SINGAPORE: The reliability of the MRT network, excluding the Thomson-East Coast Line (TEL), hit a record high in the 12 months ending September, according to the Land Transport Authority’s (LTA) monthly report published on Thursday (Oct 15).

The MRT network's mean kilometres between failures (MKBF) rose to 3.38 million train-km, up from 2.88 million train-km in August - at that time, a new record as well.

This marked the sixth consecutive month that the overall MRT network's MKBF exceeded 2 million train-km.

Individually, all five MRT lines included in the overall network figure had an MKBF above 1 million train-km.

A higher MKBF indicates better reliability. The September figures are provisional and subject to adjustment pending ongoing incident investigations. Transport Minister Jeffrey Siow said on Thursday that as Singapore's MRT network continues to grow, the focus will have to shift towards "more and better maintenance" as the number of assets increases and some begin to age. "We have to keep up the work that enables us to keep a high level of reliability," he told reporters at the Ten Mile Junction Depot. Mr Siow noted that the MRT network has recorded more than 2 million train-km between failures for six consecutive months, describing it as a "sustained period of good performance" that was "quite unprecedented". "We have never done (that) before," Mr Siow said of crossing the 3 million mark. He stressed, however, that the MKBF would "not continue to go up forever", noting that it is calculated on a rolling 12-month basis. Mr Siow pointed to the North East Line, which has not had a disruption for a year and has therefore reached what he described as the "theoretical maximum" for the metric.

Mr Siow pointed to the North East Line, which has not had a disruption for a year and has therefore reached what he described as the "theoretical maximum" for the metric.

The Thomson-East Coast Line (TEL) is not included in the overall reliability performance of the MRT network. This is because MKBF provides a reasonable indicator for reliability of mature rail lines but has its limitations, especially for newer ones, LTA said.

A newer rail line in its early stages tends to operate significantly lower mileage, especially since ridership remains relatively low and trains are not being operated at more typical frequencies, the authority said.

The latest MKBF figures improved across most MRT lines, with the exception of the Downtown Line, which saw its MKBF decline from 8.37 million train-km to 4.19 million train-km.

The MKBF for the Circle Line improved from 2.51 million train-km in August to 2.57 million train-km, while the North East Line's MKBF edged up to 4.5 million train-km from 4.48 million train-km.

The North-South Line and East-West Line also saw improvements, going up to 2.48 million train-km and 3.36 million train-km respectively.

The TEL's MKBF also rose to 498,000 train-km from 415,000 train-km in August.

LTA attributed the high MKBF levels over the past six months to the “sustained effort and dedication” of transport workers and rail operators to improve reliability and their response to faults and incidents, as well as ongoing upgrading and maintenance work.

"It also reflects the impact of the recommendations made by the Rail Reliability Taskforce in February 2026, which LTA, SMRT, and SBST have been following up on," LTA said.

The overall LRT network - which consists of Bukit Panjang LRT and Sengkang-Punggol LRT - had a dip in September, with its trains averaging 622,000 car-km between failures. The figure for August was 734,000 car-km.

Bukit Panjang LRT's MKBF remained unchanged at 443,000 car-km in September, while the Sengkang-Punggol LRT's fell to 776,000 car-km from 1.08 million car-km in August.

Mr Siow said renewal works on the Bukit Panjang LRT, which began in 2018, included replacing trains and upgrading its signalling and power systems, with the remaining works expected to be completed by the end of this year.

TRAIN SERVICE DELIVERY AND PUNCTUALITY

LTA also uses other metrics to measure rail reliability, including train service delivery and train punctuality.

Train service delivery measures how much of the scheduled train mileage was actually operated, while train punctuality measures the percentage of trips completed within two minutes of schedule at the end of a line or turnaround point.

The overall MRT network saw its train service delivery increase in September, up to 99.84 per cent. It was 99.62 per cent in August.

Three of the five MRT lines recorded improvements. The East-West Line was unchanged, while the North East Line declined.

The North-South Line increased to 99.96 per cent, while the Circle Line and Downtown Line went up to 99.79 per cent and 99.60 per cent, respectively.

