Abstract: A method for constructing a railway track (VI) on a bed (5), includes: removing at least one rail (R12) in front of a train used to store and lay rails, in the axis of the train, using removal elements secured to the train, the train being stopped on a first, already constructed, portion of the track under construction; and moving the at least one rail at least indirectly onto cross-members of the track under construction, so as to construct a second portion of the track as an extension of the first portion. A method for constructing a first and second railway track on a bed, and a method in which a first track portion and then a second track portion are alternately constructed with the same train used to store and lay rails while moving forward along an already constructed portion of a first track, are also described.

Abstract: A method for constructing at least one railway track (V1, V2) on a platform (5), wherein the permanent crosspieces are placed at the substantially permanent site thereof essentially through the use of railway vehicles (20, 30, 40). Crosspiece deposits are pre-formed on the platform (5) and along at least one track to be constructed (V1, V2) via railway vehicles. The method also includes the placement of rails on the 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).
