# Line 9 (Shanghai Metro)

Line 9 is a southwest-northeast line of the Shanghai Metro network. The line runs from Shanghai Songjiang Railway Station in Songjiang District to Caolu in Pudong. The line is colored light blue on system maps.

## History

In the initial planning of Line 9, the entire line was from Fengjing to Chongming Island. Later, the plan to extend to Fengjing was cancelled, and the section to Chongming Island was changed to Chongming line.
The first phase of Line 9, from Songjiang Xincheng to Guilin Road stations, opened on December 29, 2007. It uses the Bombardier Movia trains which were lended to line 1.
Line 9 did not directly connect to the rest of the Shanghai Metro network until the opening of the Line 9 portion of the Yishan Road station on December 28, 2008. The station is an interchange between lines 3 and 4. A shuttle bus conveyed passengers between Guilin Road and Yishan Road stations until construction was completed.
In December 2009, the second phase of line 9 (from Yishan Road to Century Avenue) was completed, providing passengers with a direct link from Songjiang District in the west to Pudong in the east without having to transfer to other lines.
On April 7, 2010, the extension to Middle Yanggao Road Station was completed.
On December 30, 2012, the extension from Songjiang New City to Songjiang South Railway Station was opened.
On December 30, 2017, the line's east extension, consisting of 9 stations from Middle Yanggao Road to Caolu, entered operation.

## Stations
### Important stations

* Songjiang University Town- the collection of several top universities in Shanghai, including Donghua University, Shanghai International Studies University, East China University of Politics and Law, Shanghai Institute of Foreign Trade are located there.
* Sheshan - serving Sheshan Hill, a tourist and pilgrimage destination with the Sheshan Observatory and the Sheshan Basilica.
* Qibao - serving the old town of Qibao.
* Caohejing Hi-Tech Park - serving the high-tech park Caohejing.
* Xujiahui - one of the busiest metro stations in Shanghai, with shopping malls and office buildings in the vicinity; interchange with lines 1 and 11.
* Century Avenue - a major interchange station on four lines - Interchange with lines 2, 4 and 6.
* Sijing - Sijing Station, located in Songjiang District, Shanghai, is an elevated side platform station on Line 9 of the Shanghai Metro, opened on December 29, 2007. From 2019 to 2023, Sijing has consistently been the busiest metro station in all of Shanghai, with no other station able to surpass it. The reason why Sijing Station in Shanghai's Songjiang District is consistently the busiest metro station is due to its location in a densely populated residential area, limited alternative transportation options, and its role as a key transit hub for commuters heading to industrial zones, educational institutions, and central Shanghai. As a stop on Line 9, Sijing connects the district to the city's core, leading to heavy passenger flows, particularly during rush hours. Frequent human flow restrictions in the station reflect the station’s struggle to manage the immense crowding it experiences daily.
* Yishan Road - Located on Kaixuan Road in Xuhui District, Shanghai, Yishan Road Station serves as an interchange hub for Lines 3, 4, and 9. It plays a critical role in connecting different parts of the city through multiple lines, making it an important stop on the network.

### Incidents

In the early hours of November 7, 2010, at around 1:50 AM, a pressurization incident occurred at Shanghai Jianhua Concrete Pile Co., Ltd., located at 2033 Husong Road. During the pressurization process, a component of the No. 1 autoclave in Workshop A suddenly broke loose. The part crashed through the outer wall and struck the southern pillar of the No. 51 bridge on Metro Line 9. Fortunately, the incident occurred during non-operational hours. However, train services between Jiuting station and Songjiang New Town station had to be temporarily suspended, and trains were limited to a speed of 10 km/h.
On February 23, 2024, at 6:25 AM, operations on the section of Line 9 between Songjiang South Station and Jiuting Station were suspended due to ice accumulation on the overhead contact line. A bus bridging plan was activated, and by 9:37 AM, normal operations resumed. This was the first time that such an issue had occurred on the Shanghai Metro.
On the morning of June 19, 2024, at 8:28 AM, an indiscriminate stabbing incident happened at the Hechuan Road Station on Shanghai Metro Line 9, near the station’s exit. The incident occurred during the busy rush hour, when the station was crowded with commuters going about their daily routines. The attacker, seemingly acting without any clear motive, began randomly attacking innocent passengers with a knife, causing chaos among the people in the vicinity. Three people were injured, and the attacker was apprehended by the police. Following the incident, Hechuan Road Station was temporarily closed to allow authorities to manage the situation, and normal operations resumed at 9:16 AM. In the aftermath, the security system of the Shanghai Metro was widely questioned. Some critics expressed concerns, arguing that the existing security measures may not be capable of preventing such a violent act. They pointed out that with millions of passengers using the metro daily, maintaining robust security should be the top priority to safeguard public safety.
On the other hand, others have acknowledged the challenges faced by the metro system in Shanghai, particularly during peak hours. They pointed out that while security is crucial, the sheer volume of commuters makes it difficult to implement thorough checks without causing significant delays. The Shanghai Metro is one of the busiest transit systems in the world, and balancing passenger safety with the need for efficiency is a complex issue. Stringent security measures could slow down operations, particularly during rush hour when the metro is operating at full capacity. This debate highlights the ongoing challenge for large urban transit systems like Shanghai’s Metro.

### Future expansion

The east section is planned to extend one station to Caolu Railway station.

### Station name change

* On 28 October 2006, Dongfang Road was renamed as the Century Avenue after station renovation for line 2 and the opening of line 4 (before line 9 began serving the station).

### Former Rolling Stock

One train (0952) manufactured in 2007 was mainly debugged for experimental purposes. It began trial operation with passengers on April 25, 2009, and will no longer be operational in 2010. On December 20, 2011, the vehicle was retired from line 9 and became a special training vehicle. It was transferred to the original Zhangjiang Hi-Tech Park of line 2 to the newly built Longyang Road training line for subway staff training.
