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. [13] 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. [14] 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. [15] 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.
