The SB 570 was four-coupled express train - Tender locomotives of the Southern Railway Company in Austria . Largely structurally identical locomotives were also procured from the Kaschau-Oderberger Bahn as the It series .
history
Just like the kkStB (cf. kkStB 470 ), the Südbahn faced the problem of procuring an express locomotive for its mountain routes. Eustach Prossy , his successor Karl Schlöss and the chief designer at the StEG locomotive factory , Hans Steffan created a four-coupled locomotive with a leading two-axle bogie. In contrast to Gölsdorf's 470, the SB 570 was implemented as a superheated steam twin locomotive .
The 570 series was built in two copies in 1915 at the StEG locomotive factory. The 2'D locomotives were originally intended to replace the class 109 on the Karst routes , but remained in Vienna , where they were initially used up to Mürzzuschlag , and only from 1916 did they also go to Ljubljana (now Ljubljana, Slovenia ). Since the type, which was intended as an express train locomotive , did not meet expectations, no further construction was carried out, but in large parts it served as a model for the BBÖ series 113 (later 33 of the ÖBB).
In 1938 they were given the designation 33 001 and 002 by the DR and were therefore used as express train locomotives . The ÖBB classified them as 133.01-02 in 1953 (which made them a sub-series of the more modern 33 in terms of numbers), but decommissioned them as early as 1954.
No copy of this series has survived. In the Warsaw Railway Museum, however, there is an identical locomotive from a Polish replica series.
The It series of the Kaschau-Oderberger Bahn
The Kaschau-Oderberger Bahn (KsOd) carried out test runs with the 570.01 on its main line in 1916. The positive result of these tests led to the ordering of five slightly modified locomotives as the It series with the numbers 351-355 from the StEG locomotive factory .
Outwardly, the conical smoke chamber door based on the Hungarian model was particularly striking. In addition, the driver's cab could be extended because of the larger turntables of the KsOd. The correspondingly changed dimensions are not taken into account in the table.
When the KsOd was nationalized in 1921, the machines came as 455.001−005 to the Czechoslovak State Railway ČSD, which did not decommission them until the 1960s.
