NSW Transport Minister David Elliott has torn into The Rail, Tram, and Bus Union as commuters prepare for another day of industrial action.

Sydney commuters are being told to avoid travelling on trains as the union industrial campaign continues.

The timetable has been altered to cater for 75 per cent of trains being taken out of service.

The Rail, Tram, and Bus Union is refusing to operate overseas-built carriages after another breakdown in negotiations with the State Government on the safety of the mothballed intercity fleet.

The union has rejected the government’s plan to spend more than $260 million making safety modifications to the trains.

NSW Transport Minister David Elliott told Ben Fordham it’s “the most politically motivated industrial action since the sacking of Gough Whitlam”.

“This is an act of shame and dishonesty for the Labor movement,” Mr Elliott said.

“The Union is trying to use these strikes to get people to vote Labor.”

Mr Elliott also said he is “very close” to taking the union to the Fair Work Commission

NSW Deputy Premier Paul Toole told Ben Fordham he is over the union playing “silly buggers”.

Mr Toole is also imploring Labor leader Chris Minns to get involved to “move the goalposts”.

Sydney Trains Chief Executive Matt Longland told Ben Fordham roughly 150 trains will not leave the depot today and more action may be set for next week.

“We’ve been notified of further action next Wednesday and next Friday.”
