The series 70.0 was a tender locomotive for light passenger trains. It was commissioned by the Royal Bavarian State Railways as a class Pt 2/3. Between 1909 and 1916 Krauss built a total of 97 machines in Munich. In order to optimize the traffic on the local railways, a door was installed at the rear, through which the heater entered the train in order to take over the tasks of the conductor. Later, the doors were partly removed in favor of a larger coal box. This locomotive was also characterized by the exceptionally large distance between drive and running axles of 4,000 mm. This resulted in an economical but economically sensible lightweight construction of the machine, which proved to be outstanding.After the Second World War, the German Railways took over 89, which fast up to 65 km/h, locomotives and continued to use them until the 1960s on southern German branch lines. The last locomotive was retired in 1963.This text is machine translated.
