47291 passes Upton Scudamore on 16 August 1984 with the 6V37 13:10 Furzebrook to Llandarcy oil tanks. This train conveyed crude oil from the Wytch Farm oil field, which is by far the largest of the UK's very few onshore oil wells. Production had only just started when this picture was taken, with less than 5,000 barrels a day being extracted. This reached a peak of 100,000 barrels a day in 1996, but the trains to Llandarcy ceased in 1987.
