Taipei Metro is a metro system in Taipei and New Taipei, Taiwan. It consists of 131 stations (119 stations if transfer stations are counted once,) with 6 main routes and 2 branch lines, operating on 152.9 kilometres (95 mi) of revenue track. The Taipei Metro was the first metro system in Taiwan. The Taoyuan Metro's Airport Express link opened in March 2017 mainly to connect the Taipei Taoyuan Airport and the main station.
The system operates according to a spoke-hub distribution paradigm, with most rail lines running radially outward from central Taipei. The MRT system operates from 6 am to midnight daily (the last trains finish their runs by 1 am), with extended services during special events (such as New Year festivities). Trains operate at intervals of 1.5 to 15 minutes depending on the line and time of day. Smoking is forbidden in the entire metro system, while eating or drinking is prohibited in the area.
Stations become extremely crowded during rush hours, especially at transfer stations such as Taipei Main Station, Zhongxiao Fuxing, and Minquan West Road. Automated station announcements are recorded in Mandarin Chinese, English, Taiwanese, and Hakka.
