Freight train derails at Banksmeadow, Sydney, but no train or road delays are expected

A freight train has derailed in a busy industrial Sydney suburb but is not expected to delay passenger lines.

The train derailed at Banksmeadow early Wednesday morning, with 10 carriages being pushed off the track, three of which were tipped on their sides.

Transport NSW could not confirm when the route will be cleared but said the incident will not delay passenger services or cause road closures.

Firefighters inspect the contents of the train cars to determine if hazardous materials need to be removed from the scene.

NSW Police were also investigating the incident.

Fire and Rescue NSW said the train derailed after colliding with another train as they drove together and confirmed there were no injuries.
