The approximate equivalence is shown as follows. In BS 11, rail sections are identified by a number which is the approximat

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

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
