The union has released a calendar of the strikes planned for November and flagged there could be major disruptions in December - if the state government doesn't cooperate.
The action that will really impact commuters includes the union not operating certain trains and bans on cleaning, so Sydneysiders can expect dirtier platforms and train carriages.
Here is a day-by-day rundown of the strike action:
November 4: A 24-hour contractor blitz where there is a ban on rail employees working with any non-Sydney or NSW Trains workers. This could impact the regularity of services.
November 7: A ban on work associated with the Sydney Metro will continue for several weeks.
November 18: A ban on cleaners using scrubbing machines or vacuum cleaners for 48 hours.
November 19: A ban on cleaners and station staff removing graffiti for a week.
November 21: A ban on operating 4GT rollingstock, which are the Millennium and Waratah trains that operate mostly on the following lines: T2 Inner West and Leppington, T3 Bankstown, T5 Cumberland, T7 Olympic Park and T8 Airport and South. Commuters can expect major delays on this day.
November 22: Ban on hosing platforms for one week.
November 24: Ban again on cleaners using scrubbing machines or vacuum cleaners for 48 hours.
November 25: Ban on operating 4GT rollingstock, which impacts the T2 Inner West and Leppington, T3 Bankstown, T5 Cumberland, T7 Olympic Park and T8 Airport and South lines.
December 2: A network-wide stoppage means all train lines across Sydney won't be operating or will be extremely infrequent.
The rail union also has other industrial action planned that will only impact workers like training new staff, signing on or off at locations other than their home depot and attending planning meetings.
