The protected action including reduced speed limits and bans on working with contractors would start on January 15 and last for three days across the NSW trains network.
The rail union says it's part of a bid to resume negotiations that broke down as workers threatened to upend New Year's Eve festivities in Sydney.
The new actions did not involve high-level strikes or bans on using certain trains, Rail, Tram and Bus Union state secretary Toby Warnes said.
"There are no massive disruptions," he told ABC Radio.
"But there might be some flow-on effects to try and get management to wake up and come back to the bargaining table."
Workers continue to demand four annual wage increases of eight per cent but that's been dismissed by the Minns government as unaffordable.
The government has not formally budged from its original offer of 11 per cent over three years including superannuation increases.
The months-long battle flared in the days before Christmas as pub and bar operators, a casino, Luna Park and the NSW Labor government railed against train driver work bans planned for New Year's Eve.
NSW Police earlier warned of "grave concerns" for public safety if the one million people expected to line Sydney Harbour on the night struggled to leave after the fireworks.
The union backed down on the eve of a Fair Work Commission hearing as the opposition warned that "chaos (had been) kicked down the road".