The East-West Line saw no change in September, remaining at 99.96 per cent. The North East Line dropped to 99.86 per cent from 99.90 per cent.

For September, the overall MRT network saw an increase in its train punctuality. It went up to 99.36 per cent, from 99.03 per cent in August.

Only the North East Line saw a dip, while the rest of the lines went up.

The North East Line dropped to 98.61 per cent, from 99.08 per cent in August.

Train punctuality complements MKBF by tracking the consistency of rail operations and the predictability of journeys and wait times.

TEL's train punctuality and service delivery were 99.84 per cent and 99.99 per cent respectively in September.

Lower punctuality means that train frequencies are less regular, which can cause longer wait times and crowdedness, LTA said.

There were two MRT service disruptions lasting more than 30 minutes in the 12 months ending September, with LTA estimating that fewer than 5,000 passengers were affected in each incident.

This represented less than 1 per cent of the respective line's daily passengers, LTA said.

The incidents were on the East-West Line on Nov 11, 2025, and the Downtown Line on Sep 29, 2026.

"The severity of a service disruption can be measured not only by its length, but also by the number and proportion of passengers impacted," LTA said.

Mr Siow said faults and disruptions would still occasionally occur given the size and complexity of the rail network, adding that safety would remain the priority when operators respond to faults.

“We will work very hard to try to minimise those occurrences, as we have done,” he said.

新加坡：根据陆路交通管理局（LTA）周四（10月15日）发布的月度报告，截至9月份的12个月内，除汤申-东海岸线（TEL）外，地铁网络的可靠性创下历史新高。

地铁网络的平均故障间隔公里数（MKBF）上升至 338 万列车公里，高于 8 月份的 288 万列车公里——当时也创下了新纪录。

这标志着地铁网络总运力连续第六个月超过200万列车公里。

单独来看，计入整个网络数据的五条地铁线路的 MKBF 均超过 100 万列车公里。

CNA游戏 猜词游戏 逐行破解单词 流行词游戏 用给定的字母组成单词 迷你数独 小小的谜题，强大的脑力挑战 迷你填字游戏 小方格，大挑战 单词搜索 尽可能多地找出单词 显示更多 显示更少 陆路交通管理局 (LTA) 使用 12 个月移动平均值 MKBF 来发布其可靠性数据，MKBF 衡量的是延误超过五分钟前的平均行驶距离。MKBF 值越高，可靠性越好。9 月份的数据为暂定数据，可能会根据正在进行的事故调查结果进行调整。交通部长萧敬腾周四表示，随着新加坡地铁网络的不断发展，随着资产数量的增加和部分资产开始老化，工作重点必须转向“更多更好的维护”。他在十里路枢纽站车辆段对记者说：“我们必须继续努力，才能保持高水平的可靠性。”萧先生指出，地铁网络已连续六个月保持超过200万列车公里的无故障运行记录，他称之为“持续良好的运行状态”，并称其“前所未有”。萧先生在谈到突破300万列车公里大关时表示：“我们以前从未做到过这一点。”但他强调，无故障运行记录（MKBF）“不会一直上升”，并指出该指标是按滚动12个月计算的。萧先生以东北线为例，该线路已连续一年未发生故障，因此已达到他所说的该指标的“理论最大值”。

陆路交通管理局 (LTA) 使用 12 个月移动平均平均延误距离 (MKBF) 来发布其可靠性数据。MKBF 衡量的是延误超过五分钟前的平均行驶距离。MKBF 值越高，可靠性越好。

9月份的数据为暂定数据，将根据正在进行的事件调查结果进行调整。

交通部长萧敬腾周四表示，随着新加坡地铁网络的不断发展，随着资产数量的增加和部分资产开始老化，重点将不得不转向“更多更好的维护”。

“我们必须继续努力，才能保持高水平的可靠性，”他在十英里枢纽站告诉记者。

萧先生指出，地铁网络连续六个月未发生故障，累计运行里程超过 200 万公里，他称之为“持续良好的运行状态”，而且“前所未有”。

“我们以前从未做到过这一点，”萧先生在谈到突破300万大关时说道。

但他强调，MKBF“不会永远上涨”，并指出它是按滚动12个月计算的。

萧先生指出，东北线已经一年没有发生任何中断，因此达到了他所说的该指标的“理论最大值”。

汤申-东海岸线（TEL）并未纳入地铁网络的整体可靠性表现评估。陆路交通管理局（LTA）表示，这是因为MKBF指标虽然能较为合理地反映成熟线路的可靠性，但其局限性在于，尤其对于新建线路而言。

