Line 2 (Tianjin Metro)
Railway line of Tianjin Metro
Line 2 of the Tianjin Metro (Chinese: 天津地铁二号线; pinyin: Tiānjīn Dìtiě Èr Hào Xiàn) is a rapid transit line running from west to east Tianjin. Opened on 1 July 2012, the line is 27.157 km long and has 20 stations. It is mostly underground; all stations, with the exception of surface-level station Caozhuang, are underground.
In May 2011, during construction, a section of tunnel west of Tianjin railway station was flooded with water from the Hai River and collapsed, trapping one of the TBMs. It was deemed too expensive to remove the trapped TBM, so a decision to abandon the TBM and dig a new tunnel around it was made. This delayed the original opening date from late 2011 to 2012. After the line opened for trial operations on 1 July 2012, it operated in two separate sections until the affected section finished reconstruction and Jianguodao Station opened on 28 August 2013, finally reconnecting the two sections.
This brief starts where responsible research should: with the source description of “Line 2 (Tianjin Metro)” as railway line of Tianjin Metro. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as railway line of Tianjin Metro. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 22, 2026. The linked authority identifier is Q6553104. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2012, 2011 and 2013.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
