PUBLIC transport lobby group Rail Back on Track has called for the Ipswich rail line to be included in a 15-minute frequency trial set to begin on the Ferny Grove line.
The trial was announced by then LNP candidate Campbell Newman during the Queensland election campaign.
The 15-minute trains will double the services offered in non-peak times over the next two years and are due to start in the middle of the year.
The Ipswich line carries 13,900 commuters between Oxley and Rosewood stations each day, only 400 shy of the patronage on the Ferny Grove line of 14,300.
The lobby group spokesman Robert Dow said the $18 million project should be expanded to include Ipswich line.
Mr Dow said there is enough evidence already to suggest the trial would also be a success between Darra and Rosewood.
"What we would like to see is when the LNP get settled is to look at the core network with a view to investing in the network. The Ipswich line must be a priority because it is the engine room of the network," he said.
A Translink spokesperson said Ipswich commuters have benefitted from timetable changes last June, with trains operating every six to 12 minutes in the busiest period of morning and afternoon peaks from Ipswich to the city.
The spokesman said at all times during the day trains operate every 15 minutes or better on the Ipswich train line between Darra and the city.
The additional frequency between Darra and Central has meant commuters on the Ipswich line have more express services, better reliability and less overcrowding.
- 2100 commuters use the Richlands line during peak times each day.
- Less than 350 commuters use the Rosewood line stations during peak times.
- Train patronage increased by 5.7% last quarter, up 700,000 trips across the network.
