La présente invention concerne un système de voie, qui est destiné à une ligne de transport de passagers à suspension magnétique, et qui comprend une structure principale de poutres porteuses constituée en l'espèce, d'un support en poutre-caisson (10) servant de corps porteur principal; de supports de voie (20) posés sur le support en poutre-caisson (10); et de poutres porteuses (30) posées sur les supports de voie (20) et utilisées pour supporter et guider un train à suspension magnétique. Les supports de voie (20) sont coulés de façon à s'intégrer au support en poutre-caisson (10) et servent de structure de voie de base de façon à supporter conjointement le train à suspension magnétique. Les poutres porteuses (30) sont constituées, d'une part de poutres porteuses en plaques (31) posées sur le support de voie (20), et d'autre part de poutres porteuses en π (32) posées entre sur les supports de voie sur des piliers (40). En outre, les structures de communication au sol avec les trains (50) peuvent être installées des deux côtés de la surface supérieure du support en poutre-caisson (10), et des structures d'évacuation sécurisées (60) peuvent être installées dans l'emprise de la voie.
