Les rails transversaux 12 sont également destinés à être agencés chacun sous un essieu 18 du véhicule ferroviaire 7.The transverse rails 12 are also intended to be each arranged under an axle 18 of the rail vehicle 7.

Chaque rail transversal 12 s'étend principalement suivant une première direction longitudinale L1 et présente une longueur suivant cette première direction longitudinale L1 et une largeur suivant une première direction transversale T1 perpendiculaire à la première direction longitudinale L1.Each transverse rail 12 extends mainly along a first longitudinal direction L1 and has a length along this first longitudinal direction L1 and a width along a first transverse direction T1 perpendicular to the first longitudinal direction L1.

Les voies transversales formées par une paire de rails transversaux 12 ont chacune une largeur qui dépend de la largeur des chariots 14.The transverse tracks formed by a pair of transverse rails 12 each have a width which depends on the width of the carriages 14.

Par exemple, les voies transversales ont une largeur comprise entre 800 mm et 1000 mm, en particulier entre 850 mm et 900 mm, typiquement égale à 897 mm.For example, the transverse tracks have a width of between 800 mm and 1000 mm, in particular between 850 mm and 900 mm, typically equal to 897 mm.

Par exemple, les rails transversaux 12 sont réalisés en métal, en particulier en acier.For example, the transverse rails 12 are made of metal, in particular of steel.

Chaque chariot 14 est adapté pour recevoir un essieu 18 du véhicule ferroviaire 7.Each carriage 14 is adapted to receive an axle 18 of the rail vehicle 7.

Chaque chariot 14 comprend un châssis 24 et des roues 25.Each trolley 14 comprises a frame 24 and wheels 25.
