 The second, the steel works section, and largest of all, was always self-contained and from its authorisation on 20 October 1864 lasted under locomotive haulage until the closure of steel production in 1932, but also in one short and occasionally used hand propelled section in the iron foundry until c1960.The third, the deviation works section (latterly devoted entirely to the joinery department), was an extensive system built on at least three levels and was an entirely separate, hand propelled, tramway, which survived in spasmodic use until about 1980.Several relics including examples of trackwork and three wagons survive from this installation.
