Abstract

La présente invention concerne une barre de jauge transversale (4) qui maintient l'espacement entre deux supports (6a, 6b) de rail longitudinal (1, 21) opposés et parallèles. Un agencement de verrouillage (10) a un mécanisme de verrouillage (15) avec une partie (17) qui s'étend dans un évidement (16) dans le support respectif. Des verrous ou des bras se verrouillent dans des évidements de verrouillage respectifs (19) à l'intérieur du longeron lorsque des leviers (12, 14) sont actionnés. Une voie ferrée (100) est montée sur des rails (21) d'un système de voie ferrée existant. Un socle repose sur des traverses (40) d'un système de voie ferrée existant ou est supporté sur les rails de la voie ferrée existante. Un matériau élastique (38), tel que le PEHD, se trouve entre une plinthe (36) et le sommet de chaque rail (21) pour aider à réduire le transfert de vibrations vers le système de rail existant. Une voie ferrée élevée (200) a une structure de support (204).
