A method and device for use in the installation of railway tracks. When laying out long rails for the installation of railway tracks it is desirable that the position of the rails on e.g. transport trucks be controlled and if necessary corrected to match the desired position of the rails on the formation. This will occur if a number of rollers (1) are adjusted in relation to each other and to the roller which is closest to the desired position on the formation. This is achieved by mounting the roller (1) in a yoke (2) fitted with an axle (3) mounted adjustably in a special beam (5). The attitude of the roller in relation to the beam can be locked by means of a suitably designed mechanism (6 and 7). To permit the movement of rails between two rollers, the rollers are made with somewhat rounded edges. For the better mobility of the invention the roller (1), yoke (2) and axle (3) are constructed as a detachable unit. The associated mechanism (6) for locking the roller (1) in the desired attitude is detachable from the axle (3).
