In late 1830's England, railway lines were of a vast range of different patterns. One of the earliest lines to use double-headed rail was the London and Birmingham Railway, which had offered a prize for the best design. If it was true that the rail could be turned over when the running surface became worn, the argument lost its validity as it evolved into the bullhead rail, with a heavier profile to the top edge. The lower edge also wore in patches where it was borne on the chairs. Although it became the standard on the British railway system until the mid-twentieth century, there seems to be nothing in the literature about any other advantages it may have had.

Flat bottomed rail was first introduced in America by R.L.Stevens in 1830. There were no steel mills in America capable of rolling long lengths, so it was manufactured in Britain. Charles Vignoles had observed the wear that was occurring with steel rails and steel chairs upon stone blocks, the normal system at that time. He may well have come across Stevens' idea and in 1836 recommended it to the London and Croydon Railway for which he was consulting engineer. ...

His rail had relatively speaking a much smaller cross-section, with a wider base than modern rail, fastened with screws through the base. Other lines which adopted it were the Hull and Selby, the Newcastle and North Shields, and the Mancester and Bolton. Once it became possible to preserve wooden sleepers with mercuric chloride, a process called "Kyanising", and creosote, they gave a much quiter ride and it was possible to fasten the rails directly using clips. Their use spread world-wide and aquired Vignoles' name. Mercury chloride is a white poisonous soluble crystalline sublimate of mercury, used as a pesticide or antiseptic or wood preservative. ...
