Sydney Commuters Hit By Major Delays

Train delays and a major road accident caused chaos for Sydney commuters Monday morning, with rail passengers facing cancelled services and packed trains, and buses delayed more than an hour amid gridlock on the Anzac Bridge.

The T1 North Shore, T2 Inner West and Leppington, T3 Bankstown, T5 Cumberland and T8 Airport South Line all faced delays after a "larger than expected number of staff" called in sick.

Buses replaced some train services, but officials warned commuters to expect major delays and to allow for extra time.

"We are working to provide frequent services but please check your trip and use real-time apps to avoid delays," Sydney Trains tweeted.

"We appreciate your patience."

Passengers vented their frustration on social media.

Meanwhile, a fatal accident on the Anzac Bridge just after 7am shut down all but one city bound  lane of traffic, causing backup on Victoria Road through Rozelle, Drummoyne and Sydney's inner west.

A male motorcyclist was killed after being struck by a truck in the east bound lanes of the Western Distributor.

Emergency crews responded but he died at the scene.  Police are appealing for witnesses with dashcam footage to come forward.

Crews opened all city bound lanes of the Anzac Bridge at about 9am, but traffic remained queued on the City West Link for up to eight kilometres through much of the morning, while traffic on Victoria Road queued for up to five kilometres.

Traffic on Parramatta Road from Ashfield to Camperdown was also heavy.

"Motorists are strongly advised to use an alternative route," Live Traffic NSW said earlier Monday.

Buses in the area were delayed for up 60 minutes, but have now returned to normal operating times.
