The Land Transport Authority (LTA) has awarded a contract to PBT Engineering Pte Ltd to design and install 5.5km of railway noise barriers at 16 elevated locations along the North-South and East-West Lines (NSEWL).
2 This is the third phase of LTA’s railway noise barrier programme, which aims to reduce the impact of railway noise near residential areas. It will benefit residents living along the East-West Line (EWL) from Pasir Ris to Kembangan stations, as well as those living along the North-South Line (NSL) from Jurong East to Khatib stations. When completed in 2023, the noise barriers are expected to reduce noise levels from passing trains by about 5 to 10 decibels (See Annex for an overview of the implementation of railway noise barriers).
Types of noise barriers
3 The type of railway noise barriers installed depends on the noise level and profile of tracks. For example, noise barriers installed at turnout sections – where trains switch tracks – have a semi-enclosed “portal” design to handle the higher noise levels, whereas those along plainline or straight tracks are vertical. The portal design for noise barriers will be used for the stretch of railway tracks between Yio Chu Kang and Ang Mo Kio stations on the NSL.
