The Newcastle site of the company responsible for building NSW’s Waratah trains has been forced to shut, following the discovery of asbestos in dust samples.
Staff are being briefed on the discovery after the asbestos was found in a storage area about a week ago.
Air samples tested negative but dust samples were found to contain asbestos in certain areas.
The owner of the Cardiff site, RailCorp and WorkCover were aware of the presence of asbestos materials, which was built in the 1920s.
A rail consortium is contracted to build 78 new Waratah trains by 2013 under a public-private partnership signed by the NSW government in 2006.
