The Project

Regional Rail Project - Momentum Trains Dubbo

About the Project

Momentum Trains is working with the NSW Government to replace the ageing NSW regional rail fleet of XPT, XPLORER and Endeavour trains. The new trains will improve safety, amenities, accessibility and reliability for customers who travel from Sydney to many regional centres in NSW, as well as Canberra, Melbourne and Brisbane.

In 2020, the new Regional Rail Maintenance Facility was named The Mindyarra Maintenance Centre, which is a Wiradjuri word, it means to ‘fix’ or ‘repair’. It was chosen to represent the work that will occur at the new Regional Rail maintenance facility. Click here for more information.

About Momentum Trains - Dubbo, New South Wales

Building new Regional Trains

CAF is an international leader in the design, production, maintenance, overhaul and supply of rolling stock, rail system components, simulators and associated equipment. CAF is responsible for the supply of the new passenger intercity and regional trains. The trains will be Diesel Electric Multiple Units (DEMU) with bi-mode capability. Bi-mode capability allows the trains to operate as electric trains where overhead power is in place. The new fleet will consist of 117 carriages which will form 29 new trains; 10 regional intercity trains (3 car sets), 9 short regional trains (3 car sets) and 10 long regional trains (6 car sets).

The new fleet will be predominantly manufactured in Spain. The final fit out of the fleet known as train completion works, will take place at the Mindyarra Maintenance Centre. The fit out activities involve installing such items as seating, lighting, electrical components, buffet equipment, handrails and CCTV to complete the build of the fleet. 


The design of the new regional trains is based on the CAF Civity model. Civity is a family of modular low-floor trains designed for regional and commuter services

Constructing the new Mindyarra Maintenance Centre

CPB Contractors has been engaged by CAF to design and construct a new train maintenance facility in Dubbo. CPB Contractors is the Australasian construction company of the CIMIC Group. CPB contractors work across all key sectors of the construction industry, including roads, rail, tunnelling, building, defence and resources infrastructure.

The construction work will include utility diversions, earthworks, pavements and drainage, steel structures and roofing and cladding for the main build of the Mindyarra Maintenance Centre, plus fit out works.

The maintenance building will have three tracks inside, as well as workshops and storage areas for spare parts. Once operational, this main building is where most of the maintenance work will occur. The size of the main building will be approximately 220 metres by 70 metres.

External to the main building, there will be additional facilities which include a wheel lathe and train wash building using non-potable water, an administration building, storage areas and tracks external to the building.

A new mainline track will be built on the northern side of the facility for passenger and freight train services. To build the new main line, rail work includes installing ballast, sleepers and rail and tamping activities, signaling and commissioning.

Construction of the Mindyarra Maintenance Centre commenced in 2020. 

Construction of the Mindyarra Maintenance Centre also includes:

  • an administration building with staff amenities, a security building and storage area with loading dock
  • realignment of the Main Western Line through the site
  • six maintenance rail tracks (three tracks within the maintenance facility and three external)
  • a connection to the Main Western Line on the western side of the site
  • refuelling, decanting and provisioning infrastructure
  • road infrastructure such as access roads through the site and a staff car park
  • adjustments to utilities, power supply, relocation of a stormwater detention basin, and earthworks
  • landscaping

Maintaining the Regional Trains

UGL will perform all asset management and maintenance activities for the new regional rail fleet of 117 rail cars, training simulators and the maintenance facility in Dubbo for at least 15 years.

UGL is a specialist end-to-end asset solutions provider. UGL has a proven track record in delivering projects and outcomes for clients, from global corporations, government agencies, public institutions and private enterprises, through to smaller-scale operators.

UGL will provide a range of opportunities for local and Aboriginal businesses, through jobs, workforce skill development and supply opportunities.

Information about the opportunities available to businesses during operations and maintenance of the new fleet and facility will be provided closer to the commencement of this phase of the Project. It is anticipated that tenders for work to support UGL during this phase will be progressively released.
