# Line 1 (Tianjin Metro)

Line 1 of the Tianjin Metro (Chinese: 天津地铁一号线; pinyin: Tiānjīn Dìtiě Yī Hào Xiàn) runs from the north-west to the south-east of downtown Tianjin. It is 42.227 km (26.2 mi) in length with 32 stations (currently 27 stations in operation).
The line started operations on 12 June 2006. It was rebuilt from the original Tianjin Metro line, which opened in 1976, but had to close down and undergo renovations in 2001 as part of the system's modernizing project. The line's color is red.

## History

Construction began in 1970. The first section, spanning 3.6 km of track and 4 stations, which are named Xinhualu, Yingkoudao, Anshandao and Haiguangsi stations, was completed by February 1976. The second section, with an additional 1.6 km of track and the Xi'nanjiao and Erweilu stations, was completed by 1980. After construction resumed, the total length was 7.4 km, with 8 stations, and service on the line began on 28 December 1984.
To cut construction costs, the authority used an abandoned canal bed to build part of the system. Thus the underground section is only 2–3 meters beneath the street surface, and was the world's shallowest metro. Years later, train frequency reduced and trains were commonly delayed. The rolling stock had become dilapidated, with most seat covers torn off, and lights becoming dim. To change to a more modern and cleaner system, a modernization plan was laid out in 2000. In preparation, the system was closed on 1 September 2001, with renovation starting on 21 November after being delayed due to the terrorist attacks of 11 September. After introducing new rolling stock, adding half-height platform screen doors and extending the line to Shuanglin, the line was completed at the end of 2005 and re-opened on 12 June 2006.
In 2008, Xizhan station was temporarily closed for the reconstruction of Tianjin West railway station. It reopened on 1 July 2011.
In 2016, the at-grade Shuanglin station was closed. On 3 December 2018, Shuanglin station was reopened as a new underground station.
On 3 December 2018, Line 1 also extended by one station, from Shuanglin station to Lilou station.
On 28 December 2019, four stations on the eastern extension (Gaozhuangzi, Beiyangcun, Guozhanlu, Donggulu) were opened.
On 12 May 2021, Beiyangcun station was renamed to Guojiahuizhanzhongxin station, and Guozhanlu station was renamed to Guoruilu station.
Hongnihedong station opened on 31 July 2023.
A two-station extension from Donggulu station to the new terminus at Shuangqiaohe station, with a not yet opened station at Xianshuigubei, opened on 1 July 2024.
The signal system was also replaced by the new ATO system, and the running stock was also overhauled.

### Alignment and interchanges

All elevated stations are entirely covered by a mixture of transparent & opaque corrugated sheets. The line passes through six districts, namely Beichen, Hongqiao, Nankai, Heping, Hexi and Jinnan. The whole journey takes about 50 minutes. The line is interchange with other metro lines: Lines 2, 3, 5 and 6. And interchanges to future lines will be available with Lines 4, 7, 8 and 10.

### Concourse Level

All line 1 station concourses are equipped with a customer service center, ticket vending machines, automatic fare gates, and bank ATMs.

### Platform level

For security and other reasons, all line 1 stations have platform-edge doors installed. TVs are installed that display travel tips, advertising, alerts, and waiting time for the next train.
