It partially supersedes BS 11:1985 which will be amended accordingly. BS EN 13674-1:2003 applies to all new installations of Vignole (flat bottom) rail se

BS 11:1985 will be declared obsolescent following the publication of the other parts of BS EN 13674. This will be do

6、ttee can be obtained on request to its secretary. Additional information In this standard rail grades are based on hardness whereas in BS 11 they are based on tensile strength. The approximate equivalence is shown as follows. In BS 11, rail sections are identified by a number which is the approximat
7、e mass per a unit length of rails in lb/yd. An approximate conversion to kg/m can be made by multiplying the value in lb/yd by 0,49. NOTE The term “Vignole rail” is in common use elsewhere in Europe. It is derived from the name of Charles Blacker Vignoles, an early railway engineer who promoted the
8、use of flat bottom rail. The textual error set out below was discovered when the English language version of EN 13674-1 was adopted as the national standard. It has been reported to CEN/TC 256/SC 1 in a proposal to amend the text of the European standard. Table 5a) column headed “running surface” to
