Sydney's roads were heavily congested in the western suburbs on Saturday evening amid IT issues being blamed for the city's public transport woes, which continued throughout the evening as multiple sporting events got underway in Homebush.

The city's train system was in chaos for most of the day, with passengers stuck on trains between stations, major delays right across the network and travellers being told to simply catch the bus instead.

It led one train driver to vent his frustration to passengers of a lack of information from management. "You won't see our management, but they want you to be reassured by me making announcements to tell you that we have no further information," the driver said. "Thank you."

Sydney Trains said the problems were "a result of an IT issue across all transport agencies".
