history

73,372 in the Ljubljana Railway Museum
ÖBB 55.5708 (ex 73.79) in the Strasbourg Railway Museum
ČSD 414 096 in the Railway Museum Lužná u Rakovníka

The kkStB procured these four-coupled locomotives from 1885 to 1909. The first machines (73.01-04) were procured for the Arlbergbahn , the 73.23-28 for the Galician Transversalbahn . All Austrian locomotive factories were involved in the delivery of the 73 series. A total of 453 locomotives were added to the kkStB inventory. They had the numbers 73.01–454 (73.300 remained unoccupied).

The 73 series locomotives were very powerful in their time and shaped freight transport in what was then Austria for 25 years. They were able to transport 1650 t at 30 km / h on the plain, 580 t at 15 km / h on a gradient of 10 ‰ and 220 t at 15 km / h on a gradient of 25 ‰. Their power was 700 hp.

The 73 series was mainly used in Galicia , Bukovina , Bohemia and Moravia , Vienna , Salzburg , Tyrol and Vorarlberg . After it had been ousted from freight traffic by more powerful locomotives ( 170 , 270 , 180 , 80 ), it was used in shunting .

After the First World War , the 73 series was divided among the successor states of the monarchy as follows: 233 units came as Tp15 to the PKP , 119 as 414.0 to the ČSD , 25 units as 424 to the FS , 17 to the CFR and four units the railways of the Kingdom of Serbs, Croats and Slovenes and later as series 133 to the JDŽ . The BBÖ remained 44 copies, the rest were lost in the war. The ČSD withdrew the last machine of the 414.0 series from their inventory in 1969 and handed it over to the National Technical Museum in Prague .

After the annexation of Austria by the German Reich , the Deutsche Reichsbahn classified all 44 BBÖ machines as 55.5701−5744. In the course of the fighting during the Second World War , former 73s came to the DR from the ČSD (55.5745−5819), the PKP (55.5832−5864 and 55.5866–5897) and the JDŽ (55.5865).

After the Second World War, the ÖBB remained 38 pieces, which were further referred to as series  55 . The last machine, 55.5708 (kkStB 73.79), was taken out of service in 1964 and given to the collection of the Austrian Railway Museum. The locomotive is coupled to a tender from the KkStB Tender series 36 in the Strasshof Railway Museum .

The ČSD locomotive 414.096, the last example of this series available in the Czech Republic, which was nicknamed Heligon , has been subjected to a general inspection in the Railway Museum Lužná u Rakovníka since 2009 . In April 2019 she drove on her own for the first time in 50 years and hauled several nostalgic trains in the following season.

The last Yugoslav machine, the former kkStB 73.372, is located in the Ljubljana Railway Museum together with a tender for additional oil firing .
