plate-forme ferroviaire

chemin de fer
I am desperately looking for the correct translation of "plate-forme ferroviaire". This does NOT mean a train platform where passengers wait, but the platform on which the tracks are laid.
Contexte: "Largeur utile de la plate-forme ferroviaire: Les deux voies de la ligne nouvelle sont écartées de 4,50 m.
Sur ouvrage d’art, une piste de 0,75 m est prévue de chaque côté des voies, à 3,05 m au moins de l’axe de la voie la plus proche. La largeur minimale de la plate-forme ferroviaire entre lisses des mains courantes de sécurité est alors égale à 12,30 m."
Thanks!

track formation
For BSI, "Prepared surface of ground on which track is laid".
Cf (from Kiwipedia):
Arase terrassement Formation level (bottom of bulk excavations); cut depth (roads)
Infrastructure (of roads, railways) Earthworks, formation, pavement, etc.
Plate-forme Formation [Scott]
formation (grade USA) The surface of the ground in its final shape after completion of earthworrk, but before concreting. [Scott Civ. Eng.]
formation level (final grade, grade level USA) The surface level (or elevation) of the ground surface after all digging and filling but before concreting. [Scott Civ. Eng.]
formation The surface of a completed excavation, usually a level bottom, ready for the following work, after bottoming or trimming ... [Scott Bldg.]
Note that railways and roads are not just plonked on the ground as a rule, but are plonked on prepared ground which involves cutting out a certain depth of topsoil before placement of gravel, cement, etc. compacting, etc., so there is a certain amount of excavation, though hardly deep.
Note that "track bedding" refers to ballast and that a/c to my notes at least "track bed is the top surface of ballast" : BSI again - "track bed Surface of ballast on which sleepers are laid".
PLATE-FORME ... Surface préparée pour réaliser une route, une voie ferrée [DICO TP, which goes on to explain that for roads (plate-forme support), it consists of the supporting ground, whether cut or fill, the top 1 m of which is called the Partie Supérieure du Terrassement or PST, and une couche de forme éventuelle.

According to Network Rail, the "TRACKBED" is the layers of ballast and sub-ballast ABOVE a PREPARED SUBGRADE/FORMATION (see diagram). It is designed primarily to reduce the stress on the subgrade.
OTHER DEFINITIONS include the SURFACE OF THE BALLAST ON WHICH THE TRACK IS LAID,[1] the area left after a track has been dismantled and the ballast removed[1] OR THE TRACK FORMATION BENEATH THE BALLAST AND ABOVE THE NATURAL GROUND.[2]
en.wikipedia.org/wiki/Track_bed
All the above refers to situations where the track is laid on the ground. For your bridge, I hardly think "formation" is fully appropriate, but then again plate-forme probably isn't either. You might be looking at something like "track deck" here.

subgrade (track formation)
palte-forme [palie] de la voie = Erdplanum, Bahnkörper = [track] formation, subgrad (Am)
(UIC, Lexique général des termes ferrovaires)
Below the ballast is a subgrade (formation) which may be the surface of the natural ground, or may have some geotechnical system installed to improve ground stability and drainage. The subgrade may loosely be considered to be part of the "track" but the subgrade with the track itself is more properly said to form the infrastructure.

The majority of railway track still reflects its original construction some 150 years ago. Figure 1 shows a typical cross section of railway track in which the ballast layer has been placed directly onto a subgrade that has received little or no treatment other than shaping to the approximate line and level required. The stiffness of the subgrade is variable and deteriorates due to the ingress of water through the open textured ballast and from the dynamic loading of railway vehicles.
