Guojia Tushuguan (National Library) Station, also known as National Library station or Guojiɑ Tushuguɑn Zhɑn) is an interchange station on Line 4, Line 9 and Line 16 of the Beijing Subway. Its name is derived from the nearby National Library of China. The station features a double-island interchange layout, with Line 4 trains on the outside and Line 9 trains on the inside, which allows most riders to change lines simply by crossing the platform, instead of walking between levels. This configuration is known as cross-platform interchange.^[2] The station handles 106,000 transfers between Lines 4 and 9 per day.^[3] The platform for Line 16 is built under the Line 4 and Line 9 platform.^[4] If the through service of Fangshan line to Line 9 is counted, which started on January 18, 2023, this would be the first four-line interchange on the Beijing Subway.
