The Class 23 locomotives were passenger train steam locomotives operated by the Deutsche Bundesbahn. Starting in 1950, a total of 105 units of this newly designed class were built. The Veluwsche Stoomtrein Maatschappij (VSM) owns two Class 23 locomotives: 23 076, which was the first to arrive at the VSM in 1976, and 23 071, which followed in 1978. Both locomotives remain operational to this day.
