Abstract: A railway wagon for moving sleepers including: a base structure having a platform and at least one carriage, a first conveyor carried by the platform and configured to move the sleepers along a feed direction, a second conveyor distinct from the first conveyor and also carried by the platform. The second conveyor has: a first portion extended above the platform within a lateral size of the latter, and a second portion extending outside lateral size of the platform and configured to move the sleepers outside the platform.

Abstract: A railway vehicle for moving material includes a first and a second railway wagon, each of which extend between respective first and a second end portion the first and second railway wagons engaged at the second end portion of the first railway wagon and at the first end portion of the second railway wagon, wherein the first and second railway wagons each include: a platform, a carriage, a conveyor carried by the platform and having an operating section configured to move the material along a advancement direction. The railway vehicle includes a connection device carried by at least one of the first and second railway wagons (and configured to define an intermediate section for connecting the operating sections of the conveyors of the first and second railway wagons.

Abstract: A tamping machine, particularly for regenerating railway ballasts, includes: a supporting frame, a vibrating tamping hammer pivoted to the frame, and a hydraulic actuator engaged with a thrusting portion of the tamping hammer. The actuator includes first and second axially aligned sections engaged with each other, one of which is engaged with the thrusting portion of the tamping hammer and the other section is engaged with an abutment portion. The first section is extendable while the second section is supplied by distributing means having an alternate cyclical operation for enabling the tamping hammer to vibrate. The second section is a jacket extending between a first and second longitudinal ends, and a piston slidingly movable inside the jacket. The jacket is closed at the first and second longitudinal ends; the piston exhibits an overall axial size defined by respective thrusting opposite faces of the piston itself, which is entirely contained inside the jacket.
