The steam locomotive series BBÖ 478 was a shunting - Tender Locomotive number of Austrian Federal Railways (BBÖ).
history
It was common practice in Austria to move locomotives with tenders that had become too weak for line service. In the 1920s, however, the BBÖ was faced with a massive shortage of shunting locomotives, as the locomotives used so far were very old. Attempts were made to stop the shortage by buying Swiss locomotives (series BBÖ 130 , BBÖ 279 and BBÖ 379 ). It was clear, however, that the most sensible solution was to buy your own new shunting locomotives.
Since the 378 branch line locomotive was being developed at the same time , the aim was to design the shunting locomotive series similar to this, while matching as many components as possible. The 478 series was created without the running axles . In addition to the changes to the frame that this caused, the 478s received slightly larger cylinder diameters, otherwise the two series were practically the same.
As with the 378s, the 478 series immediately went into series production without a test locomotive. The BBÖ added a total of 50 pieces to its inventory. They were initially used in Vienna Westbahnhof , Wiener Neustadt and Villach , and later in almost all larger train stations. In the 1930s, some received welded water tanks for better sealing.
In 1938 it was initially taken over by the Deutsche Reichsbahn as 92.2301-2350. But they were soon redrawn as 92.2501-2550. After the Second World War , the ÖBB remained 43 pieces, to which they assigned the series number 392 while retaining the serial numbers . The last 392s were part of the ÖBB until 1972.
The 392.2510 and 392.2530 were preserved; both are owned by the ÖGEG .
The WOLFSEGG-TRAUNTHALER KOHLENWERKS AG in 1941 purchased a similar machine in 1959 a Giesl ejector received, boiler pipe throttling and micro spark arrester. It was retired in 1974.
