Source-derived summary

The Bannan line (Chinese: 板南線; also known as the Blue line) is a metro line of Taipei Metro in Taipei, Taiwan, with a total of 23 stations serving the districts of Nangang, Xinyi, Daan, Zhongshan, Wanhua, Banqiao and Tucheng. The line's name is a portmanteau of "Banqiao" and "Nangang".

The entire line runs underground. The excavation of tunnels using the cut-and-cover method resulted in large scale detouring of road traffic. Because of that, the line runs beneath existing roads and totals 28.3 km (17.6 mi).

Overview

Service on this line is divided into a full-length service from Taipei Nangang Exhibition Center to Dingpu, as well as a shorter service from Taipei Nangang Exhibition Center to Far Eastern Hospital.

Due to Taipei City Hall being at the centre of the Taipei 101 New Year's festivities, intervals between trains can be reduced to a minimum of 135 seconds, transporting up to 39,000 passengers per hour. This results in an average of about 27 trains per hour on the line during peak hours.

History

8 November 1990: The Nangang section begins construction.

30 December 1991: The Taipei Main Station western underground passageway opens.

Editorial analysis

Why this record matters

“Bannan line” is worth following because a concise public description often conceals a longer documentary argument. Here, Bannan, line and Metro provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q708378. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1990 and 1991.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
