Line 2

Line 2 is the small circle of the Beijing Subway. It's Moscow counterpart is Line 5. Most line 2 stations are named after Gates such as Fuxing men. Line 2's colour is blue. Some parts of line 1 is reverted into line 2. The whole loop line stays within the Beijing core districts Xicheng and Dongcheng (Dongxicheng).

Trivia

 * This is the first loop line in all of mainland China and the third loop line in the world. The second loop line in the whole world is line 5 in the Moscow Metro (loop finised in 1954). The first loop line in the whole world is the Glasgow Subway. However, the circle line in the London Underground DOES NOT count as a circle line because of an extension from Edgware Road to Hammersmith in 2009.
 * This is the inner loop in the Beijing Subway. The outer loop is Line 10.
 * Line 2 remarks on the most stations that sound like swearing if pronounced in English. Fuck as in Fuxing Men and shit as in Dongsi Shitiao.
 * It is a shallow metro line as it's maximum depth is B2. This is also the case with Shanghai Metro Line 8.
