The Bamberg V 80 Locomotives. The 10 class V 80 diesel locomotives were brought together at the beginning of Era IV in the Bamberg District. They were used in the area between Frankfurt, Cologne, and Nürnberg up to 1976 pulling commuter trains on flat terrain. These trains consisted of rebuild cars and older rolling stock. The "Silberlinge" / "Silver Coins" were the newest commuter cars at that time and were kept for the push/pull lines in the metropolitan areas.
