Each instrument base (3, 4) has a laser projector (7, 9) and a camera assembly (8, 10) longitudinally spaced apart along the instrument base (3, 4). A processing system (16) is arranged to process an overview image from an overview camera (11) for locating the contact wires (2a, 2b) and to control positions of first and second mirrors (13, 15). First and second detail cameras (12, 14) capture detail images from the first and second mirror (13, 15) of projected first and second transverse laser line (TL1, TL2) by the laser projectors (7, 9) on the contact wires (2a, 2b).",
