Beenleigh, Cleveland and Gold Coast train commuters had a long afternoon with all trains between Yeerongpilly and Roma Street stations suspended until just before 4pm.

TransLink said the trains had been suspended due to a possible person trespassing along the track.

Passengers could have to wait up to 75 minutes while trains between Moorooka and Roma Street stations would run express, the organisation warned.

Trains were suspended from about 2pm until TransLink confirmed the routes were open again.
