NSW train services are getting back to normal after a four hour strike that started at midnight.
The stoppage affected Sydney's rail network as well as intercity and regional services.
Some services were replaced by buses and some delays could affect services on Thursday morning.
Sydney Trains chief executive Matt Longland said commuters should not expect a fully operational timetable until 8am.
The strike is the latest chapter in the long-running dispute between The Rail, Tram and Bus Union and the government over a new enterprise agreement as well as safety modifications to the mothballed Korean-built New Intercity Fleet.
The union and management are scheduled to meet again on Thursday.
