 This is what we now call the Valley Floor Tramway - the Treffry era railways, all horse-worked, were later called tramways to distinguish them from later locomotive-powered lines.The quarries were worked until about 1928; the last stone came from Carbeans in 1933 and the last of Treffry's rails were removed in 1940.In 1872 a group of London businessmen began a massive rebuild of Treffry's tramways to enable them to exploit the ironstone deposits near Newquay.
