Sydney train commuters are again being warned of '"major delays", with the state's opposition leader Luke Foley labelling the network as "shambolic".
The train network went into meltdown on Tuesday afternoon, and thousands of passengers were stranded on platforms because of the long delays.
Transport NSW tweeted on Wednesday morning: "MAJOR DELAYS ACROSS THE NETWORK due to staff availability & earlier incidents. Trains running at reduced frequency. Buses supplement some services. Listen to station announcements for the latest."
Mr Foley was himself caught up in the train chaos at Town Hall station on Tuesday night, saying the situation was "shambolic".
"Frankly it was a danger to public safety," he told Network Seven on Wednesday.
Mr Foley says the Berejiklian government needs to fix the transport chaos before spending $.2.5 billion of taxpayer's money on rebuilding two stadiums.
