used on the network and classified as British Rail Class 484. The last converted 1938 stock ran in early 2021. Of the six units extant on the Isle of Wight at the time of retirement, four have been secured for preservation. 483006 and 483008 were obtained by the London Transport Traction Group for preservation on the Epping Ongar Railway. Two of the four preserved units are remaining on the Isle of Wight; 483007 was transferred to the adjacent Isle of Wight Steam Railway, initially as a static exhibit but with a medium-term goal of running the train, either via propulsion from one of the railway's diesel shunters or through the installation of a battery power supply system, while 483004, which had previously been used as a source of spare parts after withdrawal, was purchased by and delivered to Holliers Farm in Hale Common, near the village of Arreton. Accidents A crash involving 1938 stock occurred at Moorgate on 28 February 1975. A train hit the dead end wall of the station, killing 43 people including the driver in unclear circumstances. After the accident, a safety system named after the crash (Moorgate Protection) was introduced in 1978. Preservation In addition, some other units survive in preservation, including cars from the first-built unit, which are preserved at the London Transport Museum Depot in Acton. The preserved sets have been restored into their original red liveries, one with an orange roof (Bakerloo line) and one with a grey roof (other lines). The LTM operates trips of its preserved four-car set for railtours around the LU system. The 1938 stock is also used for occasional filming work.

Another unit, 483-007, known as "Jess Harper," was acquired by the Isle of Wight Steam Railway for static display. Media The Chronicles of Narnia: Prince Caspian (2008).
