【国会发言】新加坡交通部长徐芳达：地铁遇紧急情况中断服务，可免费换乘巴士

(a) 对 2024 年 6 月 3 日地铁中断的调查发现电力牵引故障的原因是什么？(b) 地铁系统目前的防雷保护是否足够？

(c) 如何防止未来发生此类中断？

(d) 此类重大事件的应急措施是什么？

(e) 交通部是否会同意为油池和林邦地区的居民提供更多交通选择？

89 林谋泉（蒙巴登单选区议员）先生询问交通部长：

是否定期审查公共交通运营商采取的沟通和人群控制措施，以通知受地铁列车故障影响的乘客？

徐芳达（交通部长）先生：我的答复将涉及今天会议的第88和89号问题以及第70号书面问题。

对2024年6月3日南北线中断事件的调查正在进行中。我们已经确定，当日下午5点46分左右，克兰芝地铁站附近的轨道旁一户外电源控制箱遭雷击损毁。根据陆交局 (LTA) 的初步调查，为保护电力控制箱免受雷击而设计的避雷针未能按预期运行。这导致了牵引电力的损失和列车服务的中断。

新加坡地铁(MRT) 网络的当前防雷系统符合本地和国际标准，以确保我们乘客的安全。在2024年6月3日发生这起事件之前，过去五年中没有发生过列车因雷击中断服务的事故。

运营商一直遵守避雷器制造商建议的维护制度。由于克兰芝和马西岭之间的这段铁轨是雷击多发路段，过去的雷击可能加速了避雷器的老化。有鉴于此，我们正与生产商和铁路运营商合作，对避雷器的维护频率进行审查。我们已更换了出现问题的避雷器，并检查了附近的其他避雷器，发现均处于正常工作状态。

陆交局要求铁路运营商在服务中断的情况下制定强有力的应对计划。这些计划包括提供替代交通选择，例如在受影响的车站免费搭乘巴士，以及提供接驳巴士服务。陆交局、铁路运营商和其他相关机构每年都会联合演练这些计划。从事故和演习中吸取的经验教训有助于陆交局和我们的运营商不断改进事故响应计划。

对于6月3日的中断事故，陆交局（LTA）评估认为运营方已按照标准作业程序作出响应。尽管如此，陆交局（LTA）已注意到这次中断事故带来的反馈，并正在与铁路运营商合作，以加强他们的事故管理计划。这些措施包括提高服务中断期间公共广播的清晰度，改善受影响地铁站和接驳巴士上车点的人流控制措施。

任梓銘先生询问油池和林邦地区的交通选择。油池和林邦居民可在油池地铁站乘坐南北线，也可乘坐巴士连接东西线和滨海市区线。到2030年代中期，当滨海市区线从武吉班让站延伸至新的双溪加株换乘站后，油池和林邦居民将能更方便地前往滨海市区线。 

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.
