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.
