The steam locomotive SB 16a No. 301 was a tender locomotive of the Südbahngesellschaft (SB), a private Austrian-Hungarian railway company .
Emergence
Since it was foreseeable that the 60 km / h top speed of the SB 18 and SB 19 series would soon be too low to transport express trains on flat routes, the SB left a locomotive of the type at the Wiener Neustädter Lokomotivfabrik according to plans by Louis Adolf Gölsdorf 2'B build. The Wiener Neustädter Lokomotivfabrik received permission to build another example for the world exhibition. This was sold to the Austrian Northwest Railway (ÖNWB) after the exhibition .
technical structure
The rear coupling axle of the machines was placed behind the fire box, which, together with the extension of the wheel base of the front bogie to 1,320 mm and the coupling wheel diameter of 1,900 mm, led to very smooth running and a top speed of 80 km / h. However, due to the firebox being narrowed by the rear coupling axles, it lagged behind the SB 18 and 19 rows in terms of performance. They had outer frames, Hall cranks , sagging fire boxes and deep-set kettles . They had no equalizing levers , which suggests a rough run, and a little enough cab.
The SB 16a 301
For the numbering and row assignment of the SB locomotive, see the table.
Due to the stock market crash of 1873, no reorders were made from SB. However, the machine was trend-setting for the subsequent 2'B machines such as the SB 17a, b, c, d series .
The area where the SB locomotive was most recently used was Innsbruck . It was retired in 1914.
The RITTINGER of the ÖNWB
The ÖNWB had the shortest connection between Vienna and Berlin compared to other railway companies . However, between Vienna and Čáslav it had gradients of 10 to 14 ‰ and many curves of up to 285 m radius, which made it difficult to drive fast. In order to find the right type of locomotive for this route, the ÖNWB bought the RITTINGER on display there in 1874 after the Vienna World Exhibition .
At the ÖNWB the RITTINGER formed the series Ia with the number 81 . In 1889, the ÖNWB built a new standing boiler into the machine , widened the driver's cab and installed an ÖNWB type regulator.
The locomotive was initially used on the Vienna - Znojmo route ; later she was transferred to the Elbe line. Most recently she worked in the shunting facility in Reichenberg . After the nationalization of the ÖNWB in 1909, the kkStB designated the machine as 201.01 , which was the only representative of this series. The RITTINGER was sold to a Hungarian works railway as early as 1910 .
