The London Underground 1986 Tube Stock consisted of three prototype electric multiple units built for the London Underground from 1985 to 1986 that led to the development of the 1992 Stock.

History

In 1984, London Transport ordered three different prototype trains to test new materials, construction methods and seating layouts.[1] Two were built by Metro-Cammell at its Washwood Heath factory, and the third by British Rail Engineering Limited at its Derby Litchurch Lane Works.[2][3]

Each train consisted of 2 Coaches, and All were built to the same design and were able to operate together or be able to be coupled to a 1983 stock, despite each set having different electrical equipment supplied by different manufacturers. The first was delivered in October 1986.[4] To make their identification easier the prototypes were distinctively and individually coloured - red, blue and green.[2][5]

After a Public Display at Woodford Station in 1987, they usually operated in passenger service on the Jubilee line for most of their service life, with them also running on the Piccadilly Lines Aldwych Shuttle Until it closed in 1994, they also Operated on the Central Line on Very Rare Occasions, the Prototypes Were taken Out of service sometime around 1996 and Red & Blue Were Scrapped Shortly after, But Green was preserved at the London Transport Museum's Acton depot, but there were plans to relocate it to the Electric Railway Museum in 2016, but was cancelled after the Electric Railway Museum Closed

The public consultation results show that the green prototype was the winner, and provided the core design basis for the 1992 Stock that was built for London Underground's Central line.
