Abstract

The train has a series of trucks, including three with pallets of new sleepers. One is for removing old sleepers, and one with two conveyors for old and new sleepers. It has a system for lifting the old rails and depositing them on either side of the track. A lower conveyor (13) is used for removing old sleepers (4) and an upper conveyor (15) for delivering new ones. It has an excavator for lifting part of the old ballast, and a system (18) for laying the new rails on the new sleepers (3). The layer (16) for the new sleepers is situated behind the lower section of the ballast excavator, so that the new sleepers are positioned across the track and laid on a remaining bed of ballast. The new rails are then fixed to the sleepers and the excavated ballast is redistributed between them.

Description

La présente invention concerne le domaine du renouvellement des voies ferrées.The present invention relates to the field of renewal of railways.

Le renouvellement consiste à remplacer le matériel des voies (rails et traverses) ainsi que le ballast qui assure la tenue de la voie sur sa plate-forme.Renewal consists of replacing the equipment tracks (rails and sleepers) as well as the ballast which keeps track on its platform.

Au cours de la vie d'une voie ferrée, tant le matériel que le ballast sont soumis à des contraintes, érosions et pollutions qui amoindrissent sa qualité et nécessitent, à terme, un remplacement.During the life of a railway, both the material that the ballast is stressed, erosions and pollution that reduce its quality and eventually require replacement.

Compte tenu des impératifs commerciaux de l'exploitant de la voie ferrée, il n'est pas envisageable d'interrompre le trafic sur une voie en cours de renouvellement pendant toute la durée du chantier de renouvellement.Given the commercial imperatives of the operator of the railway, it is not possible to interrupt traffic on a lane in progress renewal throughout the duration of the renewal.

C'est pourquoi les contraintes imposées aux entreprises qui exécutent ces travaux de renouvellement comportent une limitation de la durée des interruptions de trafic avec une reddition journalière de la voie en fin de poste, les convois pouvant circuler sur la voie en cours de renouvellement à une vitesse plus faible qu'en cours d'exploitation normale tant que la voie n'a pas été entièrement consolidée au terme de l'opération de renouvellement.This is why the constraints imposed on companies carrying out these renewal works include a limitation on the duration of interruptions traffic with daily lane surrender at the end of post, the convoys being able to circulate on the way being renewal at a lower speed than in progress normal operation until the track has been cleared fully consolidated at the end of the operation of renewal.

Actuellement, lors de la reddition journalière, la vitesse commerciale autorisée sur une voie en renouvellement est de l'ordre de 40 à 60 km/h maximum.Currently, during the daily surrender, the commercial speed authorized on a track in renewal is around 40 to 60 km / h maximum.

Une opération typique de renouvellement met en oeuvre des trains spécialisés comportant des machines aptes à opérer en séquence les opérations suivantes :

  • le dégarnissage, criblage du ballast et l'évacuation des produits de dégarnissage, par bandes transporteuses sur wagons destinés à la décharge ou jet direct au remblai,
  • la substitution de la voie renouvelée (rails et traverses),
  • le ballastage et le relevage de la voie, le nivellement et le dressage,
  • le soudage des rails, la libération des contraintes, un nouveau nivellement-dressage, le réglage des banquettes et le nettoyage des accotements.
   (Cf Jean ALIAS, LA VOIE FERREE, Librairie EYROLLES, Paris 1984, page 368 et suivantes).A typical renewal operation uses specialized trains comprising machines capable of operating the following operations in sequence:
  • the stripping, screening of the ballast and the evacuation of the stripping products, by conveyor belts on wagons intended for the discharge or direct jet at the embankment,
  • the substitution of the renewed track (rails and sleepers),
  • ballasting and raising of the track, leveling and dressing,
  • the welding of the rails, the release of constraints, a new leveling-dressing, the adjustment of the benches and the cleaning of the shoulders.
(Cf Jean ALIAS, THE RAILWAY, EYROLLES Bookstore, Paris 1984, page 368 and following).

