The steam locomotives of DR Class 23.10, (from 1 June 1970 Class 35.10) were passenger train engines built for the Deutsche Reichsbahn in East Germany after the Second World War.Is produced in H0 scale to many train model railway.
History
The Class 23.10 was an evolutionary development by the DR of the DRG Class 23 standard locomotives or Einheitsdampflokomotiven built earlier by the Deutsche Reichsbahn-Gesellschaft. Only two of the latter were completed due to the onset of the war. The same dimensions were used for the driving and running gear, but the locomotives were given IfS/DR mixer-preheaters, boilers equipped with combustion chambers and a large driver's cab. The feedwater dome was omitted from locomotives numbered 23 1003 and later. The first of 113 units was deployed in 1955, and they were used for light to medium express train services, being allocated numbers 23 1001 to 23 1113.
With the introduction of EDP numbering on 1 January 1970, all locomotives were re-numbered to 35 1001 to 35 1113.
The last engines were retired from Nossen in May 1977, number 35 1113 however had to be reactivated due to the energy crisis and continued in service until 1985.
The locomotives were equipped with tenders of Class 2{{prime}}2{{prime}} T 28.
