The Government is deeply concerned about the train incident on the MTR Tseung Kwan O Line yesterday evening (May 22). At around 5.15pm, the Government received notification from the MTR Corporation Limited (MTRCL) that, due to failure of the traction power supply system, Tseung Kwan O Line services were disrupted and then fully suspended.

     Upon receiving notification of the incident from the MTRCL, the Electrical and Mechanical Services Department (EMSD) immediately deployed professional railways and electrical engineers to the site to assess the situation and conduct investigation of the incident. Preliminary findings indicated that a section of the overhead cable was found faulted in the tunnel of the Tseung Kwan O Line (Tseung Kwan O Station to Yau Tong Station direction) near Quarry Bay Station. The traction power supply system was tripped when the train passed through the section. The EMSD also found signs of damage to the overhead cable at the scene of the incident. It is initially suspected that the cause of incident was related to the damage of cable components. Detailed investigation is ongoing.

     The EMSD will continue with its overnight investigation at the scene on the traction power supply system, and inspect incident train at the depot. The investigation encompasses the consideration of power distribution system, train components, environmental conditions and human factors, etc. The EMSD has requested the MTRCL to conduct a comprehensive review on the incident and submit an investigation report as soon as possible to explain the cause of the incident and propose improvement measures to prevent recurrence of similar incidents.