On connaít par le brevet EP 255 564 PLASSER un procédé de renouvellement de voie dans lequel le ballast de la voie à rénover est partiellement dégarni à l'aide d'une chaíne excavatrice à parcours triangulaire, de manière à ce que les traverses et les rails neufs soient déposés sur l'assise stabilisée, le ballast précédemment excavé étant immédiatement réemployé pour stabiliser les rails et les traverses neufs venant d'être déposés.We know by EP 255 564 PLASSER a lane renewal process in which the ballast of the path to be renovated is partially cleared using a excavator chain with a triangular path, so that that the new sleepers and rails be placed on the stabilized seat, the previously excavated ballast being immediately re-used to stabilize the rails and new sleepers just removed.

Toutefois, la machine décrite dans ce brevet pour la mise en oeuvre de ce procédé est complexe.However, the machine described in this patent for the implementation of this process is complex.

En effet, cette machine comporte un chassis en deux parties réglables en écartement, reposant sur la voie par trois trains de roulement (8, 9 et 15), le train de roulement intermédiaire étant rétractable de manière à ne pas être en contact avec le sol lors de son utilisation au-dessus de la coupe de travail (espace entre la voie ancienne et la voie renouvelée).Indeed, this machine has a chassis in two parts adjustable in spacing, resting on the track by three undercarriages (8, 9 and 15), the undercarriage intermediate bearing being retractable so as not to not be in contact with the ground when using it above of the working cup (space between the track old and the renewed way).

Pour cette raison, la machine en configuration de renouvellement (train intermédiaire rétracté) repose par son extrémité avant sur un pivot porté par le dernier wagon de la rame de tête précédant la machine de renouvellement proprement dite dans le train de renouvellement.For this reason, the machine in configuration of renewal (intermediate gear retracted) based on its front end on a pivot carried by the last wagon of the head train preceding the renewal machine proper in the renewal train.

De plus, dans la machine PLASSER la remise en voie du ballast excavé s'effectue immédiatement derrière le dernier train de roulement (9) de la machine de renouvellement, ce qui impose que la machine comporte des agencements spécifiques pour remplir cette fonction.In addition, in the machine PASS re-routing excavated ballast is carried out immediately behind the last undercarriage (9) of the machine renewal, which requires that the machine has specific arrangements for fulfilling this function.

Enfin et surtout, dans la machine PLASSER les traverses neuves (6) sont assurées par un transporteur (26) à une pondeuse (49) disposée en arrière du train de roulement intermédiaire (15).Last but not least, in the machine PASS the new sleepers (6) are provided by a transporter (26) to a layer (49) located behind the train intermediate bearing (15).

A cet effet, le transporteur (26) est agencé pour traverser la chaíne excavatrice (29) dans sa partie haute. Il en résulte que les traverses doivent passer longitudinalement à travers la chaíne excavatrice (29) et être ensuite pivotées sur elles-mêmes par un dispositif de retournement intégré à la pondeuse (49) pour que les traverses soient déposées transversalement à la voie.To this end, the conveyor (26) is arranged to cross the excavator chain (29) in its upper part. As a result, the sleepers must pass longitudinally through the excavator chain (29) and then be pivoted on themselves by a device reversal integrated into the layer (49) so that the sleepers are placed transversely to the track.

La présente invention a pour objet une machine de renouvellement de voie permettant l'excavation partielle du ballast et sa remise en voie après la pose des rails et des traverses neufs très simplifiée par rapport à la machine décrite dans le Brevet EP PLASSER 255 564.The present invention relates to a machine for track renewal allowing partial excavation of the ballast and its return to track after the installation of the rails and new sleepers very simplified compared to the machine described in EP PLASSER Patent 255 564.

Selon l'invention, le train de renouvellement de voie ferrée du type comportant des moyens d'enlèvement des traverses et des rails usés, des moyens permettant de réaliser une excavation partielle du ballast, des moyens de repose des traverses neuves et des rails neufs, et des moyens de redistribution totale du ballast excavé sur les rails et les traverses neufs, train du type dans lequel les moyens d'excavation du ballast sont constitués par une chaíne excavatrice sans fin à parcours triangulaire est caractérisé en ce que le dispositif de pose des traverses neuves (16) est agencé en partie basse de l'excavatrice (5) de manière que les traverses neuves (3) soient orientées transversalement à la voie lorsqu'elles passent à travers l'excavatrice.According to the invention, the renewal train of railway track of the type comprising means for removing used sleepers and rails, means for carry out a partial excavation of the ballast, means of installs new sleepers and rails, and means of total redistribution of the ballast excavated on the new rails and sleepers, train of the type in which the ballast excavation means consist of a endless triangular chain excavator east characterized in that the device for laying the sleepers new (16) is arranged in the lower part of the excavator (5) so that the new sleepers (3) are oriented transversely to the track as they pass through the excavator.

