Workers in Sydney's north shore and inner west can expect a longer commute when they return to work on Monday, with track work on trains and light rail taking place this week.

It will be a stark reminder to many of those travelling that the holidays are over, with many commuters forced to jump between buses, light rail and trains to travel to work in the next week.

Minister for Transport, Andrew Constance, said commuters would need to plan their trips carefully this week in light of the track work.

"We're doing this work in the quietest period to minimise disruption in heavier commute times, but it's all essential," he said.
