Class Details by Steve Llanso of Sweat House Media

Class 10 / BR 35 (Locobase 7771)

See Locobase 1198 for discussion of this Golsdorf design. Data from the German-langugage version of Wikipedi -- [], accessed 5 August 2006.


Class 110 /BR 35 (Locobase 1198)

Maurice Demoulin, Locomotive Actuelle ... (Paris: Librairie Polytechnique Ch.Beranger, 1906), p 230. See also Dr. R. Sanzin, "Die Lokomotiven auf der Intertionalen Austellung in Mailand 1906, 19. 3/5 gekuppelte vierzylindrige Verbund-Schnellzuglokomotive (Bauart Prairie) der oesterischen Staatsbahnen ...", Zeitschrift des Oesterreichischen Ingenieur- und Architeckten-Vereines, Vol LVIII Nr. 51 (21 December 1906), p 717.Works numbers were in 1585 in 1905; 1634, 1640-1644, 1649-1651 in 1906; 1712-1715 in 1907

Another Karl Golsdorf locomotive that shows the grace that could accompany competence. A visit to England in the mid-1890s is credited with inspiring Golsdorf's adoption of more elegant lines in his designs. A four-cylinder compound, the Prairie type was high-pitched, showed a relatively uncluttered boiler barrel, low brass dome, angled LP cylinders outside with slide valves worked outside as well, and a low running board with arches over the second and third driver sets. One curious feature was the placement of the trailing axle as far back as the frame would permit. External tube diameter was 53 mm.

A E Durrant The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1972), added a levelling comment that these engines went through several class identifications. 110 for saturated locomotives, 110.500 for steam driers, and 10 for superheat, "as though Goldsdorf, knowing that defects existed, had reserved the basic class number for the final perfected version."

The Third Reich's Anschluss with Austria in 1938 led to the locomotive's reclassification as BR 35.


Class 110.500 / BR 35 (Locobase 7770)

Data for this entry from [], accessed 5 August 2006. Floridsdorf works numbers were 1679-1680 in 1906, 1772-1776 in 1908, 1859-1864 in 1909. Wiener Neustadt works numbers were 4914-4919 in 1909.

See Locobase 1198 for discussion of the handsome Golsdorf 110 design. Reflecting A E Durrant's comment that the designer seemed to be seeking improvements, this batch of 110s featured a steam drier.


Class 229 (Locobase 1201)

Data from [] . See also "Passenger Tank Locomotive, Austrian State Rys," The Locomotive, Volume 19 (15 May 1913), pp. 102, 103. Builders included BMMF, Floridsdorf, Krauss Linz, StEG, and Wiener Neustadt.

This was a Karl Golsdorf design, one in which acceleration was at least as important as any other single design variable In addition to the 239 built for the KKStB from 1904 to 1918 and the 11 delivered to the Sudbahn, 17 more were converted from 129-class engines. 35 superheated variants formed class 29 and appear in Locobase 20105.

In Slovenia, according to the Slovenian Railway Museum website -- 8

[] (in March 2002) -- this ubiquitous class served the Ljubljana - Tarvisio and Ljubljana - Novo mesto - Karlovac lines. Later they would be relegated to local lines such as Kranj - TrPic, Ljubljana - Vrhnika, Ljubljana - Kocevje, and Celje - Dravograd.

This class serves well as an example of what the breakup of the Austro-Hungarian Empire in 1918-1919 did to its vast locomotive holdings and as a general history lesson on the travails of Central Europe in the first half of the 20th Century. 69 229s remained with the BB+, which added 11 Sudbahn engines as 229.5 and 10 from the former Eisenbahn Wien - Aspang (EWA) as 229.8. Austria's engines were again redesignated after the 1938 Anschluss with the Third Reich. That regime's DRG assigned BR 75 701-790 to the unmodified 229s. After Germany's defeat in 1945, the 63 survivors were reclassed once more as Class 75. As such, the class ran until the last engine was retired in 1962.

The rest of the class was distributed to newly independent states carved out of the old Empire and to former enemies as war reparations. In the latter case fell the five Italian engines, which were classed FS 912. The great majority of the rest -- 145 locomotives altogether -- went to the new Czechoslovakia as their class 354.0; five of these were superheated between 1926 and 1934 and reclassed 355.0. They differed from the 354s in having the two steam domes connected by an external pipe; a sixth superheated in 1944 did not have the connecting pipe. From 1936 to 1940, 5 more were modified by changing the rear carrying axle and redesignated 353.1. Five CSD locomotives operated in the DRG and were designated 75 901-905. The last Czech engines were taken out of service in 1967.

Poland's 22 became OK l12; 21 of these were later redesignated 75 851-871. Yugoslavia designated its 25 as JD- 116, of these 9 assumed BR 75 791-799 after Nazi Germany's conquest of Yugoslavia in 1941. Hungary received 15 in 1939,when Sndslowakei, in eastern Czechoslovakia, was thrown to that country as part of the Nazi takeover in 1939. They became MAV 343.3.