L'invention sera mieux comprise à l'aide de la description ci-après du train de renouvellement pour la mise en oeuvre du procédé ci-dessus décrit.The invention will be better understood using the description below of the renewal train for implementation of the method described above.

La description sera faite en référence aux dessins annexés dans lesquels :The description will be made with reference to the drawings annexed in which:

La figure 1 est une vue générale schématique du profil d'un train de renouvellement selon l'invention en cours de travail sur une portion de voie ferrée.Figure 1 is a general schematic view of profile of a renewal train according to the invention in course of work on a section of railway.

La figure 3 est une vue schématique en coupe de l'unité de substitution au point de croisement entre la pondeuse de traverses neuves et la chaíne dégarnisseuse du ballast.Figure 3 is a schematic sectional view of the unit of substitution at the point of intersection between the laying of new sleepers and the stripping chain of ballast.

La figure 4 est une vue agrandie de l'unité d'approvisionnement et d'évacuation de traverses du train de renouvellement représenté à la figure 1.Figure 4 is an enlarged view of the unit supply and evacuation of train sleepers renewal shown in Figure 1.

La figure 5 est une vue agrandie de l'unité de substitution et d'abaissement du profil de voie du train de renouvellement représenté à la figure 1.Figure 5 is an enlarged view of the unit of substitution and lowering of the track profile of the train renewal shown in Figure 1.

La figure 5bis est une vue schématique de dessus de la voie correspondant à la figure 5.Figure 5bis is a schematic top view of the channel corresponding to Figure 5.

La figure 6 est une vue de détail encore agrandie de la figure 5.Figure 6 is a further enlarged detail view in Figure 5.

La figure 7 est une vue agrandie de l'unité d'assemblage de voie du train de renouvellement représenté à la figure 1.Figure 7 is an enlarged view of the unit track assembly of the renewal train shown in Figure 1.

La figure 8 est une vue agrandie de l'unité de répartition et de nivellement du ballast du train de renouvellement représenté sur la figure 1.Figure 8 is an enlarged view of the unit of distribution and leveling of the ballast of the train renewal shown in Figure 1.

Les figures 9a à 9f sont une série de vues en coupe de la voie au fur et à mesure de la progression de la rame de renouvellement selon l'invention soit successivement :Figures 9a to 9f are a series of sectional views of the track as the train progresses of renewal according to the invention either successively:

Figure 9a : voie avant le renouvellement (traverses et rails usagés),Figure 9a: track before renewal (sleepers and used rails),

Figure 9b : plate-forme ballastée après enlèvement du matériel usé,Figure 9b: ballasted platform after removal used equipment,

Figure 9e : répartition du ballast excavé sur le matériel neuf,Figure 9e: distribution of the excavated ballast on the new equipment,

Figure 9f : profil de voie après nivellement et remise en forme.Figure 9f: track profile after leveling and fitness.

Les repères d'altitude PR sur ces vues en coupe montrent que le profil en long de la ligne est rétabli grâce au procédé selon l'invention dès la mise en place du matériel neuf sans qu'il soit nécessaire de remplacer le ballast.The PR altitude marks on these section views show that the profile along the line is restored thanks to the process according to the invention as soon as the new equipment without the need to replace the ballast.

Il est ici précisé que par train de renouvellement on entend non seulement les appareils liés mécaniquement entre eux pour former une rame mais également les appareils individuels, tels que la bourreuse niveleuse représentée à la figure 8, qui sans être forcément mécaniquement liée à la rame, interviennent sur la même portion de voie dans la même passe de travail.It is here specified that by renewal train we mean not only mechanically linked devices between them to form a train but also the devices individual, such as the grader tamper shown in Figure 8, which without necessarily being mechanically linked to the train, operate on the same portion of track in the same work pass.

Sur la figure 2 est représenté schématiquement le principe de substitution des rails au cours de l'avancement du train de renouvellement.In Figure 2 is shown schematically the principle of substitution of rails during advancement of the renewal train.

