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 nowadays used on the Bakerloo line. Following the withdrawal of the British Rail Class 483 EMUs in 2021, these trains are the oldest EMUs in passenger service in Britain. A total of 63 seven-car trains were built in two separate batches.
