A track-guiding device for vehicles for travelling on roads and rails using pneumatic tyres has in each case one guide device which is assigned to the front wheels and the rear wheels of the vehicle, can be moved out of a position of rest into a working position and has guide rollers which, in the case of rail travel, bring about the guidance of the vehicle on the rails, and are provided with wheel rims and are mounted so as to be deflectable by an amount equal to the radius of the track, the assigned front wheels and/or rear wheels of the vehicle being moved, via in each case one actuation device which is controlled as a function of the deflection of the guide rollers, from the respectively assumed position in the direction of the actual centre position, determined by the distance between the rail heads of the rails of the track, in proportion to this deflection in order to correct the centre position of wheel and rail head; cf. Figure 1. <IMAGE>
