 The tramway system which grew in complexity up to 1906 is barely visible.The last part to be built, leading from Bent Street to the east end of the Sercombe kiln, was visible as a drainage channel until the new Coalex offices and laboratory were built across it in 1981.The north end of this earlier tramway from Bent Street running south parallel to the original Hassan Street is now under Silcock Street and the tramway connecting the colliery with the clay-products section has been largely removed by works associated with the supermarket on the colliery site.
