In 2004, the Swedish National Audit Office criticized the process of building and financing the Arlanda Line, and stated that the State had taken more financial risk than the Riksdag had been informed about. It also criticized the Government for giving additional financial support to A-Train in the form of guarantees without informing the Riksdag, and having an unclear management strategy. It also commented that the traffic forecasts during planning were incorrect. The original plans showed an economic benefit of SEK 4 billion. However, because A-Train is free to set its ticket prices as it wishes, the high prices resulted in too few passengers taking the Arlanda Line for it to be of economic benefit to the Swedish community, and the line failed to maximise its economic impact through reduced road congestion and emissions.
