Abstract: A railway frog has a pair of wing rails with converging and diverging portions. A point member is located between forward portions of the wing rails. The forward portion of at least one of the rails has a section adjacent the point that has the rail head removed. A replaceable wear component having a head is located on an upper surface of the web of the wing rail. The wear component has a skirt that bolts to the flange of the wing rail. The wear component is formed of manganese steel.

Abstract: A railbound manganese frog assembly having ramps and grooves adapted to receive the false flange formed on the rim of a worn railroad car wheel to prevent the flange from impacting components of the frog assembly.

Abstract: According to the invention a railway turnout comprises two wing rails and a point, carried on a frog, which includes a nose, the running surface of which is substantially co-planar with the running surfaces of the rail of the turnout, the wing rails being provided with tread surface inserts inclined upwardly above the plane of the running surfaces, the incline of the wing rails extending longitudinally along the wing rails towards the heels thereof and commencing at a point corresponding to the point of deviation from the gauge line, of the wing rail, the tread surface of the wing rails being shaped, in cross section, from the edge adjacent the gauge line, at an angle corresponding to the shape of the average worn car wheel and the angles of the incline and the slope being dependent on the taper on the wheels and on the angle of deflection of the turnout.
