Mr.Tylor states that he was informed by the son of Richard Reynolds that the wrought iron made at Coalbrookdale by the Cranege process "was very good, quite tough, and broke with a long, bright, fibrous fracture: that made by Cort afterwards was quite different." [8] Though Mr.Reynolds's generosity to the Craneges is apparent; in the course which he adopted in securing for them a patent for the invention in their own names, it does not appear to have proved of much advantage to them; and they failed to rise above the rank which they occupied when their valuable discovery was patented.

This, however, was no fault of Richard Reynolds, but was mainly attributable to the circumstance of other inventions in a great measure superseding their process, and depriving them of the benefits of their ingenuity.
Among the important improvements introduced by Mr.Reynolds while managing the Coalbrookdale Works, was the adoption by him for the first time of iron instead of wooden rails in the tram-roads along which coal and iron were conveyed from one part of the works to another, as well as to the loading-places along the river Severn.

He observed that the wooden rails soon became decayed, besides being liable to be broken by the heavy loads passing over them, occasioning much loss of time, interruption to business, and heavy expenses in repairs.

It occurred to him that these inconveniences would be obviated by the use of rails of cast-iron; and, having tried an experiment with them, it answered so well, that in 1767 the whole of the wooden rails were taken up and replaced by rails of iron.

Thus was the era of iron railroads fairly initiated at Coalbrookdale, and the example of Mr.Reynolds was shortly after followed on all the tramroads throughout the Country.
It is also worthy of note that the first iron bridge ever erected was cast and made at the Coalbrookdale Works--its projection as well as its erection being mainly due to the skill and enterprise of Abraham Darby the third.
