Production of the concrete segments for the North West Rail Link's skytrain will start late this year at a factory in Mulgrave, near Windsor, it has been announced.

In a joint statement, local MPs Kevin Conolly (Riverstone), David Elliott (Baulkham Hills) and Ray Williams (Hawkesbury) said the NSW government had entered into a $20 million deal with the manufacturer.

It includes building the concrete segments that make up the 4-kilometre elevated skytrain that will run between the future Bella Vista and Rouse Hill train stations, and upgrading the plant.

Mr Elliott said the upgrade work was expected to start next month, subject to approvals, with more than 180 new local jobs expected to be created at the Hawkesbury factory.

Mr Williams said the local workforce would be trained in the latest international techniques in pre-cast concrete production. 

Subject to planning approvals, Hanson – which currently employs about 35 people at the Mulgrave plant – will supply more than 1150 pre-cast concrete skytrain segments to the builders of the skytrain, Salini Impregilo.

“Segments will be delivered to the skytrain construction site at night,” Mr Elliott said.

The $340 million contract to build the skytrain, including a landmark cable-stayed bridge over Windsor Road at Rouse Hill, was awarded in December 2013 to Salini Impregilo.
