A modular railway diamond crossing incorporates sets of acute and obtuse angle castings. The rail connections to the castings have a fine taper to minimize joint impacts. The castings are spaced apart with a combination of rails and cast blocks. The outside block is a tapered design that maintains the flangeway and holds the castings and rails together. The inside block comprises a tapered common center casting. This unit also maintains the flangeway and a longitudinal distance between the castings. The center casting is a common part to all such crossings regardless of the crossing angle.

Un croisement modulaire oblique de voies ferrées comprend des ensembles de pièces coulées à angles aigus et obtus. Les raccords des rails et des pièces coulées sont légèrement effilés afin de réduire le plus possible les impacts aux joints. Les pièces coulées sont espacées à l'aide de rails et de cales en fonte. La cale extérieure est effilée pour maintenir l'ornière et retenir ensemble les rails et les pièces coulées. La cale intérieure comporte une pièce coulée centrale affilée. Ce dispositif maintient aussi l'ornière ainsi qu'un espacement longitudinal entre les pièces coulées. La pièce coulée centrale est un élément commun à tous les croisements de ce genre, peu importe l'angle de croisement.
