Commuters in Sydney have been warned to expect major delays this morning after a work train derailed between Circular Quay and Wynyard.

Commuters in Sydney have been warned to expect major delays this morning after a maintenance cart derailed between Circular Quay and Wynyard.

Frustrated Sydneysiders are saying on social media their morning train services are delayed for up to 72 minutes.

Hundreds of services are expected to be cancelled after the incident, and delays are already hitting the T2 Inner West and Leppington, T3 Bankstown, and T8 Airport and South lines.

Good morning, Beau & Pip signing on.

A limited number of buses will be running between Circular Quay and Central.

There are also delays on the T1 North Shore Line due to a trespasser at Central earlier.

Sydney Trains said those heading to the airport will need to board at Central Station, as services have halted through the City Circle.

This comes a week after commuters were stranded for up to an hour on crowded platforms due to a fire alarm going off, a medical emergency and wiring issues affecting almost all train lines.

NSW Shadow Minister for Transport Chris Minns has blasted the frequency of these major incidents on the tracks, saying the network is a “mess” and people have a right to be angry about it.

“It now seems that commutes are going to blow out for hundreds of thousands of Sydneysiders week-in week-out,” he told news.com.au. “It’s just a mess and Sydneysiders are rightly frustrated about it.

“It speaks to the persistent neglect of the network from the NSW government.”

The vehicle has since been removed from tracks and trains will resume on City Circle but major delays will continue throughout the morning.

A spokesman at the Transport Management Centre said they were not aware of any injuries caused by the maintenance cart derailing.

Commuters have been urged to allow extra travel time, plan ahead and consider using the Light Rail or buses to get to the city.

The Rail, Tram and Bus Union has urged commuters not to take it out on train workers.

“While we understand commuter frustrations entirely, and in fact share many of those frustrations, we’re urging commuters to try and keep their cool and show respect for workers during this difficult time,” RTBU NSW Secretary Alex Claassens said.

“We get it. Workers often have frustrations too, but it’s important not to take those frustrations out on those who are just trying to do their job.”
