LTA calls tender for rail dampers to reduce noise on Thomson-East Coast Line stretches

The rail dampers are planned for locations with tighter track curves, including stretches between Springleaf and Lentor, Stevens and Napier, and Bright Hill and Upper Thomson stations.

SINGAPORE: The Land Transport Authority (LTA) will call a tender to install rail dampers along noisier stretches of the Thomson-East Coast Line (TEL), as an extra measure to address commuter feedback about rail noise.

LTA told CNA that its ongoing efforts include slowing trains in certain areas and grinding the track surface.

In a Facebook post on Tuesday (Oct 6), LTA said that it has also been trailling noise-reduction measures at selected locations, which have shown positive results.

Rail dampers are devices installed onto rails that absorb track vibrations and reduce noise emissions as trains pass over them.

There will be no impact on train services because the installation will be done during engineering hours, LTA said, adding that it will continue to closely monitor the noise levels and adjust its measures as necessary. The authority also said that the move builds on its ongoing trials of noise-reduction measures, which have shown positive results. "We will continue to work closely with our public transport operators to monitor noise levels and improve your journeys." LTA's Facebook post also highlighted feedback about rail noise, including a post on online forum Reddit, in which someone described parts of the MRT line as "deafening". In a 2023 media reply to a letter about noise levels on the TEL, Mr Yee Boon Cheow, then LTA's group director of rail (electrical and mechanical), said that the authority and public transport operators closely monitored noise levels on all MRT lines. He also said that all underground MRTs are generally kept to an interior noise threshold of 85 decibels LAeq. Still, the threshold may be exceeded along certain stretches of the TEL due to the track curvature in those areas. "The curved track alignment was necessary to minimise the need to acquire land from residents and shorten commuting time for all passengers." He added that mitigation measures had been implemented, including slowing the trains in those areas and grinding the track surface to smooth the contact between the tracks and wheels.

计划在轨道曲线较急的路段安装轨道阻尼器，包括 Springleaf 和 Lentor 之间、Stevens 和 Napier 之间以及 Bright Hill 和 Upper Thomson 站之间的路段。

新加坡：陆路交通管理局 (LTA) 将公开招标，在汤申-东海岸线 (TEL) 噪音较大的路段安装轨道减震器，作为一项额外措施，以回应通勤者对铁路噪音的反馈。

陆路交通管理局告诉亚洲新闻台，他们正在采取的措施包括在某些地区减慢列车速度和打磨轨道表面。

陆路交通管理局周二（10月6日）在Facebook上发帖称，他们还在一些特定地点试行降噪措施，并取得了积极的成效。

轨道阻尼器是安装在铁轨上的装置，用于吸收轨道振动，减少列车通过时产生的噪音。

陆路交通管理局的 Facebook 帖子还重点介绍了有关铁路噪音的反馈，包括 Reddit 在线论坛上的一篇帖子，其中有人将地铁线路的部分路段描述为“震耳欲聋”。

2023 年，陆路交通管理局 (LTA) 时任铁路（电气和机械）集团总监余文超先生在回复媒体关于汤申-东港线 (TEL) 噪音水平的信件时表示，管理局和公共交通运营商密切监测所有地铁线路的噪音水平。

他还表示，所有地铁的内部噪音通常都控制在85分贝（LAeq）以内。不过，由于汤申-东南线（TEL）某些路段的轨道弯曲，噪音可能会超过这个阈值。

“采用弧形轨道布局是为了最大限度地减少征用居民土地的需要，并缩短所有乘客的通勤时间。”

他还补充说，已经实施了缓解措施，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。
