The BR463 is Deutsche Bahn’s classification of the super-modern Mireo EMU, and it has been recreated in DB Regio livery by developers RSSLO for Train Simulator Classic with scenarios for the Nürnberg - Donauwörth Route. It also has customisable programmable destination displays and is compatible with station audio announcements. Store Link here: https://store.steampowered.com/app/3403060/Train_Simulator_DB_BR463/
