Logan commuters travelling on the Beenleigh line between 16 November and mid-December should check whether their usual peak train will stop at their station.
Nine weekday morning and afternoon peak services will skip three or more stops between Dutton Park and Salisbury during work associated with Cross River Rail.
The other stations affected are Fairfield, Yeronga, Yeerongpilly and Rocklea.
The changes are scheduled to continue until mid-December.
For some passengers, the StationLink route 19 bus between Rocklea and the PA Hospital busway station may be quicker.
Check individual services through Translink.
