurement precision and the measurement efficiency can be achieved, and requirements of rail transit in China for rail maintenance at present are met.
