A procedure for laying railway tracks on a trackbed on which sleepers (20) are located, that comprises at least the following steps: a) approach of a track laying train (30) with the stretches of rail (1) to be laid in the laying area; b) joining of the pairs of rails (1) to the consecutive rails (1) by means of tractor plates (200); c) unloading the pairs of rails (1) from the track laying train (30) onto the bed; d) squaring of the sleepers (20) by means of a squaring device; e) joining of the consecutive pairs of rails (1) by means of a joint plate (100); f) unloading of ballast in hoppers onto the bed; g) tamping of the rails (1); h) profiling of the ballast by means of a profiling device (400); i) welding of the rails (1).

A device for laying sleepers on a ballast-bed for railroad construction includes a body having a commuting-mechanism and a fork-lift on a first side of the body The fork-lift lifts and holds at least one set of sleepers above the ballast-bed. A pair of pivot-arms are movably coupled the body and include a gripper. The gripper moves a set of sleepers from the fork-lift from the first side of the body towards a second side of the body. A cradle-arrangement mounted on the second side of the body and the commuting-mechanism allow movement of the device. The pair of elongated fixed support-members is configured to support the set of sleepers moved by the grippers The pair of movable support-members has a reciprocating-movement with respect to the pair of elongated fixed support-members to successively release one sleeper of the set of sleepers at a time from the pair of elongated fixed support-members.

The purpose of the invention is a railway track (3) sleeper (2) squaring device and the machine which carries this device. The device comprises a first and a second positioning element (1) adapted to be located between pairs of sleepers (2) and for locating at opposite ends of the sleepers (2) and parallel to the direction of the railway track (3) where these positioning elements (1) can be extended in that direction with the first and second positioning element (1) being configured such that on extending them simultaneously to a pre-set value they push the sleepers (2) so as to produce squaring of these sleepers (2).
