Train services resume in Sydney but delays ongoing

Major delays are still expected across Sydney's train network after a police operation wrapped up at Westmead Station.

Crowds of people were stuck at stations across the western suburbs, and there are also major delays on the North Shore Lines.

People are being told to get replacement buses, delay travel, or brace for long waits.

Limited train services are running from Blacktown to Richmond and Penrith.

Other train services are set to resume from now, but major delays are still expected.
