Steam dominated on narrow gauge railways in the UK until the steady introduction of petrol powered locomotives after their rapid development during the 1914-18 war. The last industrial system, at Bowaters Paper Mills in Sittingborne, finally dispensed with industrial use of their steam railway in 1970. Although rare, there are still a few operating narrow gauge industrial steam railways in other parts of the world.
