Tay Rail Bridge
The Norwood accident in 1891 led to a review of all similar structures by Sir John Fowler, who recommended their replacement. Cast iron had been used very successfully in the Crystal Palace of 1851 and the Crumlin Viaduct in South Wales (built in 1857), but the first Tay Rail Bridge of 1878 failed catastrophically due to its poor use of the material, putting the cast iron lugs on the columns into tension. The Tay Bridge disaster stimulated engineers to use steel, as exemplified by the Forth Bridge of 1890.
