These were served by a network of metre gauge tramways which were moved as the working faces progressed.
They connected to the northern terminus of the Great Northern Railway's Eaton Branch Railway, which tipplers allowed unloading of the narrow gauge ore wagons into standard gauge trucks.
This was followed by a steady decline in the years after the war, as cheap imported steel entered the British market.
In 1949 further new sources of ironstone were needed and land was leased on the edge of the Belvoir Castle estate.
The line was lifted in 1959, with just a few sidings by the locomotive sheds at the southern end of the tramway left.
