Saint-Vallier, September 19, 2022

METALLIANCE, a Group GAUSSIN subsidiary, announces an order for 12 vehicles for the construction of the Sydney Metro - Western Sydney Airport in Australia

The order includes 5 TSP50, 2 VMS30, 2 Menriders 20C and 3 VMS Maintenance for delivery in 2023. It reflects the renewed confidence between METALLIANCE and the Sydney Metro tunnelling contractor.

METALLIANCE (EURONEXT ACCESS FR0010492181), a company which specializes in the design and

manufacture of industrial equipment and mobile machinery, announces an order for 12 vehicles, including 5 TSP50s, 2 VMS30s, 2 Menriders 20Cs and 3 VMS Maintenance, from the Australian joint venture between CPB Contractors (CIMIC Group) and Ghella (CPBG). These vehicles are destined for the Sydney Metro - Western Sydney Airport project in Australia, which is delivering twin tunnels and six new stations. The vehicles will be delivered in 2023.

A relationship of trust between METALLIANCE and its partners in Australia

This new order is part of METALLIANCE's wider involvement in the construction of Sydney Metro, as it follows the recently announced order for 12 VMS (see PR of June 7, 2022) for the construction of the central section of Sydney Metro West. METALLIANCE has been contributing to the project for nearly 10 years, with over 40 vehicles supplied for the first two phases of Sydney Metro construction, including 25 for Sydney Metro City & Southwest in 2017 and 15 for Sydney Metro Northwest in 2013.

The client companies, CPB and Ghella, previously worked together on the Sydney Metro City & Southwest and Brisbane Cross River Rail projects. The joint venture also took over the METALLIANCE fleet of the Brisbane project: 3 TSP50, 2 VMS25, 2 Menriders 20C, 1 VMS Maintenance and 2 BUTORS TEM-100-T. These repurposed machines will join the newly ordered equipment which testifies to the satisfaction of CPBG with the technology and equipment of METALLIANCE.

The METALLIANCE range of vehicles is a confirmed success on Sydney Metro sites

A structuring project for the Australian metropolis

Sydney Metro - Western Sydney Airport is the new metro railway line which will service Greater Western Sydney and the new Western Sydney International (Nancy-Bird Walton) Airport. A city- shaping project, the 23-kilometre new railway will connect the Western Sydney Aerotropolis in the south with St Marys in the north.

As Australia's largest city, Sydney is the first and currently the only city in the country to have a fully automated metro rail system.

"Our company is delighted to participate in such a large-scale project in Australia, which will better serve the economic capital of the country and link it to the new international airport under construction. Known for having invented the rubber-tired train, and present today on very large construction sites throughout the world, METALLIANCE is proud of the range of its technologies as well as the know-how of its teams. This capacity to respond with flexibility and creativity to the needs of its customers allows METALLIANCE to intervene today on this demanding project, the usefulness of which will be widely perceived in the region," says Jean-ClaudeCOTHENET, CEO of

METALLIANCE.
