Sydney trains confirmed that trains are still running on the T8 Airport, but on limited services.

"Trains are running, however, they may be less frequent while our teams work to restore trains to the timetabled (schedule) after the earlier incident at St James," Sydney Trains said on X.

Buses are also replacing trains between Macarthur and Campbelltown.

Commuters are warned that services will change at the last minute, with trains still running but on a delayed schedule.
