Singapore's MRT network, excluding the Thomson-East Coast Line (TEL), recorded its 10th month without a major delay of more than 30 minutes in August.
The monthly rail reliability report published by the Land Transport Authority (LTA) also stated that the overall MRT network’s Mean Kilometres Between Failure (MKBF) exceeded two million train-km for a fifth consecutive month.
All MRT lines’ MKBF remain above one million train-km, including the oldest North-South (NSL) and East-West Line (EWL), said LTA on Friday (Sept 11).
Rail reliability is mainly tracked using a 12-month moving average of the MKBF metric, which counts the average distance a train travels before it meets a delay of over five minutes.
The provisional data shows the overall network's MKBF rose to 2.88 million train-km, up from the 2.37 million train-km in July.
It also shows that all five mature MRT lines — NSL, EWL, North-East Line (NEL), Circle Line (CCL) and the Downtown Line (DTL) — either maintained or improved their 12-month MKBF moving average.
The DTL saw the biggest improvement in its MKBF from the 4.2 million train-km in July to 8.37 million in August. This was followed by the EWL which recorded 2.52 million train-km in its MKBF, up from the 2.02 million in July.
"Our high MKBF levels over the last five months reflect their sustained effort and dedication to uplift reliability and improve their response to faults and incidents," LTA said.
It added that this performance also reflects the impact of the recommendations made by the Rail Reliability Task Force in February this year, which the authority said it is working with train operators SMRT and SBS Transit to implement.
Meanwhile, MKBF for TEL — increased from 373,000 train-km in July to 415,000 train-km in August.
TEL is not included in the overall MRT network's MKBF as it is still undergoing construction and extension, and system integration works are ongoing alongside regular operations and maintenance.
Train service delivery and train punctuality
Two other metrices used by LTA to track rail reliability — train service delivery and train punctuality — also remained high at above 99 per cent in August.
Train service delivery measures the actual distance travelled by trains compared to the scheduled distance, while train punctuality measures the extent to which train trips are completed on time.
Both the NEL and CCL recorded improvements on their train service delivery, while the NSL and DTL saw their performance on this metric drop slightly.
Overall, the MRT network recorded train service delivery of 99.62 per cent in August.
Meanwhile, train punctuality on the overall network dipped slightly from 99.29 per cent in June, to 99.03 per cent in August.
Of the five mature MRT lines, CCL recorded an improvement, while the other four lines saw a dip in performance.
LTA noted that both metrices for the DTL were lower in August owing to planned system integration testing.
新加坡地铁网络（不包括汤申-东海岸线）在8月份连续第10个月没有出现超过30分钟的重大延误。
陆路交通管理局 (LTA) 发布的月度铁路可靠性报告还指出，地铁网络的平均故障间隔里程 (MKBF) 连续第五个月超过 200 万列车公里。
陆路交通管理局周五（9月11日）表示，所有地铁线路的MKBF（列车运行里程）均超过100万列车公里，包括最老的南北线（NSL）和东西线（EWL）。
铁路可靠性主要通过 MKBF 指标的 12 个月移动平均值来跟踪，该指标计算列车在延误超过 5 分钟之前平均行驶的距离。
初步数据显示，整个网络的 MKBF 增至 288 万列车公里，高于 7 月份的 237 万列车公里。
报告还显示，所有五条成熟的地铁线路——南北线、东西线、东北线、环线和市区线——都保持或提高了其 12 个月的 MKBF 移动平均值。
都柏林交通运输公司（DTL）的列车运行里程（MKBF）增幅最大，从7月份的420万列车公里增至8月份的837万列车公里。其次是东西铁路公司（EWL），其列车运行里程（MKBF）从7月份的202万列车公里增至8月份的252万列车公里。
“过去五个月我们较高的 MKBF 水平反映了他们为提高可靠性和改善对故障和事故的响应而持续付出的努力和奉献精神，”陆路交通管理局表示。
该机构还表示，这一业绩也反映了铁路可靠性工作组今年 2 月提出的建议的影响，该机构表示正在与列车运营商 SMRT 和 SBS Transit 合作落实这些建议。
与此同时，TEL 的 MKBF 从 7 月份的 373,000 列车公里增加到 8 月份的 415,000 列车公里。
由于汤申-东南线 (TEL) 仍在建设和扩建中，并且系统集成工作与日常运营和维护同时进行，因此它不包含在整个地铁网络的 MKBF 中。
列车服务交付和列车准点率
陆路交通管理局用来追踪铁路可靠性的另外两项指标——列车服务交付率和列车准点率——在 8 月份也保持在 99% 以上的高位。
列车服务交付衡量列车实际行驶距离与预定行驶距离的比较，而列车准点率衡量列车行程按时完成的程度。
东北线 (NEL) 和环城线 (CCL) 的列车服务交付情况均有所改善，而南北线 (NSL) 和市中心线 (DTL) 在该指标上的表现略有下降。
总体而言，地铁网络8月份的列车服务交付率为99.62%。
与此同时，整个铁路网的列车准点率从 6 月份的 99.29% 略微下降到 8 月份的 99.03%。
在五条成熟的地铁线路中，环城线（CCL）的运营效率有所提高，而其他四条线路的运营效率则有所下降。
LTA指出，由于计划中的系统集成测试，8月份DTL的两项指标均有所下降。
