Input (English): Context: Charing Cross (sometimes informally abbreviated as Charing X) is a London Underground station at Charing Cross in the City of Westminster with entrances located in Trafalgar Square and The Strand. The station is served by the Northern and Bakerloo lines and provides an interchange with the National Rail network at station. On the Northern line it is between and stations on the Charing Cross branch, and on the Bakerloo line it is between Embankment and stations. The station is in Travelcard Zone 1. The station was served by the Jubilee line between 1979 and 1999, acting as the southern terminus of the line during that period., The Jubilee line is a London Underground line. Opened in 1979, it is the newest line on the network, although some sections of track date back to 1932 and some stations to 1879. Its western end beyond Baker Street was previously the Stanmore branch of the Bakerloo line, while the new build was completed in two major sections: initially in 1979 to Charing Cross tube station in central London; then extended in 1999 with the Jubilee Line Extension to Stratford station in east London. The later stations are larger and have special safety features, both aspects being attempts to future-proof the line. Following the extension into east London, serving areas once poorly connected to the Underground, the line has seen a huge growth in passenger numbers and is currently the third busiest on the network, with over 213 million passengers per year.
