(a) Where stub switches are used, the open space between the ends of the fixed and throw rails shall at no time be allowed to exceed 2 1/2 inches. Stub switches shall be equipped with head chairs which will insure a fixed spacing between the main and turnout rails.

(b) The crotch or wedge-shaped opening formed between switch point and stock rail shall be so filled as to eliminate the danger of a foot being jammed therein, where such openings occur in a walkway or roadway crossing tracks.

(c) The heel and toe crotch and the openings formed by wing rails shall be so filled as to eliminate the danger of a foot being jammed therein, where such openings occur in a walkway or roadway crossing tracks.

(d) The wedge-shaped openings at the ends of all guard rails, whether for frogs, curves or crossings, shall be so filled as to eliminate danger of a foot being jammed therein, where such an opening occurs in a walkway or roadway crossing tracks.

(e) Where the adjacent yard surface is approximately level with the head or top of the rail, any opening between the sides of the rail head and the adjacent pavement or other yard surface, which will permit a foot being jammed therein, shall be filled in or otherwise guarded where such openings occur in a walkway crossing tracks.
