Only 40 passengers used British Steel Redcar in North Yorkshire in 2017/18, according to Office of Rail and Road figures.
The coke ovens and blast furnace at the nearby SSI steel plant were shut down in 2015 - leading to a drop in demand for the railway station - but there are still some people employed at the site.
Just four Northern trains stop at the station each day between Monday and Saturday, two to Bishop Auckland and two to Saltburn. There are no trains on Sundays.
According to the National Rail Enquiries website, the station is also known as Redcar British Steel and has no ticket machines, no waiting room, no toilet facilities and no step-free access.
It is located near the town of Redcar, which recently featured in BBC documentary The Mighty Redcar.
Last year’s least used station - Barry Links in Angus, Scotland - saw the number of entries and exits more than double to 52, making it only the second least used station.
The other three railway stations in Britain with fewer than 100 entries and exits in the past year were Denton, Greater Manchester (70); Teesside Airport, County Durham (74); and Stanlow and Thornton, Cheshire (92).
Many stations are kept open despite being rarely used because it is easier to arrange for a train to stop infrequently than obtain permission to close a station.
Rail enthusiasts often visit the least used station from the previous year to boost its passenger numbers.
