The London Underground 1972 Stock is a type of rolling stock used on the London Underground. The 1972 Stock was originally ordered to make up the shortfall in trains on the Northern line's 1959 Tube Stock fleet, but is currently used on the Bakerloo line. Following the withdrawal of the 1938 Stock-based British Rail Class 483 EMUs from the Isle of Wight in 2021, the 1972 Stock are now the oldest trains in regular passenger service in the United Kingdom. A total of 63 seven-car trains were built in two separate batches.
