Important changes in British Standard 11 for flat-bottom rails are given. These new rails, designated "A" series, have larger fillet radii, joining web to head; use equal top and bottom fishing angles resulting in the reversion to the double angle foot, to obviate an unbalanced section, with excess metal in the foot; have reduced foot widths to allow better disposition of metal within the section; have sides tapered 1 to 10 to give added metal to resist wear; and have a larger head radius.
