Steam locomotive class 35.10 of the railway company of the German Democratic Republic (Deutsche Reichsbahn).

With the introduction of the EDP numbering at the Deutsche Reichsbahn, the formerly named series 23 locomotives were also provided with the new series designation 35.10. The locomotives were a development outcome based on the two pre-series locomotives 23 001 and 23 002. The locomotives of the 35.10 series were very much appreciated by the operating staff because they were smoothly running and had a low coal consumption.
