The invention discloses a coordinate measurement system for track lines. The coordinate measurement system comprises a total station, a track inspection car and a processing unit. The total station erected on a track line is used for measuring three-dimensional coordinates of CP III points. The track inspection car running on the rack line is used for measuring line shapes between two corresponding line marking points of the two CP III points on the track line, and measuring horizontal distance and height difference values between the two line marking points and the two corresponding CP III points. According to the three dimensional coordinates of the two CP III points, geometrical relationships between the horizontal distance and height difference values between the two CP III points andthe corresponding line marking points thereof on the track line, and the line shapes between the corresponding line marking points of the CP III points on the track line, the processing unit solves three-dimensional coordinates of the corresponding line marking points of the CP III points on the track line by importing measurement data of the total station and the track inspection car. By the coordinate measurement system, the technical problems of labor and time consumption and low measurement accuracy of existing track line coordinate measurement methods can be solved.
