Before concluding this letter, it is a duty which I have much pleasure in performing to acknowledge the great assistance which has been afforded to me by George Stephenson, Esq., the Engineer of the Liverpool and Manchester Railway,* in introducing malleable iron Railway bars.
The Stockton and Darlington Railway Company were the first public company who adopted the use of malleable Iron Railway bars,* and this they did after a deliberate examination of the arguments which were urged both in their favour and against them; and with the advice of Mr Stephenson, who was then their Engineer, and who, although interested in favour of cast iron, (being a joint-patentee of the best cast-iron Railway bars then in use,) yet had the candour to recommend the others as superior.*
Believe me, my dear Sir,
Very truly yours,
Michael Longridge.

* The railway, which was the world’s first intercity line, opened in 1830, five years after the S&D opened on September 27th, 1825. See posts tagged Liverpool and Manchester Railway.

* In his tale of the Stockton and Darlington Railway’s founding, local historian Michael Heavisides recorded Stephenson’s words: “Cast-iron rails will not stand the weight, there is no wear in them, and you will be at no end of expense for repairs and re-lays.” The sum lost by Stephenson as a result of this quixotic gesture was £500, roughly equivalent to £43,000 in 2021. It was not the only time he put into practice the railway’s motto, privatum periculum utilitas publica (private risk, public benefit): see also The Geordie Lamp.
