In a method for renewing sleepers of a track formed of rails and the sleepers, the placement of skids, which support a machine frame of a track-building machine on the sleepers, is preceded by the machine frame being intermediately supported on the sleepers. The two rails are then distanced from one another, while avoiding a breakage separation, in a track section that includes both the region of the skids and the intermediate support. After supporting the machine frame on the skids, the intermediate support is lifted off the sleepers and work is begun.

A system for securing a railway apparatus includes a support platform and a mechanism for securing the railway apparatus to the support platform, capable of switching from an unlocked state to a locked state. The securing mechanism has a guide rail, a trolley guided by the guide rail along a path which, when the support platform is in the loading position, is parallel to a reference plane, a device for immobilizing the trolley relative to the guide rail, an attachment member for attaching the railway apparatus secured to the trolley; and locking members for locking the guide rail relative to the support platform, which switch from an unlocked position to a locked position when the securing mechanism switches from the unlocked state to the locked state in the loading position of the platform, by urging the guide rail downwards relative to the support platform.

A tamping machine includes at least one first tamping unit with first tamping tools and a first hydraulic motor provided with a first drive shaft driving the first tamping tools so as to generate tamping movements, and a second tamping unit adjacent the first tamping unit with second tamping tools and a second hydraulic motor provided with a second drive shaft driving the second tamping tools so as to generate tamping movements. The first hydraulic motor and the second hydraulic motor are supplied with power by a common synchronized hydraulic power supply system.

A railroad renewal method includes, in particular: the removal of the old rail, the installation of the new rail and the primary adjustment of the temperature of the new rail to a set value at a point located upstream of and close to the attachment area on a crosstie. The thermodynamic behavior of the intermediate section of the new rail located between the primary temperature adjustment point and the attachment area is controlled by way of a device, provided with a control and management system, such that the temperature of the new rail is uniform, in the cross-section thereof, at a set value on the attachment point.

A machine for repairing a ballast bed has an undercutter that defines a direction of movement of the repairing machine, and a distributor for dividing a flow of ballast entering from the undercutter into a rear flow of exiting ballast and a separate front flow of exiting ballast. At least one rear screening machine is positioned behind the undercutter in the direction of movement and is fed by the rear flow of exiting ballast. At least one front screening machine is positioned in front of the undercutter and fed by the front flow of exiting ballast, and the distributor has a variator for varying the ratio between the separate first and the second flows of exiting ballast.

A machine for the renewal of sleepers of a track having rails and for the cleaning of exposed ballast after removal of old sleepers, includes a machine frame which is movable on a rail bogie on the track, a screening plant and a clearing device having a collection device for collecting ballast. A sleeper transport device includes a sleeper gripper, rotatable about a vertical axis, between two end-positioned rail bogies, connected to the machine frame, and being displaceable in a longitudinal direction of the machine. The sleeper transport device is displaceable from a front end position (with respect to a working direction) provided for picking up new sleepers by the collection device for collecting ballast, to a rear end position configured to deposit the new sleepers.
