BR 628-4 - is a detailed add-on for Train Simulator Classic, representing the Deutsche Bahn (DB) Class 628.4, a twin-car diesel multiple unit (DMU) used for regional passenger services across Germany, particularly on non-electrified branch lines. Developed in the early 1990s as an evolution of earlier Class 628 variants, it was designed to replace older railbuses (e.g., BR 795, 798, and 515) and improve passenger comfort and operational efficiency. Between 1992 and 1996, 309 units were built, making the BR 628-4 a backbone of German regional rail services on non-electrified routes.
