Singapore awards another railway noise barrier contract

Singapore’s Land Transport Authority awarded PBT Engineering a contract to design and install 5.5 km of railway noise barriers at 16 elevated locations along the North-South and East-West Lines (NSEWL). When completed in 2023, the noise barriers are expected to reduce noise levels from passing trains by about 5 to 10 decibels.
The type of railway noise barriers installed depends on the noise level and profile of tracks. 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 plain line 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.
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.
The first phase, which comprises 11.5 km railway noise barriers, was completed in 2018. On-site works for another 10 km of noise barriers under second phase are ongoing and are expected to be installed by the third quarter of 2020 as scheduled.
The completion of the third phase will bring the total length of railway noise barriers installed across the island to 27 km.
