A rail union plan to shut down the NSW transport network's Opal card readers is set to cost the government about $2 million every day.
The Rail, Tram and Bus Union (RTBU) is pushing ahead with a plan to deactivate the state's Opal readers, preventing commuters tapping on to pay for trips, as part of its ongoing industrial action.
Over the weekend, the union withdrew its original application to switch off the readers after a legal threat from the government - filing a new application on Monday.
