THOUSANDS of morning riders on Line 11 from Futian to Bitou were stranded at stations yesterday as part of the line had to suspend service due to an illegal ground piling project that pierced through the tunnel near Houhai Station, the interchange station of Line 11 and Line 2.

A Metro train running from Hongshuwan South Station to Houhai Station hit the pile and was seriously damaged, but no one was injured in the incident, according to an investigation report released by Shenzhen Metro Co. yesterday.

Metro service from Hongshuwan South Station to Houhai Station resumed at 7:48 p.m., 12 hours after the incident.

Shenzhen police received a report at around 7 a.m. from Shenzhen Metro Co., saying the tunnel near Houhai Station had been pierced by an illegal piling project at the construction site east of Shenzhen Bay Sports Center.

An investigation showed the contractor, Zhengye Construction Co. Ltd., began piling for a rock climbing base construction project in the safety control area of Shenzhen Metro operation without having applied to Shenzhen Metro Co. in advance. The pile, which is about 20 meters in depth, went through the tunnel and a section of it was knocked off by a passing train. The pile also damaged other facilities, such as a contact wire net, resulting in a large number of commuters being stranded at stations along the line.

Only when law enforcement officers arrived on the scene did the construction workers realize they had caused a lot of trouble. The manager at the construction site refused to comment.

According to Zhou Tao, an employee with the Shenzhen Metro Management and Operation Office, there are 12 pits for piling at the construction site. Each pile pit is 20 meters in depth and 60 centimeters in diameter.

Shenzhen Metro Co. responded immediately after the incident, and according to its release at 2:30 p.m. yesterday, the rescue work needed about five hours.

Many riders complained about the halt in service that made them late for work and expressed anger after they learned the cause of the incident.

Netizen @liululu666xi complained about being four hours late to the office, while another netizen wept all the way due to being made late for an important examination.

This was the second Metro accident caused by illegal piling at a construction site in 40 days.

On Oct. 28, a piling job for a housing estate at the construction site of Shenzhen Bay Super Headquarters in Nanshan District broke through the tunnel of Metro Line 9, causing a mud cave-in. Thanks to the alert from Metro train drivers who spotted the abnormal situation and reported it to the commanding and maintenance teams, the Metro avoided further damage.

An investigation showed that the contractor of the housing project had violated rules and started piling prior to applying for approval. Two people were criminally detained.

According to regulations on the city's rail transportation management, contractors within the Metro operation areas must apply for written approval from the Metro operator before commencing piling work.
