Thousands of additional seats for commuters will be available on trains today when six-car units replace three-car units on Queensland Rail services.
The change has been made possible by the roll-out of 35 New Generation Rollingstock trains onto the network.
Transport Minister Mark Bailey says the new services will increase carrying capacity by more than 46,000 seats a week across the south-east Queensland network.
Mr Bailey also claims passengers will immediately notice the difference on the Beenleigh, Shorncliffe, Ferny Grove, Cleveland, Northgate and Doomben lines from this morning.
