Sydney Metro Stage 1 Northwest Rail Link


  • PEB/PSD Installations









Platform Screen Door / Platform Edge Barrier Installation

The Sydney Metro Northwest, formerly the North West Rail Link, is the first stage of the Sydney Metro that became operational in 2019. Sydney Metro Stage 1 Northwest railing is the first to install Platform Edge Barriers Doors Systems and Platform Screens Doors Systems, allowing safe access in and out of the train for passengers.

Ascent worked alongside UGL and CIMIC and supplied skilled Installation teams undertaking Australia’s first PEB/PSD along stage 1, spanning from Tallawang Road Station to Chatswood Station and covering 13 Sites.

Our workers assisted with mark-out and site surveying, complete installation, alignment of all equipment and undertook testing commissions from start to end of the project.

We worked on several locations across Sydney: Tallawong Road Station, Rouse Hill, Kellyville, Bellavista, Norwest, Hills Showground, Castle Hill, Cherrybrook, Epping, Macquarie University, Macquarie Park, North Ryde, Chatswood

The $7 billion Sydney Metro Stage 1 Northwest railing project features 36 kilometres of track between Chatswood and Rouse Hill, single-deck trains with about 50% more hourly capacity than double-deck carriages, 15 kilometres of tunnels, 13 stops, including eight new stations, 18 sets of doors per platform and 72 individual doors per station, 4000 commuter parking spaces, a train stabling facility, a 4 km ‘skytrain’ viaduct, and 4 km of bridges.

Our challenges


For the scale of such a large project, our client needed skilled teams and personnel with mechanical backgrounds who worked to a very fine tolerance and had excellent attention to detail. Ascent was able to source that type of people, and our exceptional work qualified us to stay for the entire project’s duration.


The logistical side of the project required a tremendous amount of coordination with other contractors in the same area. Our teams pre-planned and booked all the materials for every stage of the project to ensure they were delivered on-site on time and scheduled the work crews in advance for each specific site they were to work on.

Working on public transportation projects means time is of the essence, and meeting the deadline is paramount to resuming regular daily schedules. Our teams worked around the clock for a period of 15-16 weeks to complete the entirety of the project on time with no delays.The equipment alignment was extremely sensitive, and it required skilled tradespeople to understand how to install and align the equipment and machinery. Our mechanical and installation teams performed an outstanding job and delivered an excellent finished product.
