发明名称 RAILWAY DIAMOND CROSSING
摘要 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.
