The invention concerns a method for renewing a portion of railway track, characterised in that it consists of the following steps carried out in the following order: - renewing the sleepers and ballast during the same step, - renewing the rails. The method can comprise three periods of work for a given area: - a first period of work during which the sleepers and ballast are renewed, - a second period of work during which additional ballasting is carried out in order to adjust the height of the track, - a third period of work during which the rails are renewed.
The invention relates to a ballast clearing machine (302) that can remove worn ballast from a railway track and reload new ballast onto said track, said ballast clearing machine comprising a first and a second end, comprising means for removing all or part of the worn ballast and receiving new ballast on the same end. The invention also relates to a ballast renewing train comprising at least one ballast clearing machine (302) that can be coupled by just one of its ends, especially the rear end, to a set (301) of carriages for transporting granular material. The invention further relates to a method for renewing ballast of a portion of a railway track, using the same machine for removing the ballast and unloading ballast onto said portion of railway track.
E01B 27/10 - Renewing or cleaning the ballast in situ, with or without concurrent work on the track without taking-up the track
E01B 27/11 - Renewing or cleaning the ballast in situ, with or without concurrent work on the track combined with concurrent renewal of track components
E01B 29/06 - Transporting, laying, removing, or renewing sleepers
The invention also relates to a method for constructing a railway track (V1), comprising the steps consisting in: pouring a track slab (3) on a foundation slab (2); making two parallel longitudinal notches (5a, 5b) in each track, from the upper surface (3a) of the track slab; and securing a rail (11a, 11b) in each notch, each rail comprising a rail base (12) topped with a rail head (13) and a flap (14), said rail head and flap defining therebetween a groove (15), said rails (11a, 11b) not including webs. Advantageously, the height of the rails is less than or equal to half of the width.
The invention relates to an aggregate-transporting car (300) comprising: an aggregate car body (310), said car body including at least one aggregate outlet; and at least a first aggregate-transporting means (320) which extends longitudinally along the upper portion of the car body. The invention also comprises at least a second aggregate-transporting means that extends longitudinally under the car body. The transporting means can each comprise a conveyor belt. The invention also relates to a set of such cars and to a group of cars having common first and second longitudinal aggregate-transporting means.
The invention relates to a railway car (100) for placing long rails onto a railway platform, comprising a rear end (200) hitched to a rail transport car and a front end (400) and further comprising, on the rear end (200) thereof, at least one means (202a, 202b) for longitudinally removing a rail from a rail storage arranged on said rail transport car and at least one first means for driving the rail such as to move said rail to the front of said car.

The method also comprises the placement of rails on said crosspieces. The rails are pushed in front of a placement car for the first track (V1) and are deposited by sliding same out of a rail storage and placement train in a direction to the rear of the train and skewed in relation to the axis of the train for the second track (V2).
The invention relates to a method for constructing a railway track (VI) on a bed (5), comprising the following steps: removing at least one rail (R12) in front of a train used to store and lay rails, in the axis of said train, using removal means secured to the train, said train being stopped on a first, already constructed, portion of said track under construction (VI); and moving the at least one rail (R12) at least indirectly onto cross-members of said track under construction, so as to construct a second portion of said track as an extension of the first portion. The invention also relates to a method for constructing a first (VI) and second railway track on a bed, and to a method in which a first track portion (VI) and then a second track portion are alternately constructed by means of the same train used to store and lay rails while moving forward along an already constructed portion of a first track (VI).
