CISILENT® TYPE G PILOT PROJECT IN WENZHOU (CN): NOISE PROTECTION ON THE S 1 RAILWAY TRACK


The S1 suburban railway line in Zhenjiang Wenzhou, with a permissible speed of 140 km/h, is largely designed as an elevated track. To protect the residents from noise, the operator needed a noise barrier made of highly sound-absorbing elements that noticeably reduce the noise of the track. There was only a short time window of a few hours available for the installation, during the nightly closure breaks, which made a quick and easy installation necessary. The choice fell on Cisilent® Type G, a system in lightweight construction that offers high sound absorption even in low frequency ranges at a low construction height.

Laboratory tests confirmed that Cisilent® Type G met all Chinese standards. From September 2020, the system was installed over a length of 200 m on the section between Xinqiao and Dezheng Station. From project study, planning, laboratory test to installation as well as on-site measurements, the project duration was approx. 1.5 years. The operator is very satisfied with the results and plans to equip further sections with our product. This pilot project was implemented in cooperation with our Chinese partner Zhejiang Tiantie Industry Co. Ltd. and Chinese experts.