Class 29/DR 75.8/OBB 175 (Locobase 20105)

Data from Tomasz Galka,"OKL11", Standard-Gauge Locomotives in Poland, [], last accessed 4 November 2016. Roster data from Josef Pospichal's roster website at [], also accessed 4 November 2016. BMMF works numbers were 411-443 in 1912 anf Florisdorf works numbers were 2078-2079 in 1912.

Galka notes that although the saturated-boiler 229 cross-compounds used widely in Austrian commuter service (Locobase 1201) were quite satisfactory, the positive results of superheating suggested a revision of the design. Golsdorf increased the HP cylinder's diameter and substituted piston valves for the original slide valves.

Galka reports that the update "was not as as successful as its prececessor" even though "coal and water consumption were lower." They lacked power and the boiler's reduced ability to evaporate water sometimes compromised operation.

Twenty-six continued in Austrian service through the breakup of the Austro-Hungarian Empire, the 1938 Anschluss with Germany (when they were classed by the DRG as 75.8, and the re-establishment of an Austrian national railway as the OBB. The last was retired in 1962.

29.18 was sent to Yugoslavia's JDZ. Nine wound up in Poland, operating first out of Krakow, then from Katowice from 1930 until the German invasion. A total of five returned to Poland after 1945 but saw no mainline service.


Class 30 / DRB 90.1 (Locobase 4685)

Data from the table presented on pages 409, 411 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) and Wikipedia and Data from Maurice Demoulin, Locomotive Actuelle ... (Paris: Librairie Polytechnique Ch.Beranger, 1906), p 260. Josef Pospichal's [], accessed 10 February 2008 for builders' data. The latter shows Floridsdorf supplied the first 17 (works #935, 1000, 1060-1061, 1063-1074). Batches from Wiener Neustadt and StEG, as well as more from Floridsdorf filled out this large class.

Locobase was a little surprised to discover that the 30 had one of the largest boilers of the tank locomotives of this wheel arrangement. It was yet another design from the fertile mind of Karl Gÿlsdorf . The 1900 Exposition Jury explained that the requirement was for a locomotive to serve the Viennese suburbs where the ruling grade was as steep as 2% and the minimum curve radius was 120 meters. In tests, the engine pulled 135 tonnes up the 2% at 35 km/h (22 mph).

The accompanying diagram shows a tidy, balanced design carrying a dumbell on top of the boiler. This latter structure is the typical 2-dome arrangement with connecting external pipe.

Unlike many of the Austro-Hungarian classes, all of the 30s remained in the Vienna region after the empire broke up at the end of the First World War. Although they operated in the Linz, Villach, and Innsbruck districts, most persisted in the Vienna region with all but 32 retiring by 1938. In that year of the Anschluss that pulled Austria into the Third Reich, the DRG classed these as Baureihe 90 1. Eight were left at the end of World War II and these were retired by 1957. Others went into Soviet service.


Class 329 (Locobase 1202)

Data from [], last accessed 31 August 2006. See also "Compound Locomotive, Austrian State Railways," The Locomotive Magazine, Vol XIII (15 March 1907), p. 51.

Built for all parts of the Austro-Hungarian Empire, 95 went to Austria (also to Czechoslovakia as 354.701 class), 2 to Serbia (Banjaluka-Dobrlijn) later Yugoslavian 107 class, and 65 to Hungary (later 323 class). Poland operated some of these as the Oi1-11 class. Italian war reparations included some of the class, designated FS 687.

Kalla-Bishop (1973) notes that these Golsdorf compounds were fitted with Clench steam dryer. The front 3 feet of boiler was void of water; steam let in at the bottom of this chamber rose up past the firetubes where it theoretically would be dried. Unfortunately the apparatus usually leaked water.

Data from [] (25 January 2004)


Class 429 (Locobase 1203)

Two-cylinder compounds of the group of basic superheated Prairies of the old Austro-Hungarian Empire. Supplied in two batches: The first 57 had a piston valve on the HP cylinder, slide valve on theLP. 126 later engines had piston valves on both cylinders. Laster operated in Austria, Czechoslovakia, Poland, and Yugoslavia.

A E Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1972) wrote that the heating surface was 118.55 sq m (1,276 sq ft) and superheat 27.2 sq m (293 sq ft); the current figures came from the German Wikipedia site -- [], accessed 5 August 2006.


Class 429.900 (Locobase 1204)

Data from A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966); "Ol12" on Tomasz Galka's Standard-Gauge Locomotives in Poland website at [], last accessed 20 December 2021; and Skice Iglavni Podatci Lokomotiva diagram book (Zagreb, 1955), archived by Srecko Ignjatovic at [] , plate 46.

Simple-expansion variants of the basic superheated Prairies of the old Austro-Hungarian Empire.

Later operated in Austria, Czechoslovakia, Poland, and Yugoslavia.
