Abstract

Wagon de marchandises, de type porte-automobiles, conçu pour le transport de chargements relativement fragiles de faible densité et de valeur relativement élevée. Le wagon est pourvu de bogies qui possèdent plusieurs amortisseurs disposés dans quatre coins du cadre latéral. Les groupes de ressorts, dans les cadres latéraux, sont relativement souples et offrent une faible fréquence d'oscillation verticale naturelle. Dans un mode de réalisation articulé, un ballast placé de manière différentielle est fixé pour de façon à être sollicité pour charger les wagons d'extrémités du coupleur afin d'encourager une réponse dynamique similaire à la réponse dynamique des wagons internes.