该机构表示，新建铁路在初期阶段的运营里程往往要少得多，尤其是在客流量仍然相对较低且列车运行频率尚未达到正常水平的情况下。

最新的 MKBF 数据显示，除市区线外，大多数地铁线路的 MKBF 均有所改善，市区线的 MKBF 从 837 万列车公里下降到 419 万列车公里。

环线列车运行量从 8 月份的 251 万列车公里提高到 257 万列车公里，而东北线列车运行量从 448 万列车公里小幅上升到 450 万列车公里。

南北线和东西线的运力也得到提升，分别达到 248 万列车公里和 336 万列车公里。

东京地铁的月均列车运行里程也从 8 月份的 415,000 列车公里增至 498,000 列车公里。

陆路交通管理局将过去六个月的高 MKBF 水平归功于交通运输工人和铁路运营商为提高可靠性和对故障和事故的响应而付出的“持续努力和奉献”，以及正在进行的升级和维护工作。

“这也反映了铁路可靠性工作组在 2026 年 2 月提出的建议的影响，陆路交通管理局、SMRT 和 SBST 一直在跟进这些建议，”陆路交通管理局表示。

包括武吉班让轻轨和盛港-榜鹅轻轨在内的整个轻轨网络在9月份出现下滑，列车平均故障间隔里程为62.2万车公里。8月份的这一数字为73.4万车公里。

9 月份，武吉班让轻轨的 MKBF 保持不变，为 443,000 车公里；而盛港-榜鹅轻轨的 MKBF 从 8 月份的 108 万车公里下降到 776,000 车公里。

萧先生表示，武吉班让轻轨的翻新工程于 2018 年启动，包括更换列车和升级信号及电力系统，剩余工程预计将于今年年底完成。

列车服务交付和准点率

陆路交通管理局还使用其他指标来衡量铁路可靠性，包括列车服务交付和列车准点率。

列车服务交付率衡量的是实际运行的列车里程占计划里程的比例，而列车准点率衡量的是列车在线路终点站或折返点两分钟内完成的行程百分比。

9月份，地铁整体服务交付率提升至99.84%，8月份为99.62%。

五条地铁线路中有三条线路的运营状况有所改善。东西线运营状况保持不变，而东北线运营状况则有所下降。

南北线的客运量增加到 99.96%，环线和市区线的客运量分别增加到 99.79% 和 99.60%。

9月份东西线的通行率没有变化，仍为99.96%。东北线的通行率从99.90%下降到99.86%。

9月份，地铁整体准点率有所提高，从8月份的99.03%上升至99.36%。

只有东北线的票价下降，其余线路的票价均上涨。

东北线通行率从 8 月份的 99.08% 下降至 98.61%。

列车准点率通过跟踪铁路运营的一致性以及旅程和等待时间的可预测性，对 MKBF 起到补充作用。

9 月份，TEL 的列车准点率和服务交付率分别为 99.84% 和 99.99%。

陆路交通管理局表示，准点率降低意味着列车班次不规律，这会导致候车时间延长和列车拥挤。

截至 9 月的 12 个月内，地铁服务中断超过 30 分钟，共发生两起事故，陆路交通管理局估计每起事故受影响的乘客不到 5000 人。

陆路交通管理局表示，这仅占该线路每日乘客量的不到 1%。

事件分别发生在 2025 年 11 月 11 日的东西线和 2026 年 9 月 29 日的市区线。

“服务中断的严重程度不仅要看中断持续时间，还要看受影响的乘客人数和比例，”陆路交通管理局表示。

萧先生表示，鉴于铁路网络的规模和复杂性，故障和中断仍会偶尔发生，并补充说，运营商在应对故障时仍将把安全放在首位。

他说：“我们将像过去一样，尽一切努力尽量减少此类事件的发生。”
