NOeLB / kaiserlich-Koeniglichen Oesterreichischen StB 0-6-2 Locomotives in Austria


Class Details by Steve Llanso of Sweat House Media

Class T/187 /198 (Locobase 8082)

Data from Josef Pospichal's Lokstatistic site -- [], accessed and [], both accessed 13 January 2007. Works numbers were 3819-3821 in 1898.

In 1898, the Gurktalbahn, a narrow-gauge system in KSrnten, the southernmost Bundesland in Austria, bought three of these small radial tanks to run between Treibach-Althofen and Klein Klÿdnitz. They were considerably smaller than the U class that was more widely distributed because the GB's profile was much flatter and thus less demanding. Linz supplied two more of this design (works # ) to the KnhnsdorfvEisenkappel (Vellachtalbahn) lokal bahn, which was operated by the Sudbahn.

These looked particularly toylike in having tiny drivers, a flower-pot spark arrester top to the stack, and a large cab. All of the Guktalbahn locomotives survived the demise of the Austro-Hungarian empire, the Anschluss with Nazi Germany in 1938 (at which point they were designated Baureihe 99 7801-7803), World War II, and the Soviet occupation. They finally went to the scrapyard in 1959 (198.02) and 1960 (the other two).

T4 joined the Yugoslav State Railways in 1918 as their JDZ 187-001. T5 stayed in the south and operated under BB+, colors until 1932.


Class U / 298 (Locobase 4643)

The Club 760 website gives us the data and says that their engine was originally U6 of the Nieder Oesterreich bahn. But information from Josef Pospichal's Lokstatistic site -- [], accessed 1 August 2006 -- shows that U6 was Krauss Linz works# 3805 in 1898 and that it first operated on the Ybbstalbahn and was retired in 1973.

In any case it ran over several narrow-gauge railroads for the next 82 years. It was then retired, only to be restored to service on the Taurachbahn.

Some info from [] (16 Jan 2004).

Data confirmed and expanded by [], accessed 13 August 2006. Several builders contributed to this widespread class: Krauss in Linz, Wiener Neustadt, and Bÿhmisch-MShrische Maschinenfabrik of Prague.


Class U / 298.5 (Locobase 6355)

Data from a catalogue of Krauss locomotives hosted as part of [] (visited 17 Nov 2004).

According to the site, this locomotive was developed from the Steyrtalbahn locomotives shown in Locobase 6352. As such, it was a widely used saturated-steam narrow-gauge design.

The Club 760 website gives slightly different data for its locomotive and says that their engine was originally U6 of the Nieder Oesterreich bahn. See Locobase 4643.

See also [] for U37 and data from the table presented on pages 427, 429 of the Groupe VI. - GTnie civil. - Moyens de transport. DeuxiFme partie. Classes 32 (Tome I), part of the series of Rapports du Jury Internationale of the Exposition Unverselle Internationale de 1900 Paris Exposition, hosted on the website of Le Conservatoire numTrique des Arts & MTtiers ([], Accessed 21 August 2005).


Class UV / 298.2 (Locobase 4642)

Data from [], a catalogue of Krauss locomotives and [] (last accessed 3 December 2006).

The Wikipedia entry for the U designs (as translated by Google at 8

[][], accessed 1 August 2006) says that the NiederOesterreich LandesBahn ordered this design as a larger version to pull a heavier train. Krauss delivered 2 in 1902 (works# 4785-4786) and one in 1905 (works# 5329).