Les rails neufs, 1a et 1b, ont été préalablement déposés sur deux files de part et d'autre de la voie à renouveler dont les rails sont représentés par les références 2a et 2b.The new rails, 1a and 1b, have been previously deposited in two queues on either side of the track at renew whose rails are represented by references 2a and 2b.

L'axe de la voie est représenté sous la référence A. Le sens de déplacement du train de renouvellement, de la droite vers la gauche sur les dessins, est représenté par la flèche F.The axis of the track is represented under the reference A. The direction of movement of the renewal train, the right to left in the drawings, is represented by arrow F.

Les traverses neuves sont représentées par la référence 3, les traverses usées par la référence 4, le dispositif de dégarnissage par la référence 5. Ces divers éléments sont représentés plus en détail sur la figure 5bis.New sleepers are represented by the reference 3, the sleepers worn by reference 4, the stripping device by reference 5. These various elements are shown in more detail in the figure 5bis.

Sur la figure 1 on voit que les train de renouvellement pour la mise en oeuvre de l'invention est divisé en quatre unités fonctionnelles se succédant dans le sens de l'avancement F à savoir :

  • une unité d'approvisionnement et d'évacuation des traverses T, qui sera décrite plus en détail en relation avec la figure 4,
  • une unité de substitution, d'encoffrement et d'abaissement du profil, S, qui sera décrite plus en détail en relation avec les figures 3, 5, 5bis et 6,
  • une unité d'assemblage de voie, V, qui sera décrite plus en détail en relation avec la figure 7,
  • une unité de répartition du ballast, R, qui sera décrite plus en détail en relation avec la figure 8.
In FIG. 1, it can be seen that the renewal train for implementing the invention is divided into four successive functional units in the direction of travel F, namely:
  • a supply and evacuation unit for sleepers T, which will be described in more detail with reference to FIG. 4,
  • a substitution, encasement and profile lowering unit, S, which will be described in more detail in relation to FIGS. 3, 5, 5a and 6,
  • a track assembly unit, V, which will be described in more detail in relation to FIG. 7,
  • a ballast distribution unit, R, which will be described in more detail with reference to FIG. 8.

L'unité T (figure 4) comporte dans l'exemple représenté trois wagons de palettes de traverses 6, 7, 8, un wagon d'évacuation de traverses usagées 9 et un wagon 10 à double transporteur l'un pour les traverses neuves, l'autre pour les traverses usagées.Unit T (Figure 4) includes in the example represented three wagons of pallet sleepers 6, 7, 8, a used sleeper evacuation wagon 9 and a wagon 10 with a double transporter, one for new sleepers, the other for used sleepers.

Sur cet ensemble de wagons est disposé un chemin de roulement continu pour un portique 11 qui au cours de ses mouvements de va-et-vient prélève et retourne les traverses neuves dans leur palettes, les dépose sur le tapis supérieur du wagon 10, reprend au retour les traverses usagées accumulées sur le wagon 9 et va les déposer dans une palette libérée sur l'un des wagons 6, 7 ou 8.On this set of wagons is arranged a path of continuous rolling for a gantry 11 which during its back and forth movements take and return the sleepers new in their pallets, places them on the carpet top of wagon 10, takes the ties back used accumulated on wagon 9 and will deposit them in a pallet released on one of the wagons 6, 7 or 8.

L'unité S (figure 5) comporte schématiquement :

  • des moyens 12 pour soulever et écarter latéralement les rails usés 2 et les déposer de part et d'autre de la voie,
  • un transporteur inférieur 13 qui évacue vers le wagon 10 les traverses usagées 4 prélevées sur la voie libérée des rails usés 2 par un dispositif de dépose 14,
  • un transporteur supérieur 15 qui alimente une pondeuse 16 en traverses neuves 3 en provenance du wagon 10,
  • un dispositif excavateur 5 qui prélève le ballast dans la coupe réalisée entre la voie ancienne et la voie renouvelée et qui le dépose sur une pluralité de transporteurs bande 17, 17', 17" s'étendant au-dessus de l'unité V jusqu'au wagon à trémie de l'unité R (figures 7 et 8),
  • et des moyens 18 pour soulever et déposer les rails neufs 1 sur les traverses neuves.
The unit S (FIG. 5) schematically comprises:
  • means 12 for lifting and spreading the worn rails 2 laterally and depositing them on either side of the track,
  • a lower conveyor 13 which evacuates to the wagon 10 the used sleepers 4 taken from the track freed from the worn rails 2 by a removal device 14,
  • an upper conveyor 15 which supplies a layer 16 with new sleepers 3 coming from wagon 10,
  • an excavator device 5 which takes the ballast from the cut made between the old track and the renewed track and which deposits it on a plurality of conveyor belts 17, 17 ', 17 "extending above the unit V up to to the hopper wagon of unit R (Figures 7 and 8),
  • and means 18 for lifting and depositing the new rails 1 on the new sleepers.

