LTA calls tender to install rail dampers on Thomson-East Coast Line to reduce noise from tight track curves without affecting train services. Read more at straitstimes.com.
The rail dampers will be installed where higher noise levels are observed due to tighter track curvatures, LTA said.

LTA is tendering to install rail dampers on the Thomson-East Coast Line to reduce noise at curved track sections causing higher noise levels.
Noise reduction measures like slowing trains and track grinding have been used; dampers will be installed without affecting train services during overnight engineering hours.
TEL is Singapore's newest MRT line, with final stage opening in 2026; LTA will keep monitoring noise and adjust measures as needed.
SINGAPORE – To address feedback about rail noise, the Land Transport Authority (LTA) is calling a tender to install noise reduction devices along some stretches of the Thomson-East Coast Line (TEL).
The authority said in a Facebook post on Oct 6 that these devices, called rail dampers, will be installed where there are h igher noise levels due to tight track curvatures .
These include stretches between Springleaf and Lentor stations, between Stevens and Napier stations, and between Bright Hill and Upper Thomson stations.
Rail dampers are devices fixed onto rails that absorb track vibrations and reduce noise emissions as trains pass over them.
In a 2023 forum reply in The Straits Times concerning TEL noise levels, LTA said all of Singapore’s underground MRT lines are generally kept to an interior noise threshold of 85 decibels LAeq (a measurement of sound pressure over a period of time).
LTA had said then that it was aware there are some areas along the TEL where this noise threshold may be exceeded, citing the three stretches listed above .
The curved track alignment was necessary to minimise the need to acquire land from local residents and shorten the commuting time for all passengers, LTA added.
Mitigation measures had been implemented to reduce noise levels on the line, including slowing down the trains in these areas, and grinding the surface of the tracks to smoothen the contact between the tracks and wheels, LTA said in its 2023 reply.
“As part of our ongoing efforts, we have been trialling noise reduction measures at selected locations, with positive results,” LTA said in its Oct 6 post.
The installation of the dampers will not impact train services, LTA said. It added that work will be carried out during engineering hours, which refers to the overnight window between train operations.
The TEL is Singapore’s sixth MRT line, and its newest one in service. TEL Stage 5, the final stretch of the line which will add two more stations – Bedok South and Sungei Bedok – is expected to open in the second half of 2026 .
Spanning more than 40km , the TEL is operated by rail operator SMRT Trains, which also runs the North-South Line, East-West Line, Circle Line, and the Bukit Panjang LRT.
LTA said it will continue to closely monitor noise levels and adjust its measures as necessary.

陆路交通管理局正在招标在汤申-东海岸线上安装轨道阻尼器，以降低弯道轨道区域较高的噪音水平。
已采取减速列车和打磨轨道等降噪措施；将在夜间工程施工期间安装阻尼器，不会影响列车服务。
汤申-东线是新加坡最新的地铁线路，最终阶段将于 2026 年开通；陆路交通管理局将持续监测噪音，并根据需要调整措施。
新加坡——为了回应有关铁路噪音的反馈，陆路交通管理局（LTA）正在招标，计划在汤申-东海岸线（TEL）的部分路段安装降噪装置。
该机构在 10 月 6 日的 Facebook 帖子中表示，这些被称为轨道阻尼器的装置将安装在轨道弯曲度较大、噪音水平较高的地方。
其中包括 Springleaf 站和 Lentor 站之间的路段、Stevens 站和 Napier 站之间的路段以及 Bright Hill 站和 Upper Thomson 站之间的路段。
轨道阻尼器是固定在铁轨上的装置，用于吸收轨道振动，减少列车通过时产生的噪音。
2023 年，《海峡时报》在论坛上回复有关 TEL 噪音水平的问题时，陆路交通管理局表示，新加坡所有地铁线路的内部噪音阈值通常保持在 85 分贝 LAeq（一段时间内的声压测量值）。
当时陆路交通管理局表示，他们意识到汤申-东南线沿线某些区域的噪音可能会超过该阈值，并列举了上述三个路段。
陆路交通管理局补充说，采用弯曲轨道走向是为了最大限度地减少向当地居民征地，并缩短所有乘客的通勤时间。
陆路交通管理局在 2023 年的答复中表示，已采取缓解措施来降低该线路的噪音水平，包括降低这些区域的列车速度，以及打磨轨道表面以使轨道和车轮之间的接触更加顺畅。
“作为我们持续努力的一部分，我们一直在选定地点试行降噪措施，并取得了积极的成果，”陆路交通管理局在10月6日的帖子中表示。
陆路交通管理局表示，安装阻尼器不会影响列车服务。管理局补充说，施工将在工程时段进行，即列车夜间运行间隙。
汤申-东线（TEL）是新加坡的第六条地铁线路，也是目前最新投入运营的线路。汤申-东线第五阶段，即该线路的最后一段，将新增两个车站——勿洛南站和双溪勿洛站——预计将于2026年下半年开通。
汤申-东南线 (TEL) 全长超过 40 公里，由地铁运营商 SMRT Trains 运营，该公司还运营南北线、东西线、环线和武吉班让轻轨。
陆路交通管理局表示，将继续密切监测噪音水平，并根据需要调整应对措施。
