The class 83.10 was a new locomotive of the Deutsche Reichsbahn and was put into service in 1955 and 1956. It was intended to be used on secondary routes, for which a top speed of 60 km / h and a drive wheel diameter of 1,250 mm were sufficient. The wheelset and the first coupling axle were combined into a Krauss-Helmholtz steering frame . The construction of the 83.10 series was created together with the 65.10 series . The locomotives received hot steam regulators, mixer preheaters, decentralized sandboxes and sheet metal frames. The machines were able to move a load of 1,000 t on the level at a speed of 60 km / h.

history

After the delivery of the first locomotive in 1955, the machine was immediately tested in the VES-M hall . Various tests revealed numerous defects which, however, could no longer be taken into account in the ongoing series delivery. Some problems could be eliminated in the course of various improvement work. The series was never convincing and was only built in 27 copies due to the emerging switch to diesel operation . On the Ore Mountain routes, on the other hand, it did well in passenger train traffic. The large stocks were also judged to be cheap. From August 1969 to August 1970 five machines were located in BW Aue, which were used on the Zwickau – Johanngeorgenstadt route.

In 1974, the 83 1008, 1012, 1024 and 1025 were the last machines to be retired. None of the 83.10 series has survived.

technical features

The fully welded locomotives had a sheet metal frame. They had a box-shaped mixer preheater. The reversal was done with compressed air, this form of reversal did not prove itself and was expanded again. The hot steam controller that was initially available was also replaced by a wet steam controller due to problems.

The first drive axle had 10 mm side play, the flange of the third drive axle was weakened. The two trailing axles under the coal container were mounted in an outer frame bogie.
