Airtrain, the operator of Brisbane’s airport rail service, is suing the Queensland government over the introduction of a 50-cent statewide public transport fare scheme. Multiple outlets report that Airtrain says negotiations with the state have broken down after the flat-fare policy reduced its revenue. Airtrain alleges it is owed compensation of $4.75 million as a result of the revenue impact, according to The Age and the Sydney Morning Herald. The Brisbane Times and The Age also describe the legal action as following the rollout of the 50-cent fare scheme. The dispute centers on whether the fare policy changes require financial adjustment to the rail operator. The reports indicate that Airtrain’s claim relates to lost revenue under the fare arrangement, and that the matter proceeds to court because an agreement was not reached during discussions with the Queensland government. The outlets do not report a court outcome yet.
