A measuring vehicle 1 for determining the actual track position in relation to the desired track position has a vehicle frame 2 supported on rail bogies 5 with a frame plane 3 extending parallel to a reference plane formed by the wheel contact points 4. An independently mobile satellite vehicle 22 may be connected for transit to the front end of the vehicle frame 2. The measuring vehicle 1 and the satellite vehicle 22 are designed such that their upper contours 12 are arranged below a boundary plane 13 which encloses an angle .alpha. of 5 to 10.degree. with respect to a reference plane formed by the wheel contact points 4 of the rail bogies 5. The boundary plane 13 here forms with the frame plane 3 in the front end of the measuring vehicle 1, in the working direction, a line of intersection 14 extending perpendicularly to the longitudinal direction of the machine and parallel to the reference plane. This low overall height enables the measuring vehicle 1 to be coupled for transit to a tamping machine 32, from which there is a clear view on to the track.
