Шанхай метросының 5-ші желісі

Metro line in Shanghai, China

Line 5 is a north–south rapid transit line of the Shanghai Metro network, running from station in Minhang District in the north to in Fengxian District was originally planned as the Minhang and Fengxian sections of line 1 extending south to Minhang. Despite its numeric designation, it was the fourth Shanghai Metro line to enter passenger service, opening on 25 November 2003. The line is colored violet on system maps.

Line 5 was originally built under the direction of Minhang District and remains the only line in Shanghai Metro system that was originally built under the supervision of a county level government. In 1998, Minhang District authorities signed a contract with Shanghai Jiushi Group to build the line. In 2000, Shanghai Jiushi Group signed a contract between Alstom to purchase trains In 2002, Shanghai Modern Rail Transit Incorporated, a subsidiary of former 上海久事公共交通集团有限公司, was given management of the line. The line entered passenger operations on 25 November 2003, on an initial segment between and stations, entirely within Minhang District. Prior to integration with the rest of the Shanghai Metro network, it used its own ticketing system. In 2005, it was integrated with Shanghai Metro's ticketing system, which enabled an in station interchange to line 1 at Xinzhuang station. At the same time, management and operation of the line was taken over by Shanghai No. 1 Metro Operation Co. Ltd.

During the trial operation of the southern extension section Shanghai Metro received complaints from residents of Pujiang Building on noise. In order to effectively control the impact of the noise caused by the train operation, on the premise of not affecting the overall capacity of line 5, a speed limit of was implemented between Station and Station.

There is currently a reserved and unopened station on the phase two extension of the line, which would be named station, located south of the current terminus at Fengxian Xincheng station. A further expansion of the second phase may see the line extended further south via Nanqiao town, Zhelin town to Haiwan town. The branch line between Dongchuan Road and Minhang Development Zone stations is expected to be replaced by Line 23, entirely underground, running to Shanghai Indoor Stadium station. Line 23 is expected to extend west from to Chedun on the Jinshan line. A north extension was planned to Plans have been abandoned as this extension is now part of the under construction Jiamin line.

Between 2014 and 2018 the signalling system of line 5 has been updated from the Siemens ZUB 200 to Thales SEC Transport TSTCBTC®2.0 (also deployed on Line 14). It is a unique dual CBTC system that features full redundancy and allows higher level of availability. This is China's first metro line that was deployed with a dual CBTC system. Shanghai Metro line 5 is China's first metro line where operation, renovation and construction were fulfilled at the same time. The project consisted of resignaling and expanding platforms of the existing section and adding a new south extension. To ensure no interruption to normal service, all the resignalling and commissioning was conducted in only a few hours during the night. Both before and after the commissioning, a switchover was made between the old and the new signaling system to ensure normal operation on the next day. After over 500 days, and more than 1,000 switchovers, line 5 had a seamless cutover to the new signalling system with no interruption to normal service at the end of 2018.
