The British Railways, excluding the London Transport lines, has adopted as standard the flat-bottom rail instead of the traditional bull-head type. Diagrams are given of 113-lb, 109-lb, and 98-lb flat-bottom rails. The 109-lb rail will be used on main-lines and others carrying intensive traffic at high speeds. It will replace the 95-lb bull-head rails. The 98-lb flat bottom rail supersedes the 85-lb bull-head rail for secondary lines. The new rails will be much stronger both vertically and laterally than the bull-head types they are replacing and will keep better alignment. Comparisons of the properties of the 109 lb and 98-lb flat-bottom, rails are made with the bull-head rails they will replace.
