Okay, not TSW, but this is remarkable. Scotrail have released a sound file of ALL of their announcements: https://files.scotrail.co.uk/ScotRail_Station_Announcements_June2022.mp3 The files has been split up https://drive.google.com/drive/folders/172W6sXnvlr7UcNLipO8BTw417_KRz9c5 and indexed https://docs.google.com/spreadsheets/d/1jAtNLBXLYwTraaC_IGAAs53jJWWEQUtFrocS5jW31JM/edit#gid=0 But the best bit... is that it has been set to music: https://www.matteason.co.uk/scotbeats/ LNER (https://t.co/Et6385RXmI) and Southeeastern (https://t.co/fFcl7ZLekj) announcements also avilable, but not to music. Yet.
The interesting thing would be the license conditions. Do you know anything about that? EDIT: ScotRail holds the copyright in these files. Under their publication scheme, the following terms apply: Where ScotRail Trains Limited holds the copyright in its published information, the information may be copied or reproduced without formal permission, provided that: ● it is copied or reproduced accurately. ● it is not used in a misleading context, and ● the source of the material is identified. I think this means DTG can use these files in TSW if they want. Of course it will only in a limited scope.
