Construction of platforms has commenced across six new stations on the Sydney Metro – Western Sydney Airport line, marking a major milestone for the 23-kilometre project.
At Bradfield Station, the new metro platforms are already in place, while the large island platform at the Airport Terminal Station site is about 50% complete. Measuring 95 metres in length and 10 metres in width – double the width of platforms at Gadigal Station – the Airport Terminal platform is designed to accommodate high passenger volumes and travellers with luggage.
Installation at the Airport Terminal Station will take approximately 25 days, using a 60-tonne crane to lower 119 precast concrete segments, each weighing six tonnes, to the station floor 25 metres below ground. Once in position, the segments are bolted and concreted into place.
As one of the busiest stations on the new line, Airport Terminal will feature wide platforms, large lifts, and widely spaced ticket gates to maintain smooth passenger flow. A covered walkway will link the station to the airport terminal in about three minutes.
Platform construction has also begun at Airport Business Park and Orchard Hills stations, with further installations scheduled to roll out sequentially across the line. Work continues at all sites, including concreting, steelwork, and formwork as station structures take shape. Track laying is progressing in both the north and south tunnels, on the viaduct near the Warragamba pipelines, and at the stabling and maintenance facility.
The project has now reached its peak construction workforce of 14,000, with 3,000 workers currently on site. Once operational, the metro will carry up to 7,740 passengers per hour in each direction, with a 15-minute journey time between the Airport Terminal and St Marys, where connections to the T1 Western Line will be available.
Running between St Marys and Bradfield, the new metro will serve as a key transport link for Greater Western Sydney, connecting communities with the new Western Sydney International (Nancy-Bird Walton) Airport.
