Neubaulokomotive

As a new locomotive, the built for the German Federal Railroad steam locomotives of the series 10, series 23, series 65, series 66 and series 82 and built for the German State Railroad steam locomotives of the series 23:10, Series 25.10, class 50.40, range 65.10, range 83.10, series 99.23-24 and 99.77-79 designated series.

With this choice of terminology, the new designs of the two postwar German railways to distinguish designed from the times of the German State Railroad Company (DRG) unit locomotives. Significant differences of the new buildings to the earlier unit locomotives are of all-welded plate frame ( made ​​of heavy plates ) instead of the bars and the frame also fully welded powerful steam boiler with a stronger emphasis on the Radiative and mostly also use a combustion chamber.

New locomotives of the German Federal Railroad

The new locomotives of the German Federal Railways were referred to in this unit as locomotives 1950.

The boilers of these locomotives were constructive evaporated to a constant heat flux of 70 kg water per square meter of heating surface per hour, short term up to 85 kg / m² h designed (by comparison with the standard locomotives of DRG was supported by a heat flux of 57 kg / m² h assumed ). The superheater were designed to continuously vapor temperatures can be achieved of more than 400 ° C. The rust areas you bemaß it nearly to limit the Feuerungsverluste during the downtime. In the interest of good erosion of the coals in the fire bed also due to user mistakes or worse coal qualities in addition to abundant supply of air to the bottom ring of the boiler standing on a powerful blowpipe effect and thus better Feueranfachung than the older unit locomotives was taken. Not least for the purposes of the operation of the auxiliary equipment such as air and feed pump with steam they tried to use hot steam control instead of the proven Naßdampfreglers.

When you drive the locomotives was a struggle over a far-reaching application of rolling instead of sliding bearings. At high reverse speeds of the vehicles ( eg in class 23 ) value was placed, as on good working conditions for engineers by well- closed cabs with padded seats, Summary of display instruments for consoles etc.

Visually distinguish the new locomotives of the DB itself. Unity of the older locomotives by silvery boiler casing tension bands, the arrangement of the sand pits on either side of the boiler in the amount of the round instead of on top of the boiler as well as the total quieter lines

New locomotives of the Deutsche Reichsbahn (GDR)

The new locomotives of the Deutsche Reichsbahn in the GDR, the boiler was designed for a continuous evaporation capacity of around 65 to 75 kg / m² h. In contrast to the Federal Railroad rust areas were generously sized, to use also significantly less energy -containing lignite or brown coal briquettes or mixtures of briquettes and coal as a fuel can on the railways.
