After the closure of Eldon sidings all clay exports were via lorry. For several years the clay was carried from the mines across the A351 by trains to the "Lorry Drop". It was realised that the lorries could take the clay directly from the mines and the cost of maintaining a railway system avoided. The transhipment buildings were raised to accommodate the lorries beneath them and in the early 1970s the railway system sold partly into preservation and the rest scrapped. Use of narrow gauge railways continued underground at Norden No 6 & 7 mines until all mining operations ceased in 1999.

Load Brook was developed from a farm to a minor industrial site in the late 19th and early 20th centuries. A "pot clay" mine (pot clay – a type of fireclay from the Stannington pot clay bed) was developed to the southwest in the 1850s by William Trickett, a local farmer. Trickett obtained rights to mine pot clay from the landowner, the Duke of Norfolk in 1852 and was mentioned in the Sheffield Trade Directory of 1862 as a clay merchant. William Trickett died in 1890 and the business was continued by his three sons, William, Benjamin and Matthew under the name of B. Trickett & Co.
