The New South Wales government has claimed the cost of the city's new metro rail line could blow out by hundreds of millions of dollars if the state's rail workers are allowed to go ahead with this week's planned industrial action.

On Monday the premier, Dominic Perrottet, announced that his government was filing action against the Rail, Tram and Bus Union (RTBU) in the Fair Work Commission seeking to block the fresh round of industrial action.
