2112122 9300477 PCTABS00019 The object of the invention is a method for changing railway sleepers. In this method the sleepers (2) of the rails (1) are removed and new sleepers (3) are put in place. By using a lifting device (4) the rails (1) are lifted, at the same time they are loosened from the sleepers, the sleepers (2) are removed from under the rails and new sleepers (3) are brought under the rails and the railway ground is levelled by using a plough (5) which is placed under the rails (1) and which is pulled by the working machine (6). In addition, the object of the invention is equipment which permits the application of the method. At present, changing sleepers is slow and it requires much time to move equipment on to and off from the line. In the method, according to the invention, the plough (5) is used as a foundation base on which the rails rest during the work, and the plough can be left under the lifted railway section when the work has to be interrupted so that trains can run over it. In the equipment, according to the invention, the working machine (7) has supporting stands (11) which support it when it is lying on top of the rails, and during the work the working machine and the plough have been arranged to support the railway line.
