Rail services on Sydney’s eastern suburbs and Illawarra lines are back to normal after a train derailment caused chaos on the lines on Wednesday.

A metal bar speared through a train floor, causing it to derail near Edgecliff Station.

About 700 commuters were evacuated from the train at 5.30pm (AEDT) after two wheels came off the track near the station.

No one was injured, and passengers were evacuated by police and rail staff to another train.

Hundreds of other commuters also had to be evacuated after their trains were trapped in the area because of the derailment.

On Thursday morning, The Transport Management Centre (TMC) said train services on the impacted lines had resumed.

“Trains on the T4 Eastern Suburbs & Illawarra Line have fully resumed between Martin Place and Bondi Junction after a train derailment at Edgecliff yesterday,” the TMC said in a statement.

It said all services had resumed after “incident response crews from Sydney Trains worked overnight to get trains running again”.

Sydney Trains chief executive officer Howard Collins on Wednesday said the driver noticed the eight-carriage train was sluggish before it stopped, and that a customer saw a metal bar come through the floor.

He said the passenger was treated for “a bit of shock” after the incident.
