Back in 2012 the NZTA cut back the back the platform at the Ellerslie train station by 2m to give themselves enough space to build a fourth northbound lane from Ellerslie Panmure Highway just north of the Main Highway bridge. The NZTA are currently working on stage 2 which is the creation of that lane.
I haven’t been on the Ellerslie Platform for a few years but I was previously a daily user and remember just how noisy it can be with the motorway so close and exposed to the station – and the noise is only likely to get worse with an additional lane. As such I was curious as to whether the NZTA planned to do anything reduce the noise for passengers waiting for a train so I asked the NZTA. Their reply is below
The project will include anti-distraction screens with noise reduction properties. The product is Plexiglass Soundstop® and will be 1.0m high on top of the TL6 barrier. The TL6 barrier is 1.45m high from road surface. Giving a total height of 2.45m from road level. The length of the screens is 435m from CH250 to Main Highway Bridge (CH685). The Plexiglass Soundstop is 15mm thick (same as Nelson Street) but will be transparent Midnight Blue in color with vertical black bird deterrent markings.
Acoustic engineers have completed a model of before and after predictions, specifically looking at the noise changes at the platform. Their conclusion was “ The proposed 2.5m barrier between SH1 and Ellerslie Station is predicted to achieve a noticeable reduction in road traffic noise level for patrons waiting on the platform.”
Recently they also uploaded the video below giving a rough idea of what the blue noise wall will look like.
Once complete it will hopefully make waiting for a train at Ellerslie a bit more pleasant.