Tous ces moyens sont bien connus des hommes de l'art et ne seront pas décrits plus en détail dans leur constitution et leur fonctionnement.All these means are well known to men of art and will not be described in more detail in their constitution and operation.

Toutefois, selon l'invention, la disposition particulière de la pondeuse 10 et de l'excavatrice 5 est un élément caractéristique permettant la mise en oeuvre du procédé nouveau, c'est pourquoi cette disposition est décrite plus en détail sur les figures 3 et 6.However, according to the invention, the arrangement particular of layer 10 and excavator 5 is a characteristic element allowing the implementation of the new process, this is why this provision is described in more detail in Figures 3 and 6.

On voit sur ces figures que l'excavatrice 5 est constituée par une chaíne symbolisée par les flèches 19 sur la figure 3, entraínée par un moteur 20 (figure 6) et circulant dans deux couloirs, dont un élévateur, 21, 22 formant un compas pour conférer à la chaíne 19 un parcours sensiblement triangulaire, la partie basse ouverte reliant les deux couloirs 21 et 22 constituant le front d'attaque 23 de la chaíne.We see in these figures that the excavator 5 is constituted by a chain symbolized by the arrows 19 on Figure 3, driven by a motor 20 (Figure 6) and circulating in two corridors, including an elevator, 21, 22 forming a compass to give chain 19 a path substantially triangular, the lower open part connecting the two corridors 21 and 22 constituting the attack front 23 of the chain.

On voit également sur cette figure que la pondeuse 16 s'étend à travers l'excavatrice 5 dans la partie basse des couloirs 21 et 22, et que les traverses sont orientées transversalement à l'axe de la voie.We also see in this figure that the layer 16 extends through the excavator 5 in the lower part corridors 21 and 22, and that the sleepers are oriented transverse to the axis of the track.

Cette disposition permet de simplifier considérablement les mécanismes de pose des traverses neuves par rapport à ceux des trains de renouvellement actuellement connus.This arrangement simplifies considerably the mechanisms for laying sleepers new compared to those of the renewal trains currently known.

En effet dans ces trains, les traverses neuves passent également à travers l'excavatrice mais, étant donné qu'elles passent en partie haute du compas formé par les couloirs de l'excavatrice, il est nécessaire de prévoir en avant et en arrière de l'excavatrice des dispositifs de retournement qui orientent les traverses une à une parallèlement à l'axe de la voie pour leur permettre de passer à travers l'excavatrice, puis les orientent transversalement pour les déposer sur l'appareil de descente qui les pose sur la plate-forme.Indeed in these trains, the new sleepers also pass through the excavator but, given that they pass in the upper part of the compass formed by the excavator corridors, it is necessary to provide in front and rear of the excavator reversal which orient the sleepers one by one parallel to the center line of the track to allow them to pass through the excavator and then orient them transversely to place them on the device of descent which puts them on the platform.

Grâce à la disposition illustrée sur les figures 3 et 6, la pondeuse peut être un simple plan incliné sur lequel les traverses glissent par gravité. L'extrémité basse est montée sur le châssis de la machine par l'intermédiaire d'un balancier de réglage en alignement et en dévers représenté schématiquement par la référence 24 sur la figure 6.Thanks to the arrangement illustrated in Figures 3 and 6, the layer can be a simple inclined plane on which the sleepers slide by gravity. The end low is mounted on the machine chassis by through an alignment balance and superelevation represented schematically by the reference 24 in figure 6.

L'unité V (figure 7), porte les moyens d'assemblage de la voie en renouvellement et se compose d'un wagon 25 d'approvisionnement de petit matériel (attaches, tirefonds, etc.) et d'un wagon 26 porteur de tirefonneuses mécaniques 27.Unit V (Figure 7), carries the assembly means of the track in renewal and consists of a wagon 25 supply of small equipment (fasteners, lag bolts, etc.) and a wagon 26 carrying mechanical spindles 27.

