Sydney Trains is facing significant disruptions due to urgent track repairs at Central Station, affecting multiple lines including the T1 North Shore, T2 Inner West, and T8 Airport and South lines. Commuters are experiencing extensive delays, cancelled services, and overcrowded stations, particularly at Ashfield, prompting warnings from Transport for NSW to allow extra travel time. The repair operation involves replacing a broken rail, which has been described as logistically complex. Frustrated passengers have taken to social media to express their dissatisfaction, calling for more proactive maintenance and criticizing the service during peak hours. Sydney Trains has advised riders to check transport apps and listen for announcements due to the potential for altered service routes and increased wait times. These disruptions are expected to persist through the morning peak commute.
