This week, the 2026-27 NSW Budget was delivered by Treasurer Daniel Mookhey. Rail-related investment is led by a $16.1 billion commitment to Sydney Metro over four years, $2.4 billion in new investment for Parramatta Light Rail Stage 2, record annual heavy rail maintenance spending of $2.1 billion, and continued delivery of regional rail fleet renewal. Broadly, transport infrastructure investment has seen an uptick with an 8.4% increase compared to the prior Budget. Here, we unpack the key commitments and their consequences for major rail projects in NSW.
Sydney Metro
The Budget commits $16.1 billion over four years for Sydney Metro projects, with $4.5 billion allocated in 2026-27 alone. Key areas of investment include:
- Sydney Metro West: $12.9 billion towards a new 24-kilometre underground metro railway with stations at Westmead, Parramatta, Sydney Olympic Park, North Strathfield, Burwood North, Five Dock, The Bays, Pyrmont and Hunter Street in the Sydney CBD, targeting opening in 2032.
- Sydney Metro–Western Sydney Airport: $2.2 billion towards a new 23-kilometre railway delivering six new metro stations between St Marys and Bradfield City Centre, connecting residential areas with employment hubs and linking airport travellers to Sydney’s broader public transport network.
- Sydney Metro City and Southwest: $988.3 million towards the Southwest Metro Line, which will open this year as part of the M1 Northwest & Bankstown Line, converting 13 kilometres of century-old heavy rail into high-frequency, fully automated metro, modernising 11 stations and increasing train frequency. The conversion provides capacity for an additional 100,000 passengers per hour across the broader metro network.
Parramatta Light Rail Stage 2
$2.4 billion in new investment has been allocated to Parramatta Light Rail Stage 2. The full project will extend light rail services between Parramatta CBD and Sydney Olympic Park, comprising approximately 10 kilometres of new track, 14 new stops, new river and road bridges, an expanded stabling and maintenance facility, new light rail vehicles, active transport links and public domain upgrades. Procurement has commenced for Stage 2a (Parramatta CBD to Wentworth Point), which includes 4.5 kilometres of track, nine new stops, two new bridges and additional light rail vehicles. Enabling works commenced in October 2025.
Heavy Rail Maintenance
The Budget includes record annual heavy rail maintenance investment of $2.1 billion for signalling systems, maintenance and station upgrades to improve Sydney and NSW Trains services. The Rail Reliability Plan will establish new incident response capability within the Rail Operations Centre, while upgrading signal and electrical infrastructure to reduce incidents and delays.
Fleet Renewal and Rolling Stock
$844.2 million over four years will be directed towards replacing ageing XPT, XPLORER and Endeavour trains serving regional NSW.
The new Intercity Mariyung Fleet will be delivered with associated power supply upgrades, with $746.0 million in spending over four years.
The Tangara fleet will be extended to operate until 2036, with $396.3 million committed over four years to address obsolescence, ageing, safety and customer experience issues and to enable a longer-term replacement. $151.6 million will be directed over four years at planning the Future Fleet Program business case for a long-term domestic rolling stock pipeline with a 50% local content target and a modern double-deck suburban passenger train to replace the Tangara fleet. The Millennium and OSCAR fleets will also be considered.
Other Commitments
- The Rail Service Improvement Program will see $1.1 billion over four years targeted at simplifying and modernising the rail network, integrating Sydney Metro City and Southwest with Sydney’s train network, and delivering more frequent services, including on the Illawarra, Airport and South Coast lines.
- South West Sydney Rail Planning will be supported by $19.8 million over four years for a joint NSW and Australian Government business case considering possible future rail connections between Bradfield and Leppington/Glenfield, and between Bradfield and Campbelltown/Macarthur. The business case includes consideration of both metro and heavy rail options for the Bradfield–Leppington corridor.
- $49.5 million has been committed over four years for planning and development of the freight rail network connecting Port Botany and Western Sydney.
- $42.1 million over four years, with $20.8 million in 2026-27, will be focused on improving capacity, access, efficiency and reliability of the regional rail network and movement of freight in and out of regional areas.
- $234.4 million over four years will improve safety and reduce delays where Inland Rail intersects the Newell and Olympic highways.
- Woollahra Train Station is expected to be completed in 2029, with $30.9 million allocated to 2026-27. The station will support the delivery of up to 10,000 new homes through state-led rezoning around Woollahra station and the existing Edgecliff station.
- $428.5 million has been allocated over four years for station upgrades to achieve compliance with the Disability Standards for Accessible Public Transport, improving amenity, access and safety across the network.
Next Stop? Delivery
The 2026-27 NSW Budget signals continued momentum in the State’s rail pipeline, with several themes of strategic relevance for infrastructure participants:
- Metro delivery intensifies. With $4.5 billion committed in 2026-27 alone across three active metro programs and a fourth in planning, Sydney Metro remains one of the State’s most significant transport delivery programs. The imminent opening of the Southwest Metro Line and the progression of Sydney Metro West towards its 2032 opening date create a sustained pipeline of procurement and delivery activity across tunnelling, stations, systems, operations and maintenance.
- Local content and fleet pipeline planning. The Future Fleet Program signals the Government’s strategic intent to establish a long-term domestic rolling stock pipeline with a 50% local manufacturing content target. This has significant implications for rolling stock manufacturers, component suppliers and the broader Australian rail manufacturing sector, and sits alongside the Australian Government’s National Rail Procurement and Manufacturing Strategy.
- Western Sydney rail connectivity. The South West Sydney Rail Planning business case and Western Sydney Freight Line planning reflect the Government’s recognition that rapid growth in Western Sydney demands new rail connections — both passenger and freight. These early-stage programs are likely to inform future major project commitments.
- Record maintenance spend. The record $2.1 billion heavy rail maintenance allocation, combined with the Rail Reliability Plan and the Rail Service Improvement Program, represents a significant uplift in spending on the existing network. This creates opportunities for signalling, communications and asset maintenance contractors.
- Light rail expansion. Parramatta Light Rail Stage 2 has moved from planning into active procurement, creating near-term opportunity across design, construction and rolling stock supply.
