Crossing points for railway tracks - have centre block diverging to counter-point rails with projections on sides fitting into web of rails

摘要

The points for railway track crossings have a rectilinear central block that diverges in the direction of the counterpoint rails. The central block (1) has track grooves (2, 3) for wagon wheels and is shaped to follow rails (4, 5) which dog leg left and right to the counterpoint rails (6, 7). The top lateral faces of the central block are housed in notches in the mushroom shaped top flange of the rails while the sides of the block have projections fitting into the web of the rails. The latter projections accommodate assembly bolt holes.
