New Penyvan Level.
In the late 1880’s the new Penyvan Level was established, it was on the same side of the mountain just south of the Graig Fawr Colliery near Llandafal Village, Cwm. The tramway from this new Penyvan Level came down into the Graig Fawr Colliery and was connected by a surface tramway to the old Penyvan Colliery towards the south (as seen on the map above).
By 1920 the Graig Fawr Colliery was disused, the tramway from the old Penyvan Colliery was also disused though the new Penyvan Level was still in operation.