Chacun des wagons 25 et 27 porte en partie supérieure des convoyeurs 17', 17" qui transfèrent le ballast excavé vers l'unité de répartition et de nivellement R.Each of wagons 25 and 27 partly carries upper of the conveyors 17 ', 17 "which transfer the ballast excavated towards the distribution and leveling R.

L'unité R (figure 8) constituée essentiellement d'un système de répartition tel que le wagon trémie 28 dans lequel est déversé le ballast excavé par l'unité S et d'une bourreuse niveleuse 29, indépendante du reste de la rame de renouvellement.The R unit (Figure 8) consisting essentially a distribution system such as the hopper wagon 28 in which is discharged the ballast excavated by unit S and a tamper grader 29, independent of the rest of the train renewal.

A l'aide du matériel qui vient d'être décrit on procède selon l'invention de la manière suivante :Using the material which has just been described, proceeds according to the invention as follows:

Au fur et à mesure de l'avancement du train de substitution, les rails usés sont écartés sur le côté de la voie tandis que les traverses usées sont enlevées et stockées sur les wagons prévus à cet effet de l'unité T, on enlève partiellement le ballast à l'aide de l'excavatrice sur une hauteur suffisante pour compenser les différences de hauteur entre le matériel ancien et le matériel nouveau, tout en laissant sur la plate-forme une assise de ballast constituant le lit de pose des traverses neuves (Fig.9c). Le ballast excavé est transporté tel quel et déversé dans le wagon trémie du poste R. Les traverses neuves sont déposées immédiatement derrière l'excavatrice, et les rails neufs sont ramenés sur les traverses puis fixés à l'aide des moyens portés par la rame V (Fig.9d). Le ballast excavé est alors redistribué sur la voie neuve (Fig.9e) et réparti et nivelé par l'action de la bourreuse 29 (Fig.9f).As the train progresses substitution, the worn rails are moved aside on the side of the track while the worn sleepers are removed and stored on the wagons provided for this purpose in unit T, we partially removes ballast using excavator sufficient height to compensate for differences of height between the old material and the new material, while leaving a ballast seat on the platform constituting the bed for laying new sleepers (Fig. 9c). The excavated ballast is transported as is and dumped in the hopper wagon of station R. The new sleepers are immediately behind the excavator, and the rails new ones are brought back to the sleepers and then fixed using means carried by the V train (Fig. 9d). The excavated ballast is then redistributed on the new track (Fig. 9e) and distributed and leveled by the action of tamping machine 29 (Fig.9f).

Ainsi le matériel est posé sur une assise compactée et le réemploi immédiat du ballast excavé assure en combinaison avec le travail de la bourreuse une stabilisation suffisante de la voie pour permettre à titre provisoire une circulation commerciale d'environ 120 km/h pendant les périodes de reddition de la voie.So the material is placed on a compacted base and immediate reuse of the excavated ballast ensures combination with the work of the tamping machine a sufficient stabilization of the track to allow provisional commercial traffic of around 120 km / h during the surrender periods.

Le remplacement complet du ballast et sa stabilisation définitive est assuré lors d'un poste supplémentaire de travail à l'aide de matériel classique travaillant en temps masqué sur la longueur du chantier de renouvellement.Complete replacement of the ballast and its final stabilization is ensured during a shift additional work using conventional equipment working in masked time along the length of the construction site renewal.

Outre l'avantage de procurer une voie provisoire renouvelée capable de supporter une vitesse commerciale de l'ordre de 120 km/h lors des périodes de reddition, le procédé selon l'invention permet de traiter les chantiers de renouvellement partiels dans lesquels seul le matériel de voie est à remplacer sans affecter le profil longitudinal initial de la ligne, condition indispensable pour les raccordements sur points fixes (aiguillage zone de quai, ouvrage d'art), le renouvellement du ballast étant effectué lors d'une opération préalable ou ultérieure.Besides the advantage of providing a temporary route renewed capable of supporting a commercial speed of around 120 km / h during surrender periods, the process according to the invention makes it possible to treat construction sites partial renewal in which only the material is to be replaced without affecting the profile initial longitudinal line, essential condition for connections on fixed points (point switch quay, structure), the renewal of the ballast being carried out during a prior or subsequent operation.
