摘要： A switch includes a frame constituted, inter alia, by a single point end plate, preferably mechanically welded, for supporting stock rails at ends thereof adjacent a principle route, and by a double heel end plate, preferably mechanically welded, for supporting heel ends of each of two stock rail/switchblade pairs adjacent a direct route and a deviated route. Spacers maintain distance between the stock rails adjacent the principal route and the stock rail/switchblade heel pairs adjacent the direct and deviated route. Sole plates support the stock rails and/or switchblades. Inner stops are placed between the switchblades in the vicinity of their heel ends and are carried by the sole plates. Outer stops are placed between the stock rails and the switchblades in the vicinity of their point ends and are carried by the stock rails.
