context_page_description: Green Park is a London Underground station located on the north side of Green Park, with entrances on both sides of Piccadilly. It is served by the Jubilee, Piccadilly and Victoria lines. On the Jubilee line it is between Bond Street and Westminster; on the Piccadilly line it is between Piccadilly Circus and Hyde Park Corner and on the Victoria line it is between Victoria and Oxford Circus. It is in fare zone 1.
  The station was opened in 1906 by the Great Northern, Piccadilly and Brompton Railway and was originally named Dover Street due to its location in that street. It was modernised in the 1930s when lifts were replaced with escalators and extended in the 1960s and 1970s when the Victoria and Jubilee lines were constructed.
  The station is near The Ritz Hotel, the Royal Academy of Arts, St James's Palace, Berkeley Square, Bond Street, the Burlington Arcade and Fortnum & Mason, and is one of two serving Buckingham Palace.
context_section_description: The origins of the Jubilee line are less clearly defined than those of the Victoria line. During World War II and throughout the 1950s and early 1960s consideration was given to various routes connecting north-west and south-east London via the West End and the City of London. Planning of the Victoria line had the greater priority and it was not until after construction of that line started that detailed planning began for the new line, first called the Fleet line in 1965 as it was planned to run in an east-west direction along Fleet Street. Lack of funding meant that only the first stage of the proposed line, from Baker Street to Charing Cross, received royal assent in July 1969; funding was agreed in August 1971.
  Tunnelling began in February 1972 and was completed by the end of 1974. In 1977, during construction of the stations, the name of the line was changed to the Jubilee line, to mark the Queen's Silver Jubilee that year. A construction shaft in Hays Mews north of the station was used for an electrical substation and ventilation shaft. At Green Park, the ticket hall was enlarged slightly to provide space for escalators for the new line which connect to an intermediate concourse providing interchange between the Jubilee and Victoria lines. A second flight of escalators descends to the Jubilee line platforms, which are 31.1 metres (102 ft) below street level, the deepest of the three sets. Interchange between the Jubilee and Piccadilly lines was via the ticket hall. Platform walls were tiled in a deep red with black leaf patterns by June Fraser. Trial running of trains began in August 1978 and the Jubilee line opened on 1 May the next year. The line had been officially opened by Prince Charles the previous day, starting with a train journey from Green Park to Charing Cross. In 1993, to alleviate congestion, a third escalator was installed in the lower flight to replace a fixed staircase.
  Work on the Fleet line's stages 2 and 3 did not proceed and it was not until 1992 that an alternative route was approved. The Jubilee line extension took the line south of the River Thames via Waterloo, which was impractical to reach from the line's existing terminus at Charing Cross. New tunnels branching from the original route south of Green Park were to be constructed, and the line to Charing Cross was to be closed. Tunnelling began in May 1994, and improvements were carried out at Green Park to provide a direct passageway connection between the Jubilee and Piccadilly lines, including lifts to the  platforms at each end. A new ventilation shaft and an emergency exit to Arlington Street were built. The new extension opened in stages starting at Stratford in the east, with services to Charing Cross ending on 19 November 1999 and the final section between Green Park and Waterloo opening the following day.
