Line 10, Beijing Subway

Line 10 of the Beijing Subway (Chinese: 北京地铁10号线; pinyin: běijīng dìtiě shíhào xiàn) is the second loop line in Beijing's rapid transit network as well as the longest and most widely used line. The line is 57.1 km in length and runs entirely underground through Haidian, Chaoyang and Fengtai Districts, either directly underneath or just beyond the 3rd Ring Road. The Line 10 loop is situated between two to six kilometers outside of the Line 2 loop, which circumnavigates Beijing's old city. Every subway line through the city centre intersects with Line 10, which has 24 (currently 14 available) transfer stations along route, and 45 stations in all. Line 10's color is      Capri.

Line 10 is the world's longest subway loop line and one of the longest entirely underground subway lines. It is also the longest line to use Siemens' Communication Based Train Control (CBTC) system.

History

Planning

The Beijing Subway network was originally conceived to have only one ring line. The booming economy and explosive population growth of Beijing has put a huge amount of demand on Line 2, surpassing its designed capacity. In 2001 and 2002, the China Academy of Urban Planning and Design proposed that two "L-shaped" lines named Line 10 and 11. Together they will form a second loop around Beijing and relieve traffic demand on line 2.

Line 10 (Madrid Metro)

Line 10 of the Madrid Metro is the product of two lines, the former line 8 from Fuencarral to Nuevos Ministerios and the former Suburbano (also known as Line S) from Alonso Martínez to Aluche, this section being named line 10 in the 1980s, and formerly operated by FEVE until the management of Line S was transferred to the Community of Madrid. In the 1990s, Madrid planned for these two lines to become one, but there was a problem. Line 8 was large profile and Line S was Small profile, so Madrid decided it was going to rebuild the Suburbano section to fit large profile rolling stock, a feat that took five years to complete. During this process, all island platforms were demolished, tunnels were widened, platforms cut back and stations modernised. Also a new section between Alonso Martinez and Nuevos Ministerios had to be built, with an intermediate station at Gregorio Marañón. Finally once this was all finished, the whole line could use large rolling stock and the line was extended from the New Casa de Campo to Colonia Jardín. The section between Casa de Campo and Aluche was handed over to line 5 which now terminates at Casa de Campo.
