Line 15 (Shanghai Metro)

Line 15 of the Shanghai Metro is a north-south metro line in the city of Shanghai that opened on 23 January 2021. The line begins at Gucun Park in Baoshan District at its northern end, and terminates at Zizhu Hi-tech Park in Minhang District at its southern end, via Shanghai West Railway Station and Shanghai South Railway Station. It will be 42.3 kilometres (26.3 mi) in length and have 30 stations. The line is one of Shanghai Metro's new batch of high capacity fully automated and driverless lines along with Lines 14 and 18. The line is colored ivory on system maps.

History

The line was originally scheduled to open by the end of 2020. However, on 24 December 2020, Shanghai Metro officials announced that the opening would take place in 2021, prior to the start of the Chinese New Year. Line 15 opened on January 23, 2021. Guilin Road station opened on June 27, 2021.

On January 19, 2021, there was a partial collapse in an under-construction Exit 9 of Zizhu Hi-tech Park station. There were no casualties at the scene, no impact on the surrounding environment, and no impact on the opening of Line 15.

On May 20, 2021, according to the official announcement, due to the accumulation of water between Loushanguan Road and East China University of Science and Technology, Line 15 will operate at a speed limit, which is expected to be delayed for more than 25 minutes.

Controversy

On 28 December 2011, the northern terminus of the line was shifted from Qihua Road station to an independent station called Jinqiu Road, located near Line 7 between Qihua and Shanghai University but with no direct interchange to Line 7. This has stirred controversy among residents over Line 15's already lack of convenient connections with other major subway lines such as Line 2 and Line 10. Planners reconsidered and extended Line 15 north of Jinqiu Road to connect with Line 7 at Gucun Park. In December 2019, the line was further revised to provide an interchange with Line 2 at Loushanguan Road station. However, there is still no interchange planned with Line 10, as the Line 15 Hongbaoshi Road station is located mid-way between Yili Road and Shuicheng Road stations on Line 10.

Signalling

Line 15 is notable for being driverless and the longest line in China operating GoA4 (Grade-of-Automation 4), whereby trains may operate automatically at all times, including the actions of opening/closing doors, detecting obstacles and reacting to emergencies. There are no staff on board concerned with ongoing train operations.

Between December 2020 and January 2021, SATEE supplied its OptONIX and ONIX metro traction systems for 324 metro cars of Shanghai Line 15, with support from Xi'an Alstom Yongji Electric Equipment Co. Ltd (XAYEECO). It was also responsible for the train control monitoring system (TCMS) of Shanghai Line 15, and the line's train electrical design. During the same period, CASCO has successfully put into service its Urbalis 888 signalling solution on six of these metro lines in Chengdu and Shanghai.
