Abstract The present invention is directed toward a track geometry measurement systems for railways based on inertial measurements. In one aspect the track geometry measurement system, comprises a plurality of wheels operable to trail over a rail track, a frame coupled to the wheels and an inertial measurement unit (IMU) with a sensor coupled to the frame. A processor is configured to obtain a first measurement from the sensor at a first location and a second measurement from the sensor at a second location, and to determine a first difference between the first and second measurements. The IMU may include one gyroscope for measuring pitch, a second gyroscope for measuring roll, and a third gyroscope oriented to measure yaw.
