Kitty's Drift was an underground railway, built in 1770 to transport coal underground from East Kenton Colliery to the staithes at Scotswood. It was a single track wooden waggonway with passing places for horse drawn waggons. The tunnel was said to be 3 miles long, 6 feet high and 6 feet wide. The route was abandoned in 1805 and replaced by a surface waggonway, but the drift continued in use as a main drainage level for many years. The entrance was close to Montague Colliery, View Pit (HER 4059). The Mickley Coal Company therefore utilised part of Kitty's Drift in the 1930s to take coal from Caroline Pit (HER 4289) to the screens at the closed View Pit. Originally Kitty's Drift used a massive steam winder to haul the tubs the 2.5 miles to the View Pit screens, but in 1933 this was replaced by a 250 horsepower electric winder. The Mickley Coal Company intercepted Kitty's Drift with Bates Drift, at a gradient of 1 in 3 from the Beaumont seam. And the Fan Pit Level Drift, which was 980 yards long, carried tubs from the shaft up to Kitty's Drift and on to View Pit. This created a complex and extensive underground endless rope haulage system in places up to 6 miles in length. The Montague Colliery (and therefore Kitty's Drift) closed again in 1959. The exact route of the underground railway is not known - it is shown as a "Subterranean Tunnel on Lambert's map of 1807). Said to have been the westernmost end of the Coxlodge Wagonway (HER 1134). Possibly the earliest underground railway in the world.

Opened before 1710, closed March 1935. Little Pit was sunk in 1894. Victoria Pit was at NZ 317 543. Owned by Sir George Elliot, Bart, then Lambton Collieries Ltd, then Lambton and Hetton Collieries Ltd. On November 17 1771, North Biddick, Chartershaugh and Low Lambton Collieries filled with water. Over 30 horses drowned, the wagons were swept away and the fire engines destroyed. Whellan reported in 1894 that there were two upcast and three downcast shafts at this colliery. Daily output was 940 tons of coal. 600 workers on the Maudlin seam and 350 on the Hutton seam. An explosion on 28 January 1743 killed 17 miners. Another on 6 December 1773 killed 19.

Opened by Earl of Durham in 1874. There were two pits - No.1 and No. 2. Taken over by Lambton Collieries Ltd in 1896, then by Lambton and Hetton Collieries Ltd, then Lambton, Hetton and Joicey Collieries Ltd until 1947 when the National Coal Board took over. Whellan reports that in 1894, the daily output was 1000 tons of coal, and there were 800 employees. New Herrington was apparently a "populous" colliery village with a chapel of the Bible Christians and a Christian Lay Church. There was also a lecture hall to seat 450 people, Co-operative stores, billiard, recreation and reading rooms. The Earl of Durham erected St Cuthbert's National School for 700 children. In the twentieth century there was a shortage of grass to use for pony feed. The first experimental plant for making straw pulp to feed young ponies was set up at the pony farm of Herrington Colliery in August 1941. The plant pickled chopped straw in caustic soda to break up the woody skin, to create a pulp which could be fed to ponies instead of a portion of oats or hay. Later in 1941 an underground plant was set up at the pit to provide food for the ponies in fulltime work.

Opened in 1914 by John Bowes and Partners. Closed December 1932.
