Queensland Rail have added 14,000 seats to the South-East Queensland network, with 32 extra weekly services at peak times being implemented next month.
This comes after the upgrade of 193 three-carriage trains to six carriage trains in December.
Transport Minister, Mark Bailey, says commuters travelling during the morning and afternoon peak on the Shorncliffe, Cleveland, Redcliffe Peninsula, Ferny Grove, Springfield, Gold Coast and Airport lines would benefit.
