Major milestone for Sydney Metro – Western Sydney Airport as platform construction begins

At the Bradfield Station site, the new metro platforms are already in place, while the large island platform at the Airport Terminal Station site is approximately 50 per cent complete.  

The supersized platform at Airport Terminal will be the largest on the line at 95-metres-long by 10-metres-wide, which is double the width of the platforms at Gadigal Station. The extra room will provide plenty of space for passenger movement and accommodate for those travelling with luggage.  

The installation of the platform at Airport Terminal will take about 25 days and requires a 60-tonne crane to lower 119 precast concrete segments to the station floor, 25 metres below ground. The segments, each weighing six tonnes, are then pieced together and secured in place with bolts and concrete to create the platform.  

The Airport Terminal Station will be one of the busiest on the new metro line and will feature wider platforms, large lifts, and widely spaced ticket gates to ensure smooth passenger flow. A three-minute covered walk will link the station to the airport’s terminal.

Platform installation will successively roll out across the stations and last week started at Airport Business Park and Orchard Hills stations.  

Across all station sites work continues with concreting, steelwork, and formwork underway as main station structures begin to take shape. Track laying is underway in both the north and south tunnels, as well as at the viaduct near the Warragamba pipelines and at the stabling and maintenance facility.

Recently the project reached its anticipated peak construction workforce of 14,000, with 3,000 workers currently on site working to deliver the project.  

The new 23-kilometre Metro will transport up to 7,740 passengers every hour in each direction, with a fast, 15-minute metro trips running from Airport Terminal to St Marys, where passengers can join services on the T1 Western Line.  

New metro rail extending between St Marys and Bradfield will become a transport spine for Greater Western Sydney, connecting communities and travellers with the new Western Sydney International (Nancy-Bird Walton) Airport.
