The first regularly scheduled ICE train, "Münchner Kindl", departed from in Hamburg at 5.53 am on 2 June 1991. For the inauguration of the ICE system, ICE 1 trainsets operated on one ICE line from Hamburg to Munich, via Hanover, Fulda, Frankfurt, Stuttgart and Augsburg, at hourly intervals. This coincided with the inauguration of the first two German high-speed rail lines Mannheim-Stuttgart and Hanover-Würzburg, which required 18 trainsets. At the time of the inauguration a total of 25 trainsets were available. Originally, the trainsets were made up of 13 intermediate cars: four first class, restaurant car, service car and seven cars second class.
