A Derailment Is Causing Major Delays Across Sydney's Train Network This Morning

Commuters heading into work by train this morning should prepare for their trip to take a bit longer than usual, with a train derailment at Circular Quay causing major delays across the network.

The maintenance train derailed around 5.30am on Tuesday, March 3, between Circular Quay and Wynyard stations, and repair crews are currently on site.

The three main lines impacted are the T2 Inner West and Leppington, T3 Bankstown, and T8 Airport and South Lines, which are all battling major delays. Services are only running one way on the City Circle, first stop Town Hall, and a limited number of buses are supplementing trains between Circular Quay and Central. The T8 Line also starts and terminates at Central and will not run around the City Circle.

Commuters are being advised to allow plenty of extra travel time, especially if they're travelling to the airport, and to consider using local buses and the light rail as alternatives.

The T1 North Shore is also experiencing delays because of a trespasser at Central Station earlier.

Due to the flow-on effects of the derailment, the rest of the train network is also experiencing delays, with all passengers told to allow for extra travel time and to check their real-time apps as some services have altered their stopping patterns.
