The steam locomotive series BBÖ 378 was a tank locomotive series of the Austrian Federal Railroad (BBÖ).
history
In the 1920s, the competition from road traffic was already noticeable in rail operations. The branch line traffic in particular needed to be made more attractive. For this reason, the BBÖ commissioned the Floridsdorf locomotive factory to design a superheated steam tank locomotive, which was supposed to provide more power than the Gölsdorf series 178 and was intended to replace numerous other older series. In addition, a unifying essential components with the same time located in development should Verschublokomotive number 478 be achieved. The branch line locomotive was given the axle formula 1'D1 'and the designation 378 . Series production began immediately without building a prototype locomotive.
The machines were equipped with Lentz valve control; attempts with other types of control did not bring any advantages. Like the 178 series, they initially received solid cast disc wheels. Later deliveries returned to cast steel spoke wheels on the running axles, and in the last series also on the driving axles. The BBÖ put 167 of this series of locomotives into operation by 1931.
From 1938 the Deutsche Reichsbahn classified the locomotives of this series as 93.1301–1467.
In 1941 the Slovak State Railroad (SŽ) ordered 25 pieces in a slightly different form, which were given the designation 431.0 . After the Second World War, these locomotives remained with the ČSD .
In 1944 the Wiener Lokalbahnen also procured a copy of this series with a steel fire rifle, but it was too powerful for the tasks it was intended for, so that it was exchanged for the ÖBB 92.2256 in 1951 . The ÖBB initially referred to the former WLB machine as 93.1468, but later as 93.1500.
During the Second World War, eleven pieces were lost and a total of 28 pieces came (partly as reparations) to the JDŽ in Yugoslavia, so that the ÖBB 128 pieces remained. In 1958, 72 units were equipped with a Giesl ejector and boiler pipe throttling - six of them also with micro-spark arresters - which increased their performance by around 30%. The JDŽ also equipped one of its machines with a flat ejector in 1960.
The 93s were in use in the entire secondary line network of the ÖBB. It was the last standard-gauge series of steam locomotives in the ÖBB's inventory. After the official end of steam traction in Austria, some copies remained as "strategic reserves" until 1982.
