By 1857 a small ironworks was established called Heyford Ironworks. It was on east of the West Coast Main Line on a piece of land bounded by the railway, the road to Upper Stowe (Furnace Lane) and the canal. It used ore from the Blisworth area mostly, but also for a short time local ore from a quarry on the other side of the railway, a little to the south at Heyford Hills. The ore was possibly transported to the works by horse and cart or by an inclined tramway up to the railway where it would have been tipped into railway wagons for the very short trip to the works. The quarry was in operation from 1863 to 1868. The works closed in the early 1890s.
