Nanjing Metro System

**Nanjing Metro System** is the system of the current 12 metro lines, 7 lines under construction and 10 lines under planning. The lines in operation have a total length of apporximately 460km. Planning started in the 1980s, and the first line, Line 1, was completed in 2005.

Currently, about 2.5 to 3 million passengers take Nanjing Metro daily, and about 0.8 million of them take Line 1, making it one of the busiest lines in the system. Only less than 10 thousand of them take line S7, making it one of the lines with the least passengers, along with line S9(usually less than 15 thousand).

## Lines

**This list only contains lines that are finished and in operation now.**

## Passangers

**Data collected from Nanjing metro's official website, and the current table is based on the information between Sept 29 2022 and Mar 4 2023.**

## Miscellanous

Nanjing South Railway Station has 4 lines passing through it currently, which is the most in Nanjing. It will also hold this record when all lines planned are finished.

Xinjiekou(City Center) has 24 exits, but they're not simply named 1-24. There are TWO exit 5 and 6s, and there are no exit 17 or 18, exit 19 is not opened now, and exit 23 has closed. Other exits from 1-24 are normal.

Currently, the shortest metro line is Metro Line 7(If counting only the northern or southern section), and the longest is Metro Line S9(but it is the shortest by carriage length & full train length).

Metro Line 7 is the only line that is operated with unmanned trains and is operated in two seperate sections currently.
