2024年7月2日，新加坡交通部長徐芳達在國會書面答覆馬西嶺--油池集選區議員任梓銘、蒙巴登單選區議員林謀泉有關6月3日南北線地鐵中斷的原因及未來改善的努力。
以下內容為新加坡眼根據國會英文資料翻譯整理：
任梓銘（馬西嶺--油池集選區議員）先生詢問交通部長：
(a) 對 2024 年 6 月 3 日地鐵中斷的調查發現電力牽引故障的原因是什麼？(b) 地鐵系統目前的防雷保護是否足夠？
(c) 如何防止未來發生此類中斷？
(d) 此類重大事件的應急措施是什麼？
(e) 交通部是否會同意為油池和林邦地區的居民提供更多交通選擇？
89 林謀泉（蒙巴登單選區議員）先生詢問交通部長：
是否定期審查公共運輸運營商採取的溝通和人群控制措施，以通知受地鐵列車故障影響的乘客？
徐芳達（交通部長）先生：我的答覆將涉及今天會議的第88和89號問題以及第70號書面問題。
對2024年6月3日南北線中斷事件的調查正在進行中。我們已經確定，當日下午5點46分左右，克蘭芝地鐵站附近的軌道旁一戶外電源控制箱遭雷擊損毀。根據陸交局 (LTA) 的初步調查，為保護電力控制箱免受雷擊而設計的避雷針未能按預期運行。這導致了牽引電力的損失和列車服務的中斷。
新加坡地鐵(MRT) 網絡的當前防雷系統符合本地和國際標準，以確保我們乘客的安全。在2024年6月3日發生這起事件之前，過去五年中沒有發生過列車因雷擊中斷服務的事故。
運營商一直遵守避雷器製造商建議的維護制度。由於克蘭芝和馬西嶺之間的這段鐵軌是雷擊多發路段，過去的雷擊可能加速了避雷器的老化。有鑒於此，我們正與生產商和鐵路運營商合作，對避雷器的維護頻率進行審查。我們已更換了出現問題的避雷器，並檢查了附近的其他避雷器，發現均處於正常工作狀態。
陸交局要求鐵路運營商在服務中斷的情況下制定強有力的應對計劃。這些計劃包括提供替代交通選擇，例如在受影響的車站免費搭乘巴士，以及提供接駁巴士服務。陸交局、鐵路運營商和其他相關機構每年都會聯合演練這些計劃。從事故和演習中吸取的經驗教訓有助於陸交局和我們的運營商不斷改進事故響應計劃。
對於6月3日的中斷事故，陸交局（LTA）評估認為運營方已按照標準作業程序作出響應。儘管如此，陸交局（LTA）已注意到這次中斷事故帶來的反饋，並正在與鐵路運營商合作，以加強他們的事故管理計劃。這些措施包括提高服務中斷期間公共廣播的清晰度，改善受影響地鐵站和接駁巴士上車點的人流控制措施。
任梓銘先生詢問油池和林邦地區的交通選擇。油池和林邦居民可在油池地鐵站乘坐南北線，也可乘坐巴士連接東西線和濱海市區線。到2030年代中期，當濱海市區線從武吉班讓站延伸至新的雙溪加株換乘站後，油池和林邦居民將能更方便地前往濱海市區線。
以下是英文質詢內容：
Mr Alex Yam Ziming asked the Minister for Transport (a) what have investigations into the MRT disruption on 3 June 2024 found to be the cause of the power traction failure; (b) whether current lightning protection for the MRT system is adequate; (c) how can future occurrences of such disruptions be prevented; (d) what are the contingencies for such major incidents; and (e) whether the Ministry will accede to providing more transport options for residents of Yew Tee and Limbang estates.
Mr Lim Biow Chuan asked the Minister for Transport whether the Ministry regularly reviews the communication and crowd control measures adopted by the public transport operators to notify commuters affected by breakdown of MRT trains.
Mr Chee Hong Tat: My reply will address Question Nos 88 and 89, as well as Written Question No 70 for today’s Sitting.
The investigation into the disruption on the North-South Line on 3 June 2024 is ongoing. We have established that a lightning strike damaged an outdoor trackside power control box near Kranji station at around 5.46 pm. Based on the Land Transport Authority's (LTA’s) preliminary investigation, the surge arrester that was designed to protect the power control box against lightning strikes did not operate as intended. This caused a loss of traction power and the disruption to train service.
The current lightning protection systems for our Mass Rapid Transit (MRT) network comply with local and international standards to ensure the safety of our commuters. Until this incident on 3 June 2024, there had been no train disruptions due to lightning strikes in the past five years.
The operator had adhered to the maintenance regime recommended by the manufacturer for the surge arrester. It is possible that past lightning strikes had accelerated the deterioration of this particular surge arrester, as this section of the track between Kranji and Marsiling is lightning-prone. Arising from this incident, we are working with the manufacturer and the rail operators to review the maintenance frequency of surge arresters. We have replaced the surge arrester in question, and the other surge arresters in the vicinity have been checked and found to be in working condition.
LTA mandates that rail operators have in place robust response plans in the case of service disruptions. These plans include providing alternative transportation options, such as free bus boarding at affected stations and bridging bus services. LTA, rail operators and other relevant agencies jointly exercise these plans annually. Learning points from incidents and exercises help LTA and our operators to make continual improvements to their incident response plans.
For the 3 June disruption, LTA has assessed that the operator had responded in accordance with the standard operating procedures. Nevertheless, LTA has taken note of the feedback arising from the disruption and are working with the rail operators to strengthen their incident management plans. These include improving the clarity of public announcements during service disruptions and improving crowd control measures for affected MRT stations and at boarding points for bridging buses.
Mr Alex Yam asked about transport options for Yew Tee and Limbang. Yew Tee and Limbang residents are served by the North-South Line at Yew Tee station and are also connected to the East-West Line and Downtown Line by bus services. By the mid-2030s, Yew Tee and Limbang residents will have better access to the Downtown Line when it is extended beyond Bukit Panjang station towards a new Sungei Kadut interchange station.
