The steam locomotive series SB 629 was a passenger train - tank locomotive series of the Südbahngesellschaft , which were also procured in larger numbers by the Imperial-Royal Austrian State Railways (kkStB) as kkStB 629 , by the Austrian Federal Railways (BBÖ), by the ČSD and by the PKP .
history
The origins of the 629 series go back to the 15 locomotives of the Südbahn (629.01–15), which were built between 1913 and 1915. It was intended as the successor to the 229 series and was intended for passenger trains and light express trains . Various specifications such as weight per meter and increased performance led to the 2'C1 'wheel arrangement. This wheel arrangement , also known as “Pacific”, was widely used internationally, but was only used in Austria for this series. The smooth running of the new type was very much appreciated. The top speed was set at 85 km / h, although 110 km / h were reached without any problems during test drives.
The good results prompted the kkStB to order locomotives of this type as well. 25 locomotives with the designation 629.01-25 were delivered between 1917 and 1918. After the First World War, only ten of the kkStB series remained, but all of the Südbahn locomotives were in Austria. At the BBÖ , the Südbahnloks were given the designation 629.101–115; the kkStB locomotives kept their numbers, but 15 numbers were unoccupied because they were handed over to the ČSD .
Based on the positive experience, the BBÖ procured another 30 pieces, which were delivered as 629.26–50 between 1920 and 1921. In 1926 another 25 units were reordered (629.56–80) and delivered in 1926/27. The last five locomotives (629.500–504 with Caprotti valve control ) were delivered in 1927/28; but after bad experiences they were converted to Lentz valve control . This meant that there were 85 locomotives in stock. After the First World War, it was also rebuilt in Czechoslovakia , which had received 15 pieces from the kkStB. The ČSD had 234 units as series 354.1 in around 1941. In 1921/22 the PKP procured ten pieces from Krauss in Linz , which they classified as the OKm11 series.
A further need for increased performance led to the development of the 2'C2't series 729 , the later ÖBB 78 .
In 1938, after the connection of Austria to the Third Reich , the BBÖ in the German Reichsbahn were incorporated, the locomotives were on the series 77.2 as 77201-265 and 77281-285 redrawn.
When the ÖBB took over after the collapse of the Third Reich, the locomotives, some of which had come to other railways as a result of the war, were given the following numbers:
- 77.01–10 formerly from kkStB series 629.01–25 (years of construction 1917/18)
- 77.11–40 formerly from BBÖ series 629.26–55 (years of construction 1920–22)
- 77.242–264 formerly from BBÖ series 629.57–80 (years of construction 1926/27)
- 77.66–80 formerly from Südbahn series 629.01–15 (years of construction 1913–15)
- 77.281–285 formerly from BBÖ series 629.500–504 (built in 1927/28)
The last two digits of the serial numbers remained the same as for the Deutsche Reichsbahn. The newer locomotives (built from 1926 onwards) retained the 200 position at ÖBB because of the design differences.
Five machines remained in Yugoslavia after 1945 ( JDŽ 18 ) and two came to ČSD (354.1500 and 1501).
In the 1960s the cash register began, but the well-known locomotive type remained in use almost until the end of the steam traction.
The following remained as museum locomotives in Austria:
77.66 of the Austrian Railway Museum, which is written as 629.01 (Südbahn) and is looked after by the 1st ÖSEK in the Strasshof Railway Museum ,
77.244 of the Lienz Railway Museum, which is, however, written as 77.250,
as well as the 77.28 of the ÖGEG , which was put back into operation in 2007 after processing in Cluj ( Romania ).
Other specimens have been preserved in the Czech Republic , Slovakia , Slovenia and Liechtenstein .

The ČSD series 354.1
In addition to the 15 629s (354.121–35) taken over by the kkStB , there were initially 30 replicas made by the Škoda works in Plzeň in 1920/21 , which differed from the original design (354.101–20), among other things, through two domes with connecting pipes and 354.136-45). As a result of multiple repeat orders, 234 units were in use at ČSD in 1941 , with continuous improvements such as larger driver's cabs, electrical lighting and a cast-iron ring chimney instead of a cobel smoke trap.
The last design (354.1220-229) had a smaller clearance profile so that no steam dome connecting pipe could be installed. The shortened chimney made smoke deflectors necessary.
In 1930, Škoda built five machines with Lentz valve control and small tube superheaters based on the Austrian model. However, both changes did not prevail at ČSD.
After the Sudetenland became part of Germany in October 1938, a total of 49 locomotives came to the Deutsche Reichsbahn , which were classified there as the 77.3 series. During the Reichsbahn era, the locomotives were also used on routes in the Old Reich in Bavaria, Saxony and Silesia. Some of them were even in express train service.

The PKP series OKm11
Convinced by the positive experience in Austria, the Polish State Railways ordered ten units in 1922 following a series under construction at Krauss . The locomotives were classified as OKm11 and used in Galicia .
commitment
The Südbahngesellschaft initially used the 629 as a replacement for obsolete tender locomotives, also before express trains on the feeder routes to their mountain railways on Semmering , in Tyrol and in present-day Slovenia . After the fall of the Habsburg Monarchy, the machines popular with the staff were used in the direction of the new eastern borders, i.e. on the Eastern Railway , the Northern Railway , but also on the Wels – Passau and Linz – Summerau routes. From 1937 they were also used on the Northwest Railway . Apart from these main areas of application, the 629 and 77 series could be observed almost everywhere in the Austrian route network.
The last locomotives, including some of the first examples from 1913, were in use in the Vienna area, where they hauled passenger trains on the northern line to Bernhardsthal and on the northwest line to Retz until they were retired in 1976 .
Like Austria, ČSD used the machines in passenger train service but also on short routes in front of express trains.
