THE Springfield train line is taking shape with services due to commence this year, but concerns linger about a potential car park shortage.
The train line and stations are visibly coming together, with significant construction milestones being reached.
A spokesman for Transport Minister Scott Emerson said the foundations had been laid at Springfield station, located opposite Woodcrest College.
The arches for the elevated platforms at Springfield Central station, adjacent to the Orion Town Centre, have been installed.
These will form the structure of the station.
The rail alignment is also well under way - 6000 sleepers, 8km of track, 80 overhead masts and 5700 metres of signal and power cable have been installed in the 2km section of rail between Richlands station and the bridge over the Logan Motorway Interchange.
The 900m long, 15m high elevated bridge carrying the rail line over the Logan Motorway Interchange is also substantially complete, with the last concrete poured prior to Christmas.
Construction on the 9.5km extension to the Darra to Richlands line began in October 2011.
Public transport advocacy group Rail Back on Track spokesman Robert Dow said the major issue facing Springfield commuters was getting to the station.
Mr Dow said 100 car parks were not enough considering the poor bus feeder services.
Richlands train station has 650 car parks which are often all taken during the morning peak hour.
Mr Dow said many commuters would drive from Redbank Plains to Ipswich stations rather than Richlands so they could get a park.
He said leaving Springfield and Springfield Central with fewer car parks wouldn't relieve the stress placed on Wacol and Gailes stations.
"If they think anyone is going to walk up to the train station they are dreaming," he said.
There needs to be 500 car parks. There are only 100 there at the moment. If they are temporary that's fine, because there is no way known they are going to get a proper bus feeder service.
