The invention relates to a method for the progressive alignment of tracks in the track direction, especially curved tracks, using three interconnected ones, on the track with constant distance of movable carriages, of which the middle one carries an arrow height measuring device, with the arrow height between the track and one between the front and the rear Carriage tensioned, serving as a reference line wire or the like member is measured and in which the measured actual value is compared with the target value of the arrow height and as soon as there is a difference it is determined that the track is moved so far that the actual and target values match.

In a previously known method of this type, only the rear carriage is on the already aligned track and the track on the middle car is moved, which is on this Middle car located arrow height measuring device od against the stationary wire. Like. Moves. In this arrangement, inaccuracies result from the fact that the imprecise position of the front end the reference straight line, which is located in the not yet aligned track, is included in the measurement result.

It is also already a method for aligning tracks in terms of height on the basis of a Reference straight line has become known, in which initially the target position of individual points of the track to be aligned determined and the difference between this target position and the actual position of the track is determined and then the Reference line is arranged so that its rear end is located on an already in target position Location of the track, while its front end is in the as yet unaligned track area is in the predetermined target position, whereupon on the basis of the position corrected in this way Reference line the track is aligned. With this method, the reference line becomes embodied by a rigid longitudinal member of a chassis. The length of this carrier is natural limited, and for this reason alone the method is not suitable for aligning track curves to the side. With this method, too, the track is roughly in the middle of the reference straight line moved to its target position. There are two operators to bring the reference line into the corrected position provided, namely one at the front end of the reference straight line, which this front Bring the end into its target position for the time being, and one at the rear end of the reference line to compensate possibly still existing faults in the position of the rails.

After all, it is already known to align a track at the front end of a reference line, which is supported at its rear end and in its center on the already aligned track. A protruding rigid cantilever arm is used as the reference line, which is connected to a free one at the front End arranged track lifter interacts and remains at rest when straightening. Naturally, can this cantilever arm only extend over a relatively short length of track; for aligning For curved tracks, this facility is unsuitable from the start.

The most essential feature is based on a method of the type mentioned at the beginning of the present invention is that the track, while the rear car and the middle Car on the already aligned track is moved on the front car, whereby the the front end point of the reference straight line is shifted laterally accordingly and the reference straight line is opposite the dormant arrow altimeter is moved.

With this method, those inaccuracies that result from an imprecise position of the front end of the reference line could result, avoided. It is sufficient to carry out the procedure

an operator at the front car who shows track point 3 with position deviations after the arc setting of the respective target value of the arrow height on the outside or inside. In the event of such an error on the middle wagon due to a lateral shifting of the track point 3, the track at the front end point of the reference straight line is moved at this point until the chord S ₁ passes through it relative to the front wagon. The reference straight line anchored at 5 front end point together with the track on the wagon can be pushed, through which the points go and thus over a relatively long section of the target position of the track at point 3.
Extend the track, so that in the course of this step, a good error compensation must be achieved with every change in the track curvature; Track point 2 a different nominal value / the arrow height, in particular, the method is therefore set for the off io, ie the points transverse to the track are suitable for curved track. be pushed.
