The Tianjin Metro or Tianjin Rail Transit is the rapid transit system in the city of Tianjin,which was the second city in mainland China after Beijing to operate a subway system (the Beijing Subway opened in 1971). First opened in 1984,the system currently has 8 operating lines and 205 stations spanning 296.6 km (184.3 mi).
The lines are jointly operated by two companies:the Tianjin Metro Group Co. Ltd and the Binhai Mass Transit Development Co. Ltd. The former operates Lines 1,2,3,6,and 10,while the latter operates Lines 5 and 9. The two companies merged and regrouped as the Tianjin Rail Transit Group Co. (TRT) in 2017,unifying the operations.
Tianjin,as an inland harbor of China,has long been a major commercial city. After the founding of the People's Republic in 1949,the number of vehicles on the roads significantly increased,causing pollution. To overcome these problems,the transport authority decided to close the old tram network and switch over to a rapid transit system.
However,due to cost,it was not until 1970 that construction of the system first took place. The first section,spanning 3.6 km (2.2 mi) of track and 4 stations (Xinhualu,Yingkoudao,Anshandao and Haiguangsi),was completed by February 1976. Further construction was delayed due to an earthquake in 1976.  The second section,with an additional 1.6 km (0.99 mi) of track and the Xinanjiao and Erweilu stations,was completed by 1980. After construction resumed,the total length was 7.4 km (4.6 mi),with 8 stations,  and service on the line began on 28 December 1984.
To reduce construction costs,the transport authority decided to use an abandoned canal bed to form part of the system,and did not dig deeply. By using the canal bed,the underground section is only 2–3 meters (6 ft 7 in –9 ft 10 in) under the street surface,and was the world's shallowest metro. There were only 1,000 full-time construction workers at that time;the others were volunteers from factories,schools and institutions all over the city. The average number of volunteer workers exceeded 2,000 a day,which rendered the project unique in the world then. Construction was delayed in 1976 when an earthquake hit the city,but was resumed in 1979 and completed by 1984.
At the end of the 1990s,it was observed that the Metro system was quite out of date. The atmosphere of the stations was uninviting,difficult to navigate,and with few passenger amenities on the platforms. Trains were infrequent,sporadic,and commonly delayed. The trains themselves were dilapidated,seat covers often torn off,and dim. Taking into consideration more modern,cleaner systems in East Asia,a massive reconstruction,modernization and expansion plan was laid out in 2000. In preparation,the system was closed on 1 September 2001,with renovation starting on 21 November of the same year. After purchasing new rolling stock,adding half-height platform screen doors and extending the line up to Shuanglin,the line re-opened on 6 December 2006 as Line 1,after trial testing that began on 12 June of that year.
During the renovation of the first line,other lines underwent construction. Line 9,operated by Binhai Mass Transit Development Co. Ltd,began construction in 2001  and its first section opened on 28 March 2004. Between 2004 and 2007,many new stations on the line opened successively. On 1 May 2011,the line was further extended westwards by 3 stations,bringing it to its current length of 52.8 km (32.8 mi). The Tram line in the system,the TEDA Modern Guided Rail Tram,was built to serve the Tianjin Economic Development Area and was opened on 10 May 2007. Line 2,after a lengthy construction delay and a structural accident,finally opened,as two separate sections,to the public on 1 July 2012,with the sections being reconnected on 28 August 2013. Line 3,another main north-south line,opened in October 2012.
